Non-Technical Summary

Statement of Issues and Justification

How the proposed research addresses regional and/or national priorities and in context of stakeholder input:

The poultry industry in the United States underpins the global food system providing an efficient, economical and nutritious source of animal-based protein (meat and eggs). The industry foundation consists of breeding companies and growers/producers distributed throughout the nation (and the world) with a heavy concentration in states from which the members of Multistate Research Project NC1170 are drawn (e.g., Arkansas, California, Delaware, Georgia, Iowa, Minnesota, North Carolina, Virginia). The USDA Economic Research Service reports that the U.S. poultry industry is the world’s largest producer and second-largest exporter of poultry meat and a major egg producer. The USDA National Agricultural Statistics Service reported that the combined value of production from broilers, eggs, and turkeys in 2021 was approximately $47 billion. Many allied industries support and are impacted by the poultry industry, e.g., from grain producers and distributors to housing/cage manufacturers. Thus, the economic impact of the poultry industry to the financial health of the U.S. is enormous. The interactions of the poultry researchers involved in NC1170 with their stakeholders takes place via a variety of formats and opportunities so as to integrate our expertise with their needs and goals. These formats include, but are not limited to, organized informal meetings, workshops, and conferences (e.g., Poultry workshop at annual International Plant and Animal Genome meetings, annual National Breeders Roundtable, annual Poultry Science Association meeting), listservs, web-based tools/utilities useful to the industry, as well as collaborative ventures among research institutions and poultry industry businesses. Many NC1170 members have leveraged USDA-AFRI or other federal grants and have substantive collaborations with poultry breeders and producers. It is noteworthy that many NC1170 researchers not only utilize specialized poultry genetic lines for experimental analysis but also routinely employ commercially-selected foundational lines and crosses in their work.

The importance of the work, and what the consequences are if it is not done

Genetic improvements enabled the creation of a poultry industry that now produces the most widely consumed livestock commodity around the globe. The demand for poultry over the next decade is projected to increase even further as economic growth in certain regions drives the development of new markets. At the same time, the industry continues to face new and more complex challenges – rising feed costs, new disease outbreaks, changing climate – that threaten its ability to maintain production of an affordable and safe source of complete protein. The work of NC1170 focuses on using the power of poultry genomes to adapt to these challenges by making genetic improvements to chickens, turkeys, and other economically important avians. More specifically, NC1170 utilizes cutting-edge methods for genomics and bioinformatics to deeply mine poultry genomes and extract the pathways and molecular mechanisms that underlie phenotypes and determine how avians respond and adapt to their environment.  This work produces invaluable fundamental knowledge about poultry genomes, and it also provides the functional information that is needed to guide improvements in the industry’s breeding programs and management practices. These methods, and the sophistication in approach enabled by the expertise of this group, allow a depth of knowledge that is not achievable through individual efforts or more conventional research methodologies. The work of NC1170 will contribute knowledge needed to further adapt poultry to their environment, enhance disease resistance, improve welfare, and maintain efficiency of growth and reproduction. Because NC1170 brings investigators together with stakeholders, this work is tightly aligned with the needs of the industry. It is also important to emphasize that the work of NC1170 is important for training the next generation of the poultry workforce, particularly in the ‘omics tools and approaches that are fundamental to maintaining the industry. Undergraduate and graduate students, as well as postdoctoral scientists, benefit from training in the labs of NC1170 investigators, and are exposed early on to the value of interdisciplinary solutions and the utility of new technologies. They also have opportunities to interact with other scientists and stakeholders through the activities of NC1170 members and through attending the annual poultry workshop. The importance of this role of our multistate group should not be overlooked.

The technical feasibility of the research.

The collection of investigators who participate in NC1170 are deeply entrenched in mining poultry genomes to benefit the poultry industry, and ultimately to feed the world. Some members of this multistate have been involved with sequencing and annotation of poultry genomes since the first draft sequence for chicken was published in 2004. Sequencing and analysis of both the chicken and turkey genomes was accomplished with the direction and collaboration of NC1170 researchers. NC1170 members are experts in their various fields, and collectively bring a breadth of technical expertise to the table. These investigators are at the leading edge of applying the latest ‘omics techniques to their work, often enhancing methods and analytical tools in the process. Because of the collaborative nature of this group and its productive history, these advances are readily shared with other members, keeping the group itself at the leading edge of poultry genomics. Each of the investigators has extensive expertise in poultry and avian biology, which enables them to recognize and utilize the wealth of opportunities that are presented by participation in in NC1170. The group includes domain experts in virtually every aspect of avian physiology, which enables the work of this group to be conducted from a systems perspective. The methods employed by the NC1170 investigators are state of the art techniques for genomics, transcriptomics, proteomics, and bioinformatics, for the purpose of exploring the fundamental biological mechanisms underpinning growth, development, physiology, nutrition, immunity and animal health. Efforts range among all scales, from fundamental to translational to applied. Due to the nature of ‘omics work, each investigator is well-versed in the skills needed to manage and mine very large datasets. Further, one can easily have confidence that the investigators involved in the NC1170 project will be at the forefront of development and application of new technologies during the next five-year project. 

The advantages for doing the work as a multistate effort.

Using advanced technologies to genetically improve poultry is an inherently interdisciplinary effort that requires expertise from multiple domains. A multistate effort is an ideal vehicle to bring together principal investigators who can contribute the needed knowledge from various disciplines to tackle a challenge as complex as improving poultry production. NC1170 brings together geneticists, genome biologists, bioinformaticians, physiologists, immunologists, nutritionists, etc. in a way that would be very difficult to achieve in the absence of a multistate group. Moreover, it creates opportunities for the group at large to interact and exchange information with stakeholders, so that the research efforts can be aligned with needs of the industry. In effect, the NC1170 project is a sophisticated research tool that enables a systems level approach to improvement of poultry that would be very difficult to achieve in the absence of the multistate mechanism. New goals of the industry can be more effectively addressed by the combination of resources available by the NC1170 team approach. The NC1170 researchers possess an exciting combination of expertise to create and contribute new tools and knowledge to apply to poultry improvement. And the ability to meet, interact, and share information and resources fosters an environment for multidisciplinary interactions needed to address the complex biological questions facing researchers today.

What the likely impacts will be from successfully completing the work.

The poultry industry will likely face new and potentially more complex challenges to its ability to continue to supply the world with an affordable source of complete protein during the period covered by this proposal. It is expected that the work of the NC1170 will continue to help the industry to combat these challenges by contributing new knowledge that can be used to enhance breeding strategies and management systems. These new strategies can in turn be applied to improve growth, development, immunity, and physiology, and to maintain the economic and environmental sustainability of the industry. In addition to these translational impacts, completion of this work will make a major contribution of new, fundmental knowledge about avian genomes, including their similarities and differences, that will be valuable to the scientific community at large.  Ultimately, completion of this work will support the production of an affordable, safe, and nutritious source of complete protein for the global population, while markedly advancing understanding of genome-to-phenome relationships in poultry.

Below we describe by objective the major accomplishments achieved by the NC1170 Multistate Research Project covering 2018 to the summer of 2022. Achievements included the application of next generation sequencing technologies to improving poultry genomes and numerous contributions to advances in bioinformatics, annotation, and transcriptomics as applied to fundamental disciplines in poultry biology. Our work is conducted under the auspices of many collaborative arrangements and with stakeholders in the allied poultry industries for the purpose of improving poultry production. The scholarly publications resulting from this project (see appendix) includes over 300 articles in peer-reviewed journals, books and proceedings. Special note should be made of the large number of publications involving collaboration among members of this Project as well as international researchers.

Objective 1: Create and share data and technology to enhance the development and application of genomics, epigenomics, and systems biology in poultry.

With the development of high-throughput deep sequencing and the applications of start-of-art modern biotechnologies in the post-genomic era, NC1170 participants have achieved tremendous success in understanding poultry genetics, genomics, and biology, which further fosters collaborations and avoids duplication of effort.

ADOL and AZ invested significant effort into improving the quality and annotation of the chicken genome, which is critical for the efforts of members of NC1170. This work included release of a new chicken reference genome, GRCg6a, that improved the assembly based on the Red Jungle Fowl. More recently, new references assemblies were generated based on a commercial layer (bGalGal1.pat.whiteleghornlayer.GRCg7w) and a commercial broiler (bGalGal1.mat.broiler.GRCg7b). These reference assemblies have resulted in a marked increase in the number of transcripts identified in the chicken genome and new annotations of various regions of the genome.  AZ provided standardized chicken gene nomenclature for GRCg7 broiler and leghorn annotations to support comparative studies, and annotations to support functional genomics analysis of poultry data sets. A workflow for predicting function of novel ncRNAs was also developed by AZ.

CA advanced the use of the chicken genome by functionally annotating regulatory elements across multiple tissues. These data, which are shared with the community, support efforts of multiple investigators to identify potential causative variants for economically important traits. These sets of eQTL are a valuable resource for deciphering the genetic and biological basis of complex traits in chickens.

Several groups created and shared data that are being used to understand that genetic basis for susceptibility to various infectious diseases in poultry. As part of efforts to use the genome to combat Marek’s disease (MD), a highly contagious and deadly viral disease of poultry, ADOL generated assemblies of the T cell receptor (TCR) locus for two chicken lines that differ in genetic resistance to the causative virus. ADOL also used single-cell RNA sequencing to define chicken immune cell types and their accompanying response to Marek’s disease virus (MDV) infection. WU focused on functional annotation of genes that are relevant to immune function in chickens. The transcriptomes of 20 immune cell and tissue types were defined using RNA seq, including characterizing the repertoire of lncRNA in each cell or tissue type. WU also utilized both ATAC-seq and CHiP-seq to analyze the epigenomes of each source. This effort included optimization of a new methodology (Cut and Tag). Data collection is nearly complete and data analysis is ongoing. CA also contributed to the study of the epigenome by developing and enhancing methods for ChIP-seq and ATAC-seq across tissues for use by the poultry genome community. MI used chemical proteomics approaches to annotate catalytically active kinases and deubiquitinases from chicken liver and spleen, both of which are relevant to pathogenesis of infectious disease. Machine learning and deep learning approaches were also used to identify farm practice variables that contribute to pathogen prevalence and multidrug resistance in pastured poultry.

Other valuable datasets were generated and shared by investigators working under Objective 1. TX created and shared (on pubic repositories) multiple whole genome, transcriptomic, and microbiome datasets that enhance the application of the systems approach in poultry. NC worked at the intersection of genetics and the environment by evaluating different genetic strains of layer hens, and how unique genetic features of each strain facilitated adaptation to various production housing systems.

Objective 2: Facilitate the creation and sharing of poultry research populations and the collection and analysis of relevant new phenotypes including those produced by gene transfer.

Given the high scientific value of characterized chicken lines in the genomic era and the significant costs required to maintain live flocks, NC1170 participants have been very proactive in sharing birds and derived materials and information, which further fosters collaborations and avoids duplication of effort. ADOL, IA, and CA each maintained and shared numerous lines of various types (e.g., inbred, congenic) for use in a range of genetic and disease model studies.

ADOL maintains a large number of highly inbred or closed chicken lines that are characterized for a number of traits, especially those associated with viral diseases, including maintenance under specific pathogen free (SPF) conditions. Besides providing unique genetic resources to our location, ~1,500 embryos or chicks are supplied yearly to academic institutions or companies in the United States, e.g., line 6x7 F1 birds were the primary individuals characterized by CA in their chicken annotation efforts. IA maintained chicken genetics research lines (including highly inbred, MHC-congenic, and closed populations; and advanced intercross lines) which are used and distributed as the biological discovery platform for research at IA, by collaborators in NC-1170 and others, e.g. ADOL, COH, DE, VT, and CA. Studies of these lines identified genomic regions, genes, and genetic networks of economic importance.

CA maintained and shared chicken genetic stocks (inbred, congenic inbred, and mutant) of specific genotypes expressing unique disease-related or developmental phenotypes. Highly inbred lines that differ in disease response to viral infection were sequenced to help understand the underlying genetic basis. Additionally, regulatory elements (e.g., enhancers, promoters, insulators) were functionally annotated in a number of lines.

COH evaluated MHC-Y haplotypes segregating in experimental inbred and highly-selected lines, e.g., Fayoumi and White Leghorn lines from IA, and high and low antibody selected lines from VA. Investigation has demonstrated a relationship between certain MHC-Y haplotypes and immune responses

TX maintained a Red Junglefowl population of the Richardson strain. This well documented research population has become a key resource to look at the developmental biology of morphological traits in chicken. Additionally, a RJF x Silver Sebright cross is being used to map feathering and pigmentation traits.

Objective 3: Elucidate genetic mechanisms that underlie economic traits and develop new methods to apply that knowledge to poultry breeding practices.

The ability to utilize poultry genomes and their encoded information to maintain healthy, profitable and sustainable production is critical for the poultry industry. Members of NC1170 are vested in using their expertise to identify new ways to prevent disease, enhance growth, and promote welfare and wellbeing through genetic improvements. Accordingly, a range of physiological conditions and phenotypic traits have been intensively studied as part of Objective 3.

Disease susceptibility and infection.

ADOL determined that somatic mutations are required in addition to Marek’s disease virus (MDV) infection for virulent MDV to induce tumors. Ikaros was identified and validated as a major cancer driver gene for MD. ADOL also investigated the roles of T cell receptor (TCR) genes and usage in response to MDV infection. UM characterized copy number variations and epigenome modifications associated with the resistance to MD using next-generation sequencing.

WU elucidated molecular mechanisms of differences in in disease resistance and susceptibility in chicken lines with different MHC-B haplotypes. Several potential causative differences were found, including that more effective macrophage responses were found to underlie enhanced disease resistance in B2/B2 vs. B19/B19 lines. WU also investigated the role of epigenetic responses to viral infections, and genetic variation in the immune response to avian coronavirus. CSU identified MHC haplotypes in breeder silkie populations.

AR successfully developed a new hybrid model to induce bacterial chondronecrosis with osteomyelitis (BCO) and lameness in broiler chickens. The new model induces lameness up to 70-80% in birds raised on litter flooring. This model was used to identify a prebiotic that reduces the incidence of BCO lameness. AR also advanced understanding of genetic factors that increase the incidence and severity of ascites, a deadly consequence of pulmonary hypertension in broiler chickens. This work demonstrated that the genetics of ascites are intimately dependent on specific genetic background, which lays the groundwork for follow-on studies.

MN investigated the response to aflatoxin exposure by characterizing the transcriptome level changes in the liver, intestine and spleen of birds exposed to AFB1. RNAseq datasets produced from this work were shared publicly.

Susceptibility to stress and the environment

IA characterized genetic variation in commercial, research, and global indigenous chicken populations in collaboration with CA. This work identified genomic regions and candidate genes associated with response to heat stress, and to bacterial and viral infections in chickens. It also identified gene expression responses associated with body composition, heat stress, and disease status. CA in collaboration with IA, developed a low-density panel associated with resistance to heat stress and Newcastle disease virus infection that can be used to breed more resilient chickens in adaption to hot climates in developing countries and improved knowledge of genes associated with an enhanced immune response may inform further information on vaccine efficacy in poultry production. IA determined gene expression responses associated with body composition, heat stress, and disease status.

UG identified highly deleterious alleles that are more frequent in recent inbreeding, revealed that heat stress limits the reproductive capacity of Eimeria maxima in broiler chickens, Eimeria acervulina infection alters lipid absorption and utilization, and genomic matrix should evolve from a measure of realized additive relationships to an optimum measure of genetic similarities between individuals.

AR identified genes associated with the stress response of birds and identified an additional component of the functional stress axis. AR also used whole genome resequencing to identify copy number variants that diverge between high stress and low stress lines of quail.

Growth, development, and muscle myopathies

MD used cell and molecular technologies to define the mechanisms underlying pituitary development and cell differentiation, and to identify genes and gene networks involved in neuroendocrine (hypothalamic and pituitary) control of growth, development, and body composition in broiler chickens. TN incorporated transcriptomics and metabolomics to understand the mechanisms through which the broiler breeder hen diet can be used to developmentally program body composition in offspring. MI identified Death-associated protein (DAP) that would likely negatively affect muscle development, discovered circular RNAs are differentially expressed with temperature changes and among genetic lines, and found growth selection resulting in large muscle fibers may lead to hypoxia which may lead to altered glucose metabolism, cellular detoxification, and muscle degeneration.

AR identified miRNAs associated with broiler breast muscle myopathies. Small molecule and lipid metabolite biomarkers of myopathies were also identified through a combination of metabolomic and lipidomic profiling of blood from affected and unaffected broilers. In collaboration with DE, AR identified specific signaling pathways associated with muscle growth and determined that phytase supplementation was significantly reduced woody breast. DE identified promising candidate genes and circulating biomarkers for Wooden Breast and White Striping in modern broilers, developed a new tool (VADT; https://github.com/mjtiv/VADT) for the detection of allele-specific expression (ASE) from RNA-seq data, and characterized molecular and morphological changes in the breast muscle of modern broiler chickens over the growth period and in respect to the onset and development of Wooden Breast and White Striping.

TX used WGS and optical mapping to identify genome structural variants associated with metabolic disorders in fast-growth broilers. MN, in collaboration with MI and OR, quantified climate change impacts on poultry breast muscle growth and development, morphological structure, intramuscular fat deposition, and protein functionality to develop appropriate strategies to mitigate the undesirable changes in meat quality. CSU assessed mitochondrial DNA concentration in broiler chickens with woody breast.

Gut health and the gut microbiome

MN advanced the understanding of interactions between the turkey gastrointestinal microbiome and host during maturation and microbiome modulation. TX developed new knowledge to enhance commercially important traits (breast meat quality, early life microbiome assembly, early life immune responses), which are helping improve breeding and management practices in poultry. They showed the role of lighting in influencing gut microbiome assembly.

Poultry production

CU used RNAseq to investigate the molecular basis for declining productivity with age in laying hens. Upstream regulator analysis revealed the estrogen receptor as a predicted upstream regulator of laying persistence. UM characterized hypothalamic, pituitary, and ovarian tissue transcriptomes in turkey hens with high and low egg production rates. PA studied the expression of genes related to steroidogenesis, such as FSHR, STAR, CYP11A1, HSD3B, and progesterone secretion was significantly decreased in response to metformin treatment in a dose-dependent manner in broiler breeders. WI in collaboration with UM, evaluated the effect of Se deficiency and high dietary Se on tissue Se and selenoenzyme activity in turkeys to better define Se requirements and safe upper limits for dietary Se supplementation

WI used deep learning to predict complex traits in broilers by utilizing genomic information, assessed current trends of local chicken breeding and factors that influence their production performance in Benin, Africa, and developed a QTL-directed dependency graph mapping approach to investigate potential causal phenotypic networks for egg traits in an F2 chicken population. IA Developed and evaluated strategies for the implementation of genomics in poultry breeding programs.

Objectives

1. Create and share data and technology to enhance the development and application of genomics and systems biology in poultry.
   
2. Facilitate the creation and sharing of poultry research populations and the collection and analysis of relevant new phenotypes including those produced by gene transfer.
   
3. Elucidate genetic mechanisms that underlie economically important traits, including genetic variants and functional regulatory elements within the genomes of poultry species, and develop new methods to apply that knowledge to poultry breeding practices.
   

Methods

Objective 1. Create and share data and technology to enhance the development and application of genomics, epigenomics, and systems biology in poultry.

Objective 1 will collect and disseminate both data and methods to improve our understanding of the interaction between the genome and the environment. Environment encompasses all levels including the nucleus, cell, tissue, organism and external environment. Ultimately, it is the combination of the genome and environment that gives rise to the phenotypes important to poultry production. Systems biology approaches will be applied to model and integrate data across these various levels to improve our ability to apply genomic understanding to improving poultry production. Advanced data mining methods (e.g., machine learning) will be applied to extract patterns from the ever-growing scope of data, made by possible by continual advances in ‘omics methods and platforms. The new reference assemblies of the chicken genome will be fully annotated, which will augment work by all members of NC1170. Advanced DNA sequencing platforms and tools to mine transcriptomes and epigenomes at the single cell level will be fully utilized to maintain the cutting-edge nature of the work done by NC1170. Other ‘omics tools – e.g., metabolomics, lipidomics, proteomics – will be enlisted to collect additional large and complementary data sets. Where possible, these tools will be applied to novel lines and genetic models created and or maintained by members of this group.

ADOL will continue to improve the chicken genome assembly, including aiding the development of a pan-genome and assemblies of various MHC and TCR haplotypes, and aid in annotation efforts, especially concerning identifying full-length transcripts, alternative transcription start sites (TSS) or splicing events, RNA methylation or editing, associated proteins, etc.; and will develop biomarkers for specific immune cell populations. Meanwhile, ADOL will aid in developing chicken cell lines for tissues of interest, e.g., muscle and fat.

CA will aid in improving the chicken genome assembly, including assemblies of various MHC and TCR haplotypes, and annotate and validate regulatory elements in vitro in developing high-throughput technology. CA will also develop iCRISPR and aCRISPR cell lines to evaluate the functions of regulatory elements in DF-1 and muscle cell lines.

AZ will create and share data and technology to enhance the development and application of genomics, epigenomics, and systems biology in poultry, provide predicted functional annotations for novel mRNAs and ncRNAs identified by FAANG and related projects, and continue to develop standardized chicken gene nomenclature, focusing on genes specific to chicken & on supporting gene nomenclature in other poultry species.

TX will continue the creation and dissemination of new assays and datasets, particularly focusing on broiler and broiler breeder performance.

NC will evaluate the array of gene expressions (stress, nutrient absorption, immune response) that can be altered by a different housing density in layers hens, and correlate gene expression in different thicknesses with layers hen’s production, health status, and welfare.

MI will apply machine learning and deep learning approaches to mine microbiome data beyond diversity metrics to identify microbiome signatures that predict pathogen prevalence in poultry meat.

WU will continue to share data on cis-regulatory elements in chicken tissues and immune cells and build enhancer maps using Hi-C and will also create single-cell data for chicken tissues of economic importance.

OR will elucidate the molecular and cellular mechanisms of intestinal immune responses to enteric diseases in chickens by performing RNA-seq and/or scRNA-seq on sorted immune cells that confer protection to enteric diseases (coccidiosis and necrotic enteritis). The metabolic role of intraepithelial lymphocytes in the progression of wooden breast syndrome in broilers will also be investigated.

Objective 2. Facilitate the creation and sharing of poultry research populations and the collection and analysis of relevant new phenotypes including those produced by gene editing

We will achieve this objective by maintenance and development of specialized poultry populations, cell lines and resources for researchers to effectively investigate key production traits. We support the creation, sharing and phenotyping of genetic material (e.g., chicks, fertile eggs, blood, tissue, DNA or RNA) for collaborative studies. This includes the maintenance or development of avian cell lines to support in vitro studies, as well as resources for in vivo research.

Our approach is to identify both in vivo and in vitro resources that serve as tools for identifying the causal agents for economically important traits. Poultry lines and populations include (but are not limited to) inbred lines, congenic lines and advanced intercross lines that are genotyped for relevant traits and phenotypes, as well as pathogen-free populations. We also support the development and maintenance of avian resources for furthering in vitro studies. These studies may include (but are not limited to) investigating molecular mechanisms underlying important production traits, understanding how gene expression is regulated to produce observed phenotypes and determining function of genetic elements that contribute to traits and phenotypes. Resources to support mechanistic and functional in vitro or in ovo studies include the development of cell lines, and technologies for creating transgenics and mutants (e.g., gene delivery, over-expression, knock downs and targeted mutagenesis).

ADOL will maintain and distribute to NC1170 collaborators and more, a large number of highly inbred or closed chicken lines that are characterized for a number of traits, especially those associated with viral diseases, including maintenance under specific pathogen free (SPF) conditions. Efforts are already planned to use one or more of these lines for genomic modification via CRISPR by collaborators at PGRU.

IA will maintain and share genetic material from unique chicken research lines (including diverse, highly inbred lines; MHC-congenic lines; and highly advanced intercross lines of more than 30 generations of intercrossing) as resources for identifying genes, genomic regions, and genetic networks of economic importance.

NC will create a Red Junglefowl flock as a source of genetic material to study the evolution of gut health in poultry and the genetic markers. TX will continue to maintain a Red Junglefowl population (Richardson Strain) and provide access to live birds as well as tissues to the community of poultry scientists and broader avian biologists.

CA will maintain 16 chicken lines with special genetic characteristics for muscle dystrophy, other mutations or viral susceptibility that will be shared with NC1170 groups and other outside collaborators.

Objective 3. Elucidate genetic mechanisms that underlie economically important traits (genotype to phenotype) including genetic variants and functional regulatory elements within the genomes of poultry species, and develop new methods to apply that knowledge to poultry breeding practices.

Objective 3 will address the mechanistic underpinnings of production-relevant traits by applying advanced ‘omics tools and data mining methods to further understand growth, development, performance, and disease-resistance in poultry. We will use both well-established genomic methods (e.g., whole genome RNAseq, proteomics) as well as newly established and emerging methods (e.g., single-cell RNAseq, spatial transcriptomics) in combination with key animal resources (stem cells, inbred research lines, commercial lines, and exotic ecotypes). 

Disease susceptibility and infection.

ADOL will study the molecular basis for genetic resistance to MD, identify specific alleles in cancer driver genes associated with MD genetic resistance, determine if MD genetic resistance and/or MD vaccines contribute to MDV evolution to higher virulence, and determine if there is MHC or non-MHC genetic resistance to infectious bursal disease (IBD) or infectious laryngotracheitis (ILT). CA will collaborate with IA and ADOL to determine the molecular basis for genetic resistance to NDV and AIV, and determine the roles of functional regulatory elements in regulating immune response and disease resistance. UM will explore the mechanisms and epigenetic modifications in chicken immune CD4+ T during MDV infection, anticipating discovering key regulator factors and targets in MD resistance.

WU will evaluate the role of CHIR in disease resistance, investigate KIR in chicken reproduction, investigate epigenetics of viral infection in chickens with different genetic backgrounds, and determine the effect of trained immunity on disease resistance in different chicken lines. CS will evaluate MHC haplotypes association with Northern Fowl Mite infestation in laying hens. OR will elucidate the molecular and cellular mechanisms of intestinal immune responses to enteric diseases in chickens using RNA-seq and/or scRNA-seq on sorted immune cells that confer protection to enteric diseases (coccidiosis and necrotic enteritis). AR will continue to work on BCO and lameness.

Susceptibility to stress and the environment

IA will identify genetic determinants of host response of chickens to biotic and abiotic stressors. AR will continue to work on the neuroendocrine regulation of stress. GA will focus on adaptation to heat stress and water needs, including elucidating the molecular basis for variation in water needs. Genetic influences on protein deposition and feed efficiency under heat stress will also be investigated.

Growth, development, and muscle myopathies

OR will investigate the metabolic role of intraepithelial lymphocytes in the progression of wooden breast syndrome in broilers. AR will continue to work on breast muscle and myopathies, including woody breast. DE will study spatial transcriptomics of the breast muscle at the single-cell level, identify causal genes for Wooden Breast and White Striping in modern broilers, and study systemic lipid metabolism and anomalies in vasculature.

UMN will continue to work on poultry breast muscle growth and development, in collaboration with MI and OR, to develop strategies to mitigate undesirable changes in meat quality. CA will collaborate with IA and ADOL to identify potential causative variants associated with growth rate and feed efficiency, and determine the roles of functional regulatory elements in regulating immune response growth-related complex traits.

UM will investigate the critical regulatory factors in chicken embryonic development. UM will also perform RNAseq and single-cell RNAseq on tissues from turkeys and chickens, to define the mechanisms regulating reproduction in turkeys and growth and body composition in broiler chickens. WI will investigate the feeding behavior of broilers and its relationship with feed efficiency and production traits; develop predictive models for the detection of more efficient animals, and estimate genetic parameters (e.g., heritability and genetic correlations) for feeding behavior and feed efficiency in broilers. TN will focus on extracting the transcriptomic and epigenomic mechanisms thorough which the hen diet alters body composition in broilers. 

Gut health and the gut microbiome

NC will investigate gene expression alterations correlated with nutrient absorption, inflammatory gut response, and immune response in broiler breeders under alternative feed program during the early development, and egg production phase.

Poultry production

IA will develop and evaluate strategies for implementing genomics in poultry breeding programs. NC will evaluate the transgenerational (epigenetic) effect of broiler breeders alternative feed program on the progeny. TX plans to continue working on broiler breeder issues, including reproductive performance, immune maturation, and microbiome modulation.

PA will determine the extent to which metformin and PPAR-gamma agonists affect hepatic lipogenesis and yolk precursor synthesis, estrogen receptor signaling in the liver and in hepatocytes, and determine the appropriate feed level and metformin treatment duration to maximize fertile egg production from broiler breeder hens.

Technical Committee (TC) members will publish NC1170-project-generated data in the peer reviewed literature, thus making content accessible to the scientific community. In addition, members participate in conferences and workshops (e.g., Poultry Science annual meeting, National Breeders Roundtable, International Plant and Animal Genome annual meeting, and many disciplinary or technology-related meetings) providing oral presentations of results and proceedings (written communications). Most conference and workshop environments welcome stakeholder participation and interaction. In addition, committee members frequently provide seminars on their work at other academic institutions and companies. Those conducting genome sequencing and analysis deposit their results in relevant federally-funded databases allowing access by the scientific community and stakeholders. Several NC1170 members also participate in other multistate research projects (e.g., NE1834) allowing for cross-fertilization of techniques and relevant content. Several members are organizers of databases as part of their project efforts and ensure dissemination of NC1170 data, tools and content.

 

Organization/Governance

The organization and planning of the NC1170 Project are the responsibility of the Technical Committee (TC) members consisting of scientists from land-grant or non-land grant research institutions, the USDA-ARS, and industry. Administrative guidance will be provided by an assigned Administrative Advisor and a USDA-NIFA Representative. Voting membership shall consist of the TC members; only one member representing each participating agency shall be eligible to vote. Our governance includes a two-year term for a Chair and a Secretary. An executive committee of Chair, Secretary and immediate past-Chair (if needed) coordinate business between meetings. Volunteer members of the TC organize objective content for necessary reports. Members are expected to write and distribute annual reports to the Technical Committee and administrators through NIMSS prior to each annual meeting. In addition, members affiliated with agriculture experiment stations submit results to NIFA through NRS, NIFA’s Reporting System. Members are expected to attend annual meetings at least three of five years. Attendees at meetings can include emeritus members, collaborating scientists, invited colleagues, scientists interested in the topical areas discussed.
