Administrative Advisors Report: Ramesh Kanwar, Administrative Advisor to the NCERA-101, addressed the meeting with his Administrative Advisors Report. Ramesh noted that registration for this meeting is 150 people, from the USA, Canada, the UK, Australia, Japan and other countries. The committee structure consists of collaboration by all members, with other contacts and strong industry support. The presentations at this meeting are impressive. For example, the Australian presenters indicated funding of $40M for facilities, and $4M + funding for staff. The committee is very successful and has a high impact. It is also well placed for the future. Older members, Ted Tibbitts, Bob Langhans and others, remain active and provide valuable training for newer members. In the 10 years that Ramesh Kanwar has been administrative advisor, we have met at a new location every year. Dr. Kanwar reminded group that the committee had a number of milestones to meet which included that the annual report and impact statement to be posted on the NCRA website within 60 days, that we are at the midterm review is on a 5 year and that an impact statement is needed. He noted that the impact statements are different from last year and passed out examples. Ramesh Kanwar emphasized the importance of international cooperation and stated, We have started a tradition in this group to travel overseas every 4 to 5 years. Dont lose this tradition. In the past we have met in the UK and in Australia. CSREES Representative Report: Daniel Schmoldt, National Project Leader, Plant and Animal Systems, reported that CSREES funding saw a 0.75% increase before a 0.7% across the board rescission, to $1,198.8M. NRI (the USDA National Research Initiative) is funded to $ 190.8M. Up to 26% of NRI funds can be used for integrated projects. NRI bio based products program will have increased funding. Congressional earmarks are back  probably more, but with 25% reduction in funds from 2006. Bio energy and bio based products are up. Dr. Schmoldt noted that Farm bill legislation expired at the end of last year, but has been extended to March 15. Dr. Schmoldt provided links to the draft language of the Farm Bill and the Specialty crop initiative and encouraged members to be active in promoting the value of there work. Approval of 2007 Meeting Minutes: Gary Stutte and Mark Romer presented the Minutes of the 2007 meeting in Tuskegee. The members recognized Mark Romers work on behalf of the committee, which goes far beyond his role as Membership Secretary. Gary Stutte reported that full copy of the 2007 Meeting Minutes are posted on the NCERA 101 webpage and that the Annual report and summary minutes are posted on the USDA website (http://www.nimss.umd.edu/homepages/saes.cfm?trackID=7936). Motion to accept the Minutes of the 2007 meeting in Tuskegee: Bruce Bugbee. Seconded: Ron Lacey. All were in favor. Membership and Website Report: Mark Romer reported that there is no real change in the total number of members. Current membership is posted on the website (http://ncr101.montana.edu/members.htm). Ted Tibbitts has updated the website and modifications will be posted soon. Mark also noted that the group is now 33 years old. Bruce Bugbee raised a question about universities and states that were active in controlled environment research, but not active in the committee. . Bruce Bugbee moved that a form letter be written, inviting participation in the NCERA-101, signed by the committee chair of the committee. Members were also encouraged to approach individuals and institutions that are presently not represented. Ramesh Kanwar commented that the model of this committee is to encourage the participation of the private sector in public/private partnerships. Membership Awards: Since 2002, the contributions of selected members have been recognized by the group during the annual meeting. This year, Bruce Bugbee (Utah State University) and Ray Wheeler (Kennedy Space Center) were presented with the 20 Year Member Award while Dave Tremmel (Duke University) and L.D. Incoll (Leeds University, UK) received the Significant Contributor Award. NCERA-101 awards are documented on the group website at http://ncr101.montana.edu/awards.htm Email Discussion Group Mark Romer revisited the proposal from 2007 of forming an E-mail forum (discussion group). This was not discussed at length due to time limitations. Instrument Package Report. Bruce Bugbee announced the poster on the instrument package and handed out copies. The instrument package circulates among the members and it could be sent to our international members in the UK or Australia. It contains (among other instruments), the following: Photosynthetic radiation calibration package, Net radiometer (Eppley), Spectroradiometer, Humidity package for calibrating humidity instruments. It was strongly suggested that experiment station directors be approached to support the use of this instrument package on their stations. International Committee on Controlled Environment Guidelines (ICCEG) report: A.J. Both reported on activities a subcommittee of the ICCEG (International Committee on Controlled Environment Guidelines), namely the Tissue Culture Guidelines subcommittee He distributed advance copies of the Tissue Culture Guidelines (Guidelines for Measuring and Reporting Environmental Parameters for Experiments in Plant Tissue Culture Facilities) brochure, and requested support and funding to print and distribute 5000 copies for NCERA-101. The Tissue Culture Guidelines will also be posted on the committee website (http://ncr101.montana.edu/Guidelines/TC-guidelines.htm ). Proposal to Translate Growth Chamber Handbook: Lynton Incoll gave a report on the offer from Miguel Gimenez, a member of the UK CEUG from Spain, to translate the Plant Growth Chamber Handbook into Spanish. (http://ncr101.montana.edu/Growth_Chamber_Handbook/Plant_Growth_Chamber_Handbook.htm ) There was extended discussion on the extent of proposal, copyright issues, and distribution. A motion was made to refer this to back to the executive committee and continue the discussions with Miguel Gimenez. Posting of Meeting Presentations: After some discussion, Gary Stutte agreed to link the presentations to the Meeting program. Presenters would be given the opportunity to decline the posting, or to remove sensitive information prior to providing web access. New business: Committee Officers: New business began with the selection of the 2008  2009 Incoming Secretary. The nominating committee consisted of Erik Runkle, Gary Stutte and Alex Turkewitsch. The nominating committee nominated Jonathan Frantz, who has accepted the nomination. The nominating committee requested additional nominations from the membership. Ted Tibbitts moved that nominations be closed. Bruce Bugbee seconded. All were in favor. Jonathan Frantz was acclaimed Incoming Secretary of the NCERA-101. Hosting of 2009 Annual Meeting: Bruce Bugbee and Utah State University accepted the committees invitation to host the 2009 Meeting of the NCERA-101. The meeting is to be held at Park City, UT. If we wish to have the meeting in March as usual, this coincides with the end of the ski season and hotel rates are at a minimum $200 per night. In April, the hotel rates change to $150. Mid March is OK for most members, and available dates are 7  11 March 2009 or 14  18 March 2009. General consensus was that the 2009 meeting should be held 14  18 March 2009.

NCERA 101 Accomplishments (Complete station reports can be viewed at http://ncr101.montana.edu/station_reports.htm#2008) Agritechnove has completed the design of several projects, including the USDA Ithaca and Geneva facilities, Bayer CropSciences High-Containment and Low-Containment greenhouses, the new USDA Agricultural Research Technology Center in Salinas, CA. The Biotron at University of Western Ontario opened with the 6 high-tech biomes on the roof and a new BSL-3 rooftop greenhouse for University of Florida, Gainesville is on the drafting board. Agritechnove also began the design of a large rooftop facility for Dartmouth College, NH. Design is scheduled for completion early next year. Agritechnove joined the large A/E team responsible for the design of the new King Abdullah University of Science and Technology in Saudi Arabia. University of Alaska has evaluated a number of different plastics for use in high tunnel production and evaluated effects on productivity at high latitudes. They have developed strategies for lowering the temperature of the nutrient solution as an effective approach to temperature control and local greenhouse strategy for continuous high rate of hydroponic lettuce production. In short season locations, these systems are especially valuable as a wider range of locally produced crops can be offered without competing with traditionally available produce. U. Alaska is evaluating the use of geothermal and other alternatives to fossil fuels to power controlled environment facilities. The approach developed in collaboration with Chena Hot Springs Resort to use geothermal or other alternative energy for greenhouse and controlled environment production is adaptable and suitable for rural communities of various sizes in Alaska and other remote areas. University of Arizona has enhanced their facilities with upgrades to the ebb and flow benches for lettuce production, high output LED lighting units and designation of a BSL-lab for performing transgenic research. U. Arizona offered a Greenhouse Crop Production and Engineering Design Short Course and has completed studies on the effects of EC on productivity and lycopene content on lettuce. In addition, a hydroponic plant growth facility for producing fresh vegetables at the South Pole Station, Antarctica was completed. Duke University has completed a major upgrade to facilities and is high demand to support growth of Arabidopsis plants. Research performed within the Duke Phytotron by agricultural biotechnology companies have identified over 60 new Bt genes, identified genes associated with root architecture and are developing low N corn genotypes. University of Georgia has acquired soil moisture sensors and a wireless datalogger which are being used to quantify the daily water use of bedding plants. They are finding that water use is much lower than anticipated. They have also found that application of abscisic acid (ABA) has the potential to reduce water loss and increase the window of marketability. They have identified, and are researching, dose-dependent issues associated with ABA usage. University of Guelph has installed eight computer controlled growth chamber systems which allow temperature control from -20 to +40 C and irradiance from complete darkness to 80% full sun. U. Guelph has found that direct root zone application on aqueous ozone can reduce the incidence of root pathogens and holds promise as an environmentally sound strategy for controlling Marchantia polymorpha (Liverwort) in nurseries and greenhouses. U. Guelph collaborated with NASA-KSC and evaluated the effects of hypobaric conditions on wheat, lettuce and radish. Two natural products that are early photosynthates of snapdragon were identified, and a possible role in insect and pest defense determined. University of Maryland completed construction of their new Biosciences building (http://chemlife.umd.edu/biosciencebuilding/), which opened on September 18, 2007. A new controlled environment facility was incorporated as part of 68,000 square feet of flexible laboratory space. The building is equipped with two Biosafety Level-3 labs, which enable researchers to safely work with pathogens, the microorganisms that cause disease. Other resources include a 475-seat lecture hall and eight conference rooms for teaching and professional meetings. In addition to the Biosciences building, a number of upgrades to the greenhouse facilities have been made to improve water use efficiency. There are 33 faculty-led research groups in Plant Science and Landscape Architecture, Entomology, and Cell Biology and Molecular Genetics that have active projects in the facility. Michigan State University continues to upgrade its growth chamber capacity and currently has 141 growth chambers in operation. It will be implementing remote access for many of the newer chambers. Michigan State University expanded and formally released the Greenhouse Energy Cost Reduction Strategies website (www.hrt.msu.edu/Energy/Notebook.htm). This website includes pertinent research-based information on how greenhouse growers in temperate climates can consume less energy and improve production efficiency. This resource includes documents on greenhouse lighting (15), temperature and scheduling (12), energy-saving technologies (20), alternative fuels (18), and energy grant and loan opportunities (9). Testing of environmental management systems to regulate flowering through limited inductive photoperiod and temperature management of several ornamental species holds promise for significant reductions in energy costs and reduced production time. NASA-Kennedy Space Center enhanced their capabilities by modifying an M-48 to have zero-humidity air input (via facility installed desiccant dryer) as a method of dropping chamber relative humiditys to as low as 10%, added capability of the CEL to perform Biosafety level 1P GMO plant research studies and completed construction of a Low Pressure Test bed (LPT) that provides a capability for maintaining atmospheric pressure, temperature, and relative humidity for a variety of testing applications. Testing and use of a new high output LED array from ORBITEC with >300 ¼mol m-2 s-1 PPF @ each of six wavelengths (400, 440, 520, 640, 660, and 720 nm) was continued in two VEGGIE units (Phase II SBIR grant from NASA) as a deployable plant growth system for producing salad type crops. The Lighting Testbed was enhanced with the addition of a 1 m integrating sphere and an Optronics spectroradiometer with spectral range in the visible and near IR (380 to 1180nm). North Carolina State University Phytotron continues to be in high demand and operational in 2007 at 96% of the recommended optimal occupancy, or 79% of maximal occupancy. Faculty and students from 10 departments in the Colleges of Agriculture and Life Sciences, and Forestry conducted 87 different projects in the Phytotron during 2007. These supported work with Arabidopsis, agronomic and horticultural crops. ORBITEC has competed one LED growth room with a 60 square foot red/blue LED array divided into four sub arrays, each containing three light control zones. The arrays are water cooled so they remain near room temperature and can be operated very close to the plant canopy. Light level and red/blue ratio for each of the 12 lighting zones can be independently controlled. The room also provides control of photoperiod, temperature, humidity, and carbon dioxide levels and was designed for operation up to Biosafety Level 2P. Two additional rooms with similar capabilities are nearing completion. To date, tobacco (3 types), corn, lettuce, dwarf rice, and dwarf tomatoes have been successfully grown in this room. ORBITEC had two small plant growth units (Astro Gardens") included in the Education Payload Operations (EPO) Kit C that was flown on STS-118 to the International Space Station in August of 2007. Purdue University has completed all projects associated with the tenth anniversary of moving the facility. The enhancements include: replacing evaporative pads with ones improved with an exterior coating; replacing motorized shade-curtain fabric with improved material; plumbing acid injection equipment to our clear water supply to neutralize alkalinity. Work continues on the development of HELIAC LED lighting system, developed in conjunction with ORBITEC to provide intercanopy lighting to cowpea, tomato and sweet potato. Environmental management and cultivar testing has been undertaken to reduce the energy costs associated with poinsettia production. A closed-loop underground water-recirculating system is being installed that will provide bottom heating to a high tunnel production system. The high tunnel system will be constructed in the coming year and provide a proof of concept for off-season production of specialty crops. Rutgers University been actively developing and communicating information on greenhouse energy conservation. These include installing a new landfill gas fired 250 kW microturbine at the EcoComplex greenhouse facility, refining a greenhouse environment control simulation tool (spreadsheet) that allows the evaluation of control strategies including heat pumps and energy storage facilities, and completing a bioenergy assessment report for the state of New Jersey. The Bioenergy Assessment will be used to identify future research opportunities, as well as provide valuable information for New Jerseys bioenergy master plan. Texas A&M University continues to maintain and operate the low pressure plant growth (LPPG) system, which consists of six chambers capable of controlling atmospheric composition at hypobaric pressures. These chambers have been used to characterize the effects of hypobaria on ethylene production and yield of lettuce, with particular attention to space applications. A new project to design and develop a microalgal growth test bed for the production of biodiesel has been started. Utah State University is currently working on a number projects including MicroGravity Root-zone research to improve the physical characteristics and nutritional status of the root-zone media for the closed environments of space and determining the effects of atmospheric ethylene and 1-MCP on growth and development, and studying the uptake of compounds from contaminated soils through phytoremediation. USU continues to identify and characterize uniquely small genetic lines of crop plants. This past year we identified Redskin and Mohawk pepper as excellent substitutes for Triton pepper, which has poor seed quality. University of Wisconsin-Biotron has started replacing the old control cards (1970s made in-house) for the environmental control rooms with new Johnson Controls architecture and will be completed over 3 years. The Biotron is at 100% occupancy, so rooms will be converted to the new control system when projects end to not disrupt ongoing research experiments. The Biotron has conducted a growth trial of Brachypodium distachyo as a model system for biofuels research.
