Expanded Plant Growth Facility for the University of GeorgiaDivision of Biological Sciences

请拨资金用于购买和建造两个温室和一个室内环境控制生长设施，其中包括三个生长室和12个生长室。温室的设计很容易修改，以符合未来可能出台的转基因植物繁殖法规。其中一栋房子内的三个房间将配备冷藏制冷，以在夏季几个月内提供降温。生长室和生长室将位于大学新的生物科学综合体内。它们将为常规植物生长提供相对大量的环境控制空间。实验室将提供更大和更精确的温度(100至400摄氏度)和光线(生长高度的0至1200微摩尔/光子m-2 S-1)范围，以满足更严格的生长要求。利用拟议新设施的主要项目包括：天然植物种群杂交(Arnold)；后期胚胎发生中活跃基因的调控(Galau)；植物种群的育种结构和基因流动(Hamrick)；花发育的遗传和环境控制(Malmberg)；两个多基因家族的差异表达(Meagher)；环境对热激和生长素调节的影响(Nagao)；转基因植物中的光敏色素结构和功能关系(PRATT)；C3植物中的光合作用驯化(SAGE)；玉米和水稻中的转座因子(Wessler)；以及黄花菜中苔藓的系统发育和亲缘关系(Wyatt)。

Funds are requested for the purchase and construction of two greenhouses with an attached headhouse and an indoor environmentally controlled growth facility consisting of three growth rooms and 12 growth chambers. The greenhouses are designed to be easily modified to conform to potential future regulations for the propagation of transgenic plants. Three rooms within one of the houses will be equipped with refrigerated cooling to provide temperature reduction during summer months. The growth rooms and growth chambers will be located within the University's new BioScience Complex. They will provide relatively large amounts of environmentally controlled space for routine plant growth. The chambers will provide greater and more precise ranges of temperature (100 to 400 C) and light (0 to 1200 micro mol/photons m-2 s-1 at growth height) for more rigorously defined growth requirements. Major projects utilizing the proposed new facilities include: hybridization in natural plant populations (Arnold); regulation of gene active in later embryogensis (Galau); breedng structure and gene flow in plant populations (Hamrick); genetic and environmental control of flower development (Malmberg); differential expression of two multigene families (Meagher); environmental effects on heat shock and auxin regulation (Nagao); phytochrome structure and functional relationships in transgenic plants (Pratt); photosynthetic acclimation in C3 plants (Sage); transposable elements in maize and rice (Wessler); and moss phylogeny and paternity in milkweeds (Wyatt).
