RUI: Acquisition of a Controlled Environment Chamber

受控环境舱将用于植物学研究。A.J. Shaw的研究将探讨苔藓植物自然种群的性别比例决定机制。将从种群中分离出单孢子培养物，并评估雄性和雌性配子体在生态重要性状上的差异。J.M. Bernard将研究温度对湿地植物生活史特征的影响，包括无机营养和碳分配。生长室将允许Bernard博士和合作的本科生通过在受控条件下测试假设来扩展先前的实地研究。I.A. Tamas将利用转基因烟草研究吲哚乙酸（IAA）对植物形态发生的影响机制。Tamas博士的工作需要在无性系条件下进行组织培养，以及转基因整株烟草的生长。B.P.史密斯将研究环境因素之间的相互作用，如湿度和螨虫寄生，以确定蚊子种群的死亡率。史密斯博士的研究需要严格控制温度、光周期和湿度。

Controlled - environment chambers will be obtained for use in botanical studies. Research by A.J. Shaw will investigate mechanisms of sex ratio determination in natural populations of bryophytes. Single spore cultures will be isolated from a population and differences between male and female gametophytes in ecologically important traits will be assessed. J.M. Bernard will investigate the effects of temperature on life history characteristics, including inorganic nutrition and carbon allocation, in wetland plants, Growth chambers will allow Dr. Bernard and collaborating undergraduate students to expand previous field studies by testing hypotheses under controlled conditions. I.A. Tamas will investigate mechanisms underlying the effects of indoleacetic acid (IAA) on plant morphogenesis using transgenic tobacco plants. Dr. Tamas' work requires tissue culture under axenic conditions as well as the growth of transgenic whole tobacco plants. B.P. Smith will investigate interactions between environmental factors, such as humidity and parasitism by mites, in determining mortality in populations of mosquitoes. Dr. Smith's research requires close control of temperature, photoperiod, and humidity.
