This action funds an NSF Postdoctoral Fellowship in Microbial Biology for FY2001. The fellowship supports training and research on the basic biology of protozoan, microalgal, fungal, archaeal, bacterial and viral species that are not generally considered to be model organisms. Further, it provides opportunities for a recent doctoral recipients to obtain additional training in microbial biology, to gain research experience under the sponsorship of established scientists, and to broaden his/her scientific horizons beyond the research experiences during the undergraduate and graduate training. These fellowships are further designed to assist new scientists to direct their research efforts across traditional disciplinary lines and to avail themselves of unique research resources, sites, and facilities, including foreign locations. The research and training plan is entitled "Utilizing biochemical and genetic methods to dissect how a cyanobacterium senses and responds to changing light conditions." The test organism is Fremyella diplosiphon. A detailed biochemical analysis is being made of RcaE, a putative phytochrome-like photoreceptor that controls the process of complementary chromatic adaptation (CCA). Specifically, the experiments address the phosphorelay model which holds that RcaE is the photoreceptor that differentially controls the phosphorylation state of the response regulator RcaF in different light qualities, which in turn regulates the phosphorylation levels of RcaC.

本行动资助2001年度美国国家科学基金会微生物生物学博士后奖学金。该奖学金支持一般不被认为是模式生物的原生动物、微藻、真菌、古细菌、细菌和病毒物种的基本生物学培训和研究。此外，它为最近的博士学位获得者提供了在微生物生物学方面获得额外培训的机会，在知名科学家的赞助下获得研究经验，并在本科和研究生培训期间拓宽他/她的科学视野。这些研究金的进一步目的是帮助新科学家指导他们的研究工作跨越传统的学科界线，并利用独特的研究资源、地点和设施，包括国外的地点。这项研究和培训计划的标题是“利用生物化学和遗传方法来解剖蓝藻如何感知和应对不断变化的光线条件。”试验生物是双虹吸自由菌。RcaE是一种被认为控制互补色适应（CCA）过程的光敏色素样光感受器，目前正在进行详细的生化分析。具体来说，实验解决了磷酸化中继模型，该模型认为RcaE是光感受器，在不同光质量下不同程度地控制反应调节因子RcaF的磷酸化状态，进而调节RcaC的磷酸化水平。
