Postdoctoral Research Fellowship in Microbial Biology for FY 2002

本行动资助2002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题目是“环境变化对野草群落中一种通用微生物病原体：大麦黄矮病毒的影响”。微生物生物学的一个主要挑战是了解环境变化如何影响微生物。病原微生物感染多种宿主物种受到宿主群落组成改变的影响。这项研究正在测试环境变化的其他三个组成部分——氮沉降、物种多样性减少和土地利用变化——如何与寄主群落组成相互作用，影响大麦黄矮病毒，一种禾草的通用病毒病原体。

This action funds an NSF Postdoctoral Fellowship in Microbial Biology for FY2002. 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 "Effects of environmental change on a generalist microbial pathogen: barley yellow dwarf virus in wild grass communities." A major challenge for microbial biology is understanding how environmental change affects microbes. Pathogenic microbes infecting multiple host species are influenced by altered host community composition. This research is testing how three other components of environmental change - nitrogen deposition, decreased species diversity, and land-use change - interact with host community composition to affect barley yellow dwarf virus, a generalist viral pathogen of grasses.
