Postdoctoral Research Fellowship in Microbial Biology for FY 2003

这一行动为2003财年NSF微生物生物学博士后奖学金提供了资金。该奖学金支持关于原生动物、微藻、真菌、古生物、细菌和病毒物种的基本生物学的培训和研究，这些物种通常不被认为是模式生物。此外，它还为新近获得博士学位的人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们的科学视野，超越研究经验。这些奖学金的进一步设计是为了帮助新科学家引导他们的研究工作跨越传统的学科界限，并利用独特的研究资源、地点和设施，包括外国地点。研究和培训计划的标题是“细菌新陈代谢的实验室内进化：专业化的成本和有机体之间基因交换的贡献”。参与维持特定细菌新陈代谢和水平基因转移作用的进化动力学正在利用实验进化进行检验。正在进行生理分析，并试图识别进化菌株中的有益突变，以深入了解它们更适合的情况。

This action funds an NSF Postdoctoral Fellowship in Microbial Biology for FY2003. 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 recent doctoral recipients to obtain additional training in microbial biology, to gain research experience under the sponsorship of established scientists, and to broaden their 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 "In-lab evolution of bacterial metabolism: costs of specialization and the contribution of genetic exchange between organisms." The evolutionary dynamics involved in the maintenance of specialized bacterial metabolism and the role of horizontal gene transfer is being examined using experimental evolution. Physiological analyses and attempts to identify the beneficial mutations in the evolved strains are being performed in order to gain insight into their increased fitness.
