Postdoctoral Research Fellowship in Microbial Biology for FY 2003

该行动资助了2003财年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们的科学视野。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“细菌代谢的实验室进化：专业化的代价和生物间基因交换的贡献”。进化动力学涉及维持特殊的细菌代谢和水平基因转移的作用正在使用实验进化进行检查。正在进行生理学分析，并试图确定进化菌株中有益的突变，以便深入了解它们增加的适应性。

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.
