Postdoctoral Research Fellowship in Microbial Biology for FY 2003

这一行动为2003财政年度NSF微生物生物学博士后奖学金提供资金。 该研究金支持关于原生动物、微藻、真菌、古菌、细菌和病毒物种的基础生物学的培训和研究，这些物种通常不被视为模式生物。此外，它为最近的博士生获得微生物生物学的额外培训提供了机会，在既定科学家的赞助下获得研究经验，并拓宽他们的科学视野，超越本科和研究生培训期间的研究经验。 这些研究金还旨在帮助新科学家指导其跨传统学科的研究工作，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“细菌代谢的实验室内演变：专业化的成本和生物体之间遗传交换的贡献”。“维持专门的细菌代谢和水平基因转移的作用所涉及的进化动力学正在使用实验进化进行研究。 正在进行生理分析和试图确定进化菌株中的有益突变，以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.
