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跨越传统的学科界限指导他们的研究工作，并利用包括外国地点在内的独特的研究资源、地点和设施。这项研究和培训计划的标题是“数千个核的真菌细胞中核分裂的协调”。本研究研究了多核丝状真菌Ashbya Cotsypii的核分裂规律。在这种生物体中，相邻的细胞核表现出独立的细胞周期，导致共同细胞质内的异步有丝分裂。利用细胞生物学和分子遗传学方法，这项研究评估了独特细胞周期的关键分子控制。

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 "Coordination of nuclear division in a fungal cell with thousands of nuclei." This research studies the regulation of nuclear division in the multinucleated, filamentous fungus Ashbya gossypii. In this organism, neighboring nuclei display independent cell cycles resulting in asynchronous mitoses within a common cytoplasm. Using cell biological and molecular genetic approaches, the research evaluates the key molecular controls of the unique cell cycle.
