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“纤毛虫基因组加工的进化，具有二形核的真核微生物。”纤毛虫是真核微生物，具有两种核，一种是胚系微核，一种是体细胞大核。大核的发育涉及基因组的加工，包括染色体碎裂、序列切除和扩增。这项研究考察了纤毛虫的不同谱系，它们的加工程度不同，以阐明基因组加工的进化。

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 "Evolution of genome processing in Ciliates, eukaryotic microorganisms with dimorphic nuclei." Ciliates are eukaryotic microorganisms that possess two types of nuclei, a germline micronucleus and a somatic macronucleus. Development of the macronucleus involves processing of the genome, including chromosome fragmentation, sequence excision, and amplification. This study examines diverse lineages of ciliates, which vary in extent of processing, in order to elucidate the evolution of genome processing.
