Postdoctoral Research Fellowship in Microbial Biology for FY2001

这一行动为2001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，它为最近的博士生提供了机会，以获得微生物生物学方面的额外培训，在既定科学家的赞助下获得研究经验，并拓宽他/她的科学视野，超越本科和研究生培训期间的研究经验。这些奖学金还旨在帮助新科学家指导他们的研究工作，跨越传统学科，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“复杂宿主组合中微生物共同进化和内共生的分子研究”。“感染鸟类的咀嚼虱在专门的细胞中携带内共生细菌（pupilirickettsia）。虱子可能需要这些细菌来消化它们赖以生存的羽毛。正在对选定的核酸进行测序，以正确地将这些细菌置于一个同源系统中。 进化的速度正在被比较，与宿主的同源性正在被测试。 最后，正在评估内共生对核苷酸序列进化的影响。

This action funds an NSF Postdoctoral Fellowship in Microbial Biology for FY2001. 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 a recent doctoral recipients to obtain additional training in microbial biology, to gain research experience under the sponsorship of established scientists, and to broaden his/her 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 "Molecular studies of microbial coevolution and endosymbiosis in a complex assemblage of hosts." Chewing lice that infect birds harbor endosymbiotic bacteria (putatively Rickettsia) in specialized cells. Lice probably require these bacteria for digestion of the feathers on which they live. Selected nucleic acids are being sequenced to correctly place these bacteria in a phylogeny. Rates of evolution are being compared and cophylogeny with their hosts is being tested. Finally, the effect of endosymbiosis on nucleotide sequence evolution is being evaluated.
