Postdoctoral Research Fellowship in Microbial Biology for FY2001

这一行动为2001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，它还为最近的博士获得者提供了获得微生物生物学方面的额外培训的机会，在知名科学家的赞助下获得研究经验，并在本科生和研究生培训期间拓宽其科学视野，超越研究经验。这些奖学金还旨在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。这项研究和培训计划的标题是“蚜虫及其细菌内共生体在基因组水平上的共同进化”。蚜虫Melaphim rois和其细菌内共生菌Buchnera aphidicola之间的古老联系已经产生了一种专性的互惠关系，在这种互惠关系中，共生体为它们的宿主提供必要的氨基酸。在宿主复合体生命周期过程中，Buchnera基因的表达模式正在利用微阵列技术进行表征。

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 "Coevolution at the genomic level of aphids and their bacterial endosymbionts." An ancient association between the aphid, Melaphis rhois, and its bacterial endosymbiont, Buchnera aphidicola, has produced an obligate mutualism in which symbionts provide essential amino acids to their hosts. Buchnera gene expression patterns over the course of the host complex life cycle are being characterized using microarray technology.
