Postdoctoral Research Fellowship in Microbial Biology for FY2001

本行动资助2001年度美国国家科学基金会微生物生物学博士后奖学金。该奖学金支持一般不被认为是模式生物的原生动物、微藻、真菌、古细菌、细菌和病毒物种的基本生物学培训和研究。此外，它为最近的博士学位获得者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/她的科学视野。这些研究金的进一步目的是帮助新科学家指导他们的研究工作跨越传统的学科界线，并利用独特的研究资源、地点和设施，包括国外的地点。这项研究和培训计划的标题是“蚜虫及其细菌内共生体基因组水平上的共同进化”。蚜虫Melaphis rhois和它的细菌内共生体Buchnera aphidicola之间的古老联系产生了一种专性互惠关系，共生体为它们的宿主提供必需的氨基酸。利用微阵列技术对宿主复杂生命周期过程中的布氏菌基因表达模式进行了表征。

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.
