Postdoctoral Research Fellowship in Microbial Biology for FY 2004

这一行动为NSF 2004财年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“调查叶球体中的细胞间和跨王国的通信”。群体感应，或由分泌的N-酰基高丝氨酸内酯(AHLS)介导的细胞间信号，发生在植物气生叶表面的细菌附生植物之间，在被称为叶圈的生境中。本研究探讨了分泌的AHL在细胞间细菌通讯中的调节和配置，并研究了AHL介导的与寄主植物的跨界通讯。微生物学和植物生物学研究技术的融合是主要的培训目标。

This action funds an NSF Postdoctoral Fellowship in Microbial biology for FY2004. 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 "Investigating Intercellular and Inter-kingdom Communication in the Phyllosphere." Quorum-sensing, or cell-to-cell signaling mediated by secreted N-acyl homoserine lactones (AHLs), occurs between bacterial epiphytes of plant aerial leaf surfaces, in the habitat called the phyllosphere. This research examines the regulation and disposition of secreted AHLs in intercellular bacterial communication, and investigates AHL-mediated inter-kingdom communication with host plants. The merging of microbiology and plant biology research techniques are a primary training goal.
