Postdoctoral Research Fellowship in Microbial Biology for FY 2003

该行动资助了2003财年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们的科学视野。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“将细菌细胞的群落组成和基因表达与盐度变化的沼泽沉积物中的碳和养分循环速率联系起来”。本研究探讨了沼泽沉积物中细菌动态作为盐度波动的函数。rRNA分析被用于分析群落组成和优势分类群的鉴定。同时，mRNA分析用于确定关键功能基因的表达。这项工作将把单个微生物种群与沉积物二氧化碳生产和养分保留之间的相互作用联系起来。

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 "Linking community composition and gene expression of bacterial cells to rates of carbon and nutrient cycling in marsh sediments with changing salinity." This research explores bacterial dynamics in marsh sediments as a function of fluctuating salinity. rRNA analysis is being used to analyze community composition and identification of dominant taxa. Concurrently, mRNA analysis is used to determine the expression of key functional genes. This work will link interactions between individual microbial populations to sediment carbon dioxide production and nutrient retention.
