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“细菌可以通过粘液挤出移动吗？黄色粘球菌中A型运动的物理学”。黄色粘球菌利用两种不同的遗传机制：社会性(S)和冒险(A)运动性，通过滑行移动。这是一项基于蓝藻中发现的喷嘴状细胞器的黏液挤出模型对A型运动性的研究。目前正在探索一种理论模型，并进行实验，以确定这种类型的机制是否可以驱动A型运动。

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 "Can Bacteria Move by Slime Extrusion? The physics of A-type motility in Mxyococcus xanthus." Myxococcus xanthus moves by gliding utilizing two distinct genetic mechanisms: Social(S) and Adventurous(A) motility. This is a study of A-type motility using a slime extrusion model based on a nozzle-like organelle discovered in cyanobacteria. A theoretical model is being explored and experiments performed to determine if this type of mechanism can drive A-motility.
