Postdoctoral Research Fellowship in Microbial Biology for FY2001

这一行动为2001财政年度NSF微生物生物学博士后奖学金提供资金。 该研究金支持关于原生动物、微藻、真菌、古菌、细菌和病毒物种的基础生物学的培训和研究，这些物种通常不被视为模式生物。此外，它为最近的博士生提供了机会，以获得微生物生物学方面的额外培训，在既定科学家的赞助下获得研究经验，并拓宽他/她的科学视野，超越本科和研究生培训期间的研究经验。这些奖学金还旨在帮助新科学家指导他们的研究工作，跨越传统学科，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“细菌能通过粘液挤压移动吗？ 黄色粘球菌A型运动的物理学粘球菌通过两种不同的遗传机制滑动移动：社会（S）和冒险（A）运动。 这是一个A型运动的研究，使用基于蓝藻中发现的一个类似于矛状细胞器的粘液挤出模型。 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.
