粘细菌的种群生态及其生存策略

Population ecology and survival strategy of myxobacteria

摘要:

粘细菌是一类革兰氏阴性细菌, 属于delta变形菌纲, 具有复杂的多细胞群体行为特性, 并能够产生丰富的次级代谢产物, 是重要的药源微生物和原核生物细胞间通讯、多细胞形态发生、生物进化等研究中的模式生物。在简要介绍粘细菌基本特性的基础上对粘细菌的生态多样性、生存策略及其在生态系统中功能进行了综述。

Abstract:

The Gram-negative myxobacteria are phylogenetically located in the delta division of Proteobacteria. Myxobacteria are famous for their complicated multicellular behavior and excellent production ability of secondary metabolites, and are thus among important microbial resources for drug screening and of model organisms for the studies of prokaryotic intercellular communication, multicellular morphogenesis, and biological evolution. In this paper, we reviewed characteristics of myxobacteria and progresses related to their population diversity, ecological distribution, potential survival strategies and ecological functions.

Key words:myxobacteria, social behavior, diversity, natural habitats, survival strategy, ecological functions
