Microbial Community and Plant Growth-Promoting Bacteria in Rhizosphere of Halophyte Sesuvium portulacastrum L.

Abstract

植物促生菌(Plantgrowth-promotingbacteria,PGPB)是指能够通过直接或间接方式促进植物生长的细菌,在自然环境中PGPB有多种存在形式,既可以独立生存也可以与植物组织形成特定关系,常见的有根际促生菌和根系内共生菌,当前对植物根系促生菌的研究多集中于陆生植物和农作物中,而对植物修复中根系促生菌的研究相对较少。 本研究是在已开展的利用生态浮床技术进行富营养化海水植物修复的基础上,进一步研究修复植物海马齿(SesuviumportulacastrumL.)根系微生物群落结构及根系促生菌对植物生长的影响。首先,通过Illumina高通量测序平台分析海马齿根系、根际区和非根...The plant growth-promoting bacteria (PGPB)are bacteria tha can promote plant growth directly or indirectly. PGPB can be free-living, or form specific relationships with plants as rhizobacteria and endophytic bacteria combining with different plant tissues. Most studies focused on PGPB in terrestrial plants and crops, however, studies on PGPB in phytoremediation of eutrophicated seawater were rarel...学位:理学硕士院系专业:环境与生态学院_生态学学号:3312014115166
