Epiphytic bacteria and bacterioplankton affect the plant physiology and nutrient transformation of submerged macrophytes. The community structure of epiphytic bacteria and bacterioplankton is fundamental to understanding their ecological role and, in turn, the effect of macrophytes on bacteria. In this study we compared the composition of epiphytic bacteria in association with Potamogeton pectinatus, as well as that of the surrounding bacterioplankton at different growing stages of P. pectinatus. Proteobacteria, Bacteroidetes, Cyanobacteria, and Actinobacteria were dominant groups in both epiphytic bacteria and bacterioplankton, yet there was a significant discrepancy in the community structure among different growing stages, and bacterioplankton exhibited higher diversity than epiphytic bacteria during the entire growing period. The relative abundance of most bacteria showed opposite trends between epiphytic bacteria and bacterioplankton. Further studies should focus on the underlying interactions between epiphytic bacteria and their host plants.

洪泽湖竹Pot附生细菌及其浮游植物的群落结构。
附生细菌和浮游细菌影响沉水大型植物的植物生理和养分转化。附生细菌和浮游细菌的群落结构对于理解其生态作用以及大型植物对细菌的影响至关重要。在这项研究中,我们比较了与毛藻(Potamogeton pectinatus)有关的附生细菌的组成,以及毛藻(P. pectinatus)不同生长阶段周围细菌的组成。变形杆菌,拟杆菌,蓝细菌和放线菌附生细菌和浮游细菌均是优势种群,但在不同生长期的群落结构存在显着差异,并且在整个生长期,浮游细菌的多样性高于附生细菌。大多数细菌的相对丰度在附生细菌和浮游细菌之间显示出相反的趋势。进一步的研究应集中在附生细菌与其宿主植物之间的潜在相互作用。
