英文摘要	Epibiotic bacterial community colonized on the plant leaf plays important roles in promoting plant growth and nutrient absorption, but is sensitive to environmental changes. As one of the most important environmental factors affecting the growth of plants and photosynthetic microorganisms, light may affect the diversity, composition, and interactions of the epibiotic bacterial community. Submerged plants in the aquatic ecosystem may be more sensitive to light intensity variations compared to the terrestrial plants since they usually receive less light. However, the effects of light on the interactions between the submerged plants and their epibiotic mi-crobial communities remain uncertain. Here we used the 16S rRNA gene high-throughput sequencing to inves-tigate the diversity and composition of the bacterioplankton and epibiotic bacterial communities of the Cabomba caroliniana under four different shading levels. A total of 24 water and leaf samples were collected from the ex-perimental microcosms near Lake Taihu. We found the epibiotic bacterial community possessed a higher diver-sity than that of the bacterioplankton community, although the alpha diversity of the bacterioplankton community was more susceptible to different levels of shading. SourceTracker analysis revealed that with the in-crease of shading, the colonization of bacterioplankton to epibiotic bacteria decreased. Network analysis showed that the bacterial community network at 50% shading level had the lowest modularity and highest clustering co-efficient compared to the bacterial community networks of other shading levels. Our findings provided new un-derstandings of the effects of different light intensities on the epibiotic bacterial communities of submerged macrophytes. (c) 2021 Elsevier B.V. All rights reserved.
