Abstract

Abstract: To obtain the compositional and functional information of the rhizosphere microbiota of Lemna minor in the Dongda River Wetland and the Laoyu River Wetland of the Dianchi Lake of Kunming, so as to achieve sustainable development and utilization as well as biodiversity protection of wetland resources and provide biological disaster prediction, fluorescence in situ hybridization was used to investigate the rhizosphere microbiota of Lemna minor in these two wetlands during spring and autumn. By comparing the differences in composition and abundance of the rhizosphere microbiota of Lemna minor in these two sites, we found that except for the abundance of Chloroflexus, that of ammonia oxidizing bacteria, denitrifying bacteria, sulfate-reducing bacteria and methanogenic bacteria as well as Proteobacteria and Bacteroides varied at different degrees with changes in wetlands and seasons. The results from this study can be used not only as biological indicators of the water quality, but as an effective technology support to manage the water quality of the wetlands.

Key words: wetland resource utilization, duckweed root microorganisms, functional flora, fluorescence in situ hybridization
