The microbial communities inhabiting the fronds of duckweeds have not been investigated in as much detail as those on the roots. We herein examined the microbial communities in three duckweed species using 16S rRNA amplicon sequencing and compared them to those on the roots. The microbial compositions of the fronds were distinct from those of the roots in the three species. Various types of taxonomic bacteria, including rarely cultivated phyla, Acidobacteria, Armatimonadetes, and Verrucomicrobia, were also isolated from the fronds, but at a slightly lower abundance than those from the roots. These results suggest that duckweed fronds are an alternative source for isolating rare and novel microbes, which may otherwise be recalcitrant to cultivation using conventional strategies.

：微生物群落的叶状体和三浮萍种根的比较分析紫萍，浮萍和细脉浮萍

浮萍叶片上的微生物群落没有像根上的微生物群落那样详细地研究。我们在此使用 16S rRNA 扩增子测序检查了三种浮萍物种中的微生物群落，并将它们与根部的微生物群落进行比较。叶状体的微生物组成与三个物种根部的微生物组成不同。各种类型的分类细菌，包括很少栽培的门、酸杆菌、Armatimonadetes 和疣微菌，也从叶中分离出来，但丰度略低于根中的丰度。这些结果表明浮萍叶是分离稀有和新型微生物的替代来源，否则这些微生物可能难以使用常规策略进行培养。
