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.
水生植物叶片上的微生物群落尚未像根上的微生物群落那样被详细研究。本文使用 16S rRNA 扩增子测序研究了三种浮萍叶片上的微生物群落，并将其与根上的微生物群落进行了比较。三种浮萍的叶片微生物组成与根上的微生物组成明显不同。各种分类细菌，包括很少培养的酸杆菌门、装甲单胞菌门和疣微菌门，也从叶片中分离出来，但丰度略低于从根中分离出来的细菌。这些结果表明，浮萍叶片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用常规策略进行培养。
