Bacteria community provides essential ecological services to rice plants. The bacterial diversity of rice varies across host plant genotype and organs. This study employed 16S rDNA amplicon sequencing to characterise the bacterial community associated with three rice landraces using leaf blade and stem samples. The prokaryotic community found in these rice landraces comprised of two kingdoms, 12 phyla, 25 classes, 40 orders, 80 families, and 118 genera. Proteobacteria (53.9%) was the most abundant phylum. The most abundant genus was an undefined genus under Cyanobacteria (33.0%). Homogeneity of prokaryotic community was observed across the three rice landraces, which may suggest a high similarity in biological and genetical properties of the rice landraces. The difference in prokaryotic composition between leaf blade and stem was depicted based on principal coordinate analysis. This study observed that the prokaryotic inhabitants in rice plants is predominantly determined by rice plant organs.
细菌群落为水稻植株提供了重要的生态服务。水稻的细菌多样性因宿主植物基因型和器官而异。本研究采用 16S rDNA 扩增子测序技术，对三种水稻地方品种的叶片和茎样本中的细菌群落进行了特征描述。在这些水稻地方品种中发现的原核生物群落由两个界、12 个门、25 个纲、40 个目、80 个科和 118 个属组成。变形菌门（53.9%）是最丰富的门。最丰富的属是蓝细菌下未定义的属（33.0%）。这三种水稻地方品种的原核生物群落具有同质性，这可能表明这些水稻地方品种在生物学和遗传学特性上具有高度相似性。基于主坐标分析描绘了叶片和茎之间原核生物组成的差异。本研究观察到，水稻植物中的原核生物居民主要由水稻植物器官决定。
