We evaluated phylogenetic clustering of bacterial and archaeal communities from redox-dynamic subtropical forest soils that were defined by 16S rRNA and rRNA gene sequences. We observed significant clustering for the RNA-based communities but not the DNA-based communities, as well as increasing clustering over time of the highly active taxa detected by only rRNA.
我们评估了基于 16S rRNA 和 rRNA 基因序列定义的氧化还原动态亚热带森林土壤中细菌和古菌群落的系统发育聚类。我们观察到基于 RNA 的群落存在显著聚类,而基于 DNA 的群落则没有,并且仅通过 rRNA 检测到的高度活跃类群的聚类随时间增加。
