Comparative analysis of 16S rRNA of bacteria associated with the ancient annelid Platynereis dumerilii: structural conservation across clades

Year: 2026

Type: article

Abstract: The study dealt with the comparative analysis of the 16S rRNA of bacteria associated with Platynereis dumerii belonging to five major phyla namely Proteobacteria, Actinobacteria, Cyanobacteria,Femicutes, and Bacteroidetes, integrating their phylogenetic reconstruction and delineation. Maximum likelihood trees reveal consistent clustering of bacterial taxa into five major phyla.The phylogenetic coherence and conserved 16S rRNA motifs across clades suggest functional constraints and possible co-evolution with the host. These findings provide a molecular framework for understanding the evolutionary ecology of P. dumerilii-associated microbiota and highlight conserved ribosomal features as phylogenetic markers across bacterial lineages.
