From: Microbiota diversity and gene expression dynamics in human oral biofilms
Total (DNA-based) and active (RNA-based) microbiota composition in the human oral biofilm from individual NoCa-01. Microbial diversity is inferred from 16S rDNA and 16S cDNA taxonomic assignment, respectively, from reads obtained by direct pyrosequencing of the DNA and cDNA of a 24 h dental plaque sample. Relative abundance of bacterial genera from metagenomic data differs from that obtained from metatranscriptomic data. The former would correspond to the total bacterial composition in the sample whereas the latter would represent the “active microbiota” as inferred by their presence in samples’ RNA.
