Relative abundance of higher taxonomic groups (sequences proportion over 1% of the total DNA or RNA abundance) based on the DNA-derived (A) and RNA-derived (B) approaches for each sample. Others refer to groups with relatively lower abundance (sequences proportion < 1% of the total DNA and RNA abundance). Asterisks indicate that the community composition was significantly different (Chi-square test, P < 0.05) between the DNA and RNA approaches for the same sample.
