Key phylotypes of the gut microbiota responding to age identified using LEfSe. The left histogram shows the LDA scores computed for features (OTU level) differentially abundant among different phases. The right heat map shows the mean relative abundance (log-transformed) of OTUs in each group. The values on the color bar represent the mean sequence number with log-transformed. Phylotype names marked with different colors indicate the corresponding phylum (blue: Proteobacteria, green: Firmicutes; orange: Bacteroidetes red: Verrucomicrobia; purple: Actinobacteria). Sample sizes are the same as Fig. 1.
