Specific regions on mtDNA were shown to associate with stool (panel A) and posterior fornix (panel B) taxonomy profile. -log10(pvalue) is used to represent the strength of association between specific mtSNP and clade. The –log10(pvalue) for each mtSNP on each clade were displayed in one Manhattan plot. The X-axis is labeled with mitochondrial gene names corresponding to their relative position on the chromosome. Significant association between mtSNPs and clade were marked in the plot.
