Figure 4. Contribution of each genus to the abundance of pathways related to branched-chain amino acid biosynthesis (A-G).

Those genera not representing the 10 most abundant were categorized together as “Others.” I, initial raw vegetable group (n = 8); P, pretreatment group (n = 8); S, salt stock preparation group (n = 8). *, a pathway of branched-chain amino acid biosynthesis; † , pathways of isoleucine biosynthesis; ‡ , a pathway of valine biosynthesis. Contributions to pathway abundances were calculated by multiplying the relative abundance by the copy number of the gene(s).
