Figure 6. Functional classification of the accessory genes of (A) S. alvi SAGs and (B) G. apicola SAGs based on COG categories.

303 of 755 accessory genes of S. alvi SAGs and 476 of 851 accessory genes of G. apicola SAGs could be classified into COGs. Categories covering ≥5% of the classified accessory genes are shown. Minor categories (<5%) are summarized in the grey colored area of the pie charts. Categories R, S, and L include genes associated with mobile genetic elements.
