(A): Genes that matched the major (all) metabolic categories (E-value < 10−3) based on SEED subsystem. (B): Genes that matched stress response (E-value < 10−3) based on SEED subsystem. (C): KEGG analysis of the metabolic difference between eukaryotes and prokaryotes. “*” indicated a statistical significance with a P-value < 0.001 based on the mapped-read numbers in t-test. Yellow: prokaryotic symbionts, Green: eukaryotic symbionts.
