(A, B) PPI network and corresponding processes related to fatty acid biosynthesis and leucine catabolism. The component proteins of fatty acid biosynthesis and leucine catabolism in Arabidopsis thaliana are from a published paper [38]. A: The sub-networks related to fatty acid biosynthesis are constructed based on our medium confident bins. Each of the five circles in different colors encloses the corresponding one of the five interactive modules in the fatty acid biosynthesis depicted in Fig 3 (C). B: The sub-networks related to leucine catabolism. The colored circles represent the function modules corresponding to the function unit in Fig 3 (D). C: The fatty acid biosynthesis with the candidate genes in Arabidopsis thaliana, proteins in each square with one of the five different colors in the figure are the same as the proteins in the related sub-network in Fig 3(A). D: The leucine degradation pathway in mitochondrion, the proteins in different colored squares are the same proteins depicted in the corresponding sub-networks in Fig 3(B).
