Detailed part of flavonoid metabolic subnetwork showing the subset of nodes or metabolites that constitute the process. The enzyme name, unigene names and expression patterns of each step are placed next to it. The square represents the difference multiple of ZZ_1 and HX_1 expression (log2 (HX_1 / ZZ_1)), the circle represents the FPKM value of ZZ_1, and the depth of color indicates the level of expression and difference.
