Co-expression analysis of starch and sucrose metabolism and galactose metabolism. (A) Schematic diagram of the mechanism. (B) The heat maps displaying expression of DEGs. The heatmap colored in blue and yellow indicates metabolite accumulation. The heatmap colored in blue and pink indicates gene expression. Suc represented sucrose. (C) Changes in the content of key metabolites. AMY, alpha-amylase; ISA, isoamylase; AGPase, ADP-glucose pyrophosphorylase; INV, invertase; SPS, stachyose synthase; SUS, sucrose synthase; SCRK,; HK,; TPS, trehalose 6-phosphate synthase; GN, encoding glucan endo-1,3-beta-glucosidase; TPP, trehalose 6-phosphate phosphatase; GALM, aldose 1-epimerase; BGAL, beta-galactosidase; GALE, UDP-glucose 4-epimerase; GolS, galactinol synthase; RFS, raffinose synthetase; α-Gal, alpha-galactosidase; EG, endoglucanase
