Differential expression profiling of the genes involved in photosynthesis and anthocyanin biosynthesis in the shoots between the control (Ctrl) and salt conditions. a Differential expression profiling of the genes involved in photosynthesis. b The anthocyanin biosynthesis pathway in plants and differential expression profiling of the genes involved in anthocyanin biosynthesis. ANS, anthocyanidin synthase; C4H, cinnamic acid 4-hydroxylase; CHI, chalcone-flavanone isomerase; CHS, chalcone synthase; 4CL, coumaroyl-CoA synthase; DRF, dihydroflavonol 4-reductase; F3H, flavanone 3-hydroxylase; F3’H, flavanone 3′-hydroxylase; GT, glycosyltransferase; PAL, phenylalanine ammonia lyase. c General expression profiling and number of the differentially expressed MYB transcription factor genes. d Differential expression profiling of the PAP1 (MYB75) and PAP2 (MYB90). PAP, production of anthocyanin pigment. e General expression profiling and number of the differentially expressed bHLH transcription factor genes. f Differential expression profiling of the bHLH122 family genes. g Differential expression profiling of the WD40 family genes. For the transcriptome sequencing, uniform rapeseed plants after 7-day seed germination were hydroponically grown under NaCl-free (control) for 10 days, and then they were transferred to the solution containing 200 mM NaCl for 12 h. Up, upregulation; down, down regulation. The heatmaps show gene expression levels as indicated by the FPKM values. The differentially expressed genes presenting higher expression levels between the control (Ctrl) and salt (200 mM NaCl) conditions are denoted by asterisks
