Differential expression profiling of genes involved in phytohormone biosynthesis in the rapeseed plants between the control (Ctrl) and salt conditions. a-e Biosynthesis pathways and differential expression profiling of the genes involved in auxin (IAA, a), cytokinin (CTK, b), gibberellin (GA, c), abscisic acid (ABA, d), and jasmonic acid (JA, E). AAO, abscisic aldehyde oxidase; ADH, alcohol dehydrogenase; AOC, allene oxide cyclase; AOS, allene oxide synthase; CPS, ent-copalyl diphosphate SYNTHETASE; DAO, Dioxygenase for Auxin Oxidation; EKO, ent-kaurene 19-oxidase; GAox, GA oxidase; GH3s, Gretchen Hagen 3 s; KS, ent-kaurene synthase; LOX, lipoxygenase; NCED, 9-cis-epoxycarotenoid dioxygenase; OPR, 12-oxo-phytodienoic acid reductase; PLA1, phospholipase A1; ZEP, zeaxanthin epoxidase; ZSY, neoxanthin synthase. For the transcriptome sequencing, uniform rapeseed plants after 7-day seed germination were cultivated under NaCl-free (control) for 10 days, and then they were transferred to the solution containing 200 mM NaCl for 12 h. The heatmaps show gene expression levels as indicated by the FPKM values. The differentially expressed genes presenting higher expression levels between the control and 200 mM NaCl conditions are denoted by asterisks
