Differential expression profiling of genes involved in the transport of sodium (Na+), chlorion (Cl−), potassium (K+), and calcium (Ca2+) ions in rapeseed plants between the control (Ctrl) and salt conditions. a A molecular model showing the genes involved in the transport of Na+, K+, and Ca2+ in plants. b-d Differential expression profiling of the genes involved in the transport of K+ (b), Na+/Cl− (c), and Ca2+ (d) in the rapeseed plants between the control and 200 mM NaCl conditions. ALMT, aluminum-activated malate transporter; AKT/KAT, Arabidopsis K+ transporter; ANXD, annexin D; BASS, bile acid sodium symporter; CAX, cation exchanger; CCX, cation calcium exchanger; CNGC, cyclic nucleotide-gated channel; GLR, glutamate-like receptor; HKT, high-affinity K+ transporter type; KEA, K+ efflux antiporter; KCO, two-pore K+ channel; NHX/NHD, Na+/H+ antiporter; SKOR, stelar K+ outward rectifier; SOS, salt overly sensitive. For the transcriptome sequencing, uniform rapeseed plants after 7-d seed germination were hydroponically grown under NaCl-free (control) for 10 d, 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
