qRT-PCR analysis. (a). Expression level detection of key enzyme genes related to POD, SOD, and CAT genes under 4 ℃ for 0 h, 48 h. (b). Expression level detection of NCED3 and ABI5 genes related to ABA path under 4 ℃ for 0 h, 48 h. (c). Expression level detection of MAPK17/18, GsSRK, MYC2, PR5, PYL4, PYR/PYL, WRKY key genes in RNA-seq. The bar represents the value of standard error (p < 0.01). Lowercase letters represent significance level. Means and SE values were calculated from at least three independent experiments
