Analysis of DEGs encoding TFs in diploid and autotetraploid sour jujube. a The numbers of TF genes differentially expressed in the diploid and autotetraploid at 6, 12 and 48 h after drought treatment. b The differential expression levels of NAC genes in the diploid and autotetraploid under drought-stress conditions. Gradient colour bar code at the top indicates log2 (Fold change) values with up-regulated genes represented by positive values and down-regulated genes represented by negative values. c–h Verification of differential expression levels of six NAC genes LOC10747970 (c), LOC107430472 (d), New gene 6259 (e), LOC107406551 (f), New gene 7719 (g) and LOC107407948 (h). The vertical bars show the standard error and a significance level of 0.05 was used for different letters above bars
