DEGs in diploid and the autotetraploid sour jujube with or without the drought treatment. a Upset plot of DEGs in response to drought stress in the diploid and autotetraploid. DCK, D6h, D12h, and D48h represent diploid samples after 0 (untreated), 6, 12 and 48 h of drought treatment and the corresponding samples in the autotetraploid are labeled as TCK, T6h, T12h and T48h. The top column represents the DEGs number of intersections, and the left column graph represents the DEGs number of each dataset. Six separate orange dots represent the DEGs that only present in the one dataset. The DEGs present in at least two datasets is marked as connected orange dots. The connection represents the intersection, and the orange dots on the line represent the corresponding datasets. b Statistics of DEGs in diploids and autotetraploids under control conditions and after 6, 12 and 48 h of drought stress. c Correlation of expression changes observed by RNA-seq (Y-axis) and qPCR (X-axis)
