The numbers of DEGs up- and down-regulated in each library. The DEGs (differentially expressed genes) were identified using a threshold of FDR (false discovery rate) ≤ 0.001 and absolute value of log2 Ratio ≥ 1. D1, D2 and D3 represented three drought-treated libraries, corresponding to 2, 8 and 24 h after drought treatment; C1, C2 and C3 represented three cold-treated libraries, corresponding to 2, 8 and 24 h after cold treatment. The numbers of the DEGs in each library were shown in terms of up-regulation and down-regulation, respectively.
