Stress response analysis of LBDs in Jatropha curcas. (A) Expression of JcLBDs in drought treatment. C and D represent control and drought treatments, respectively, and 1d, 4d and 7d correspond to one, four, and seven days post-treatment sampling, respectively, and L and R represent leaf and root tissues, respectively. (B) Expression of JcLBDs under salt stress. C and S represent control and salt stress treatments, respectively, 2h, 2d and 7d correspond to 2 h, two days and seven days post-treatment sampling, respectively, and L and R represent leaf and root tissues, respectively. Heatmap was drawn by pheatmap using log10(TPM) values.
