Differentially expressed genes in BR and ABA signaling in spinach under heat stress revealed from transcriptomic analysis. The columns represented fold change (Log2 transformed) of genes in leaves under heat treatment for 2, 4, 12, and 24 h compared with 0 h. The rows represented individual genes, and the genes with various Gene ID were marked with different numbers companied with Gene symbols. The color bar on the right of the heat map was based on the transcriptome data. Red and blue colors indicated up- and down- regulated genes, respectively. **, p < 0.01; ***, p < 0.001. The detailed information was included in Additional file 6.
