All differentially expressed genes in the transcriptome sequencing data. a Venn diagram of all the differentially expressed genes in each comparison. The col. and con indicate cold and control conditions. b Number of differentially expressed genes that were up- or down-regulated in each comparison. Up means upregulated under the sterile condition in comparison to the different conditions or in BS366 in comparisons between different samples under the same conditions. c Hierarchical cluster analysis of all differentially expressed genes. The color key represents the normalized log₂ transformed expression of genes, with genes with expression shown in red and those with low expression shown in blue
