The analysis of transcriptome sequencing in WT and OE plants under 4 ℃ for 48 h. (a) The heatmap of total differential expression genes. Rectangles in red and blue represent up and down-regulated expression. (b) The number of DEGs was shown by the volcano plot. Dots in red, green and red represent up, down and normal regulated genes, respectively. The number of the dots indicates the number of DEG. (c) The number of DEGs in main GO enrichments. (d) The expression level of key differential expression genes in MAPK path. Rectangles in red and blue represent up and down-regulated expression. (e) Expression level of differential expression genes in plant hormone signaling path. Rectangles in red and blue represent up and down-regulated expression. (f) Key differential expression genes expression in transcription factors activity. Rectangles in red and blue represent up and down-regulated expression. (g) Key differential expression genes expression in signaling receptor activity. Rectangles in red and blue represent up and down-regulated expression. (h) VaPYL9 overexpression participated in MAPK and plant hormone signaling KEGG path, and improved the activity of transcription factors and signaling receptors
