Transcriptome analysis of P. grandiflorus was performed by high-throughput sequencing. (a) Venn diagram showing the number of DEGs among different treatments and the only upregulated and downregulated DEGs; (b) Hierarchical analysis of the overlapping 66 DEGs at different concentrations of salt stress. (In the graph, the horizontal coordinates represent different experimental groups, the vertical coordinates represent the corresponding differentially expressed genes in this group, the color blocks in different positions represent the relative expression amount of genes in the corresponding positions, and the red color represents the high expression of this gene, blue indicates low expression of this gene.) (c) GO pathway enrichment analysis based on the 66 overlapping DEGs; and (d) KEGG pathway analysis based on the 66 overlapping DEGs
