A comprehensive selection of key genes potentially related to the multiple stress-tolerant phenotypes. A DEGs under five stress conditions; B Venn diagram of DEGs under the five stress conditions, including 28 shared DEGs; C GO enrichment analyses of 28 shared DEGs; D the pathway of cyanoamino acid metabolism; E protein–protein interaction network of 28 shared DEGs. In the plot, the bluer the circle, the greater the contribution of the gene, the thicker the line, the stronger the interaction between the two genes; F Relative expression level of the DEGs of unknown function in 28 shared DEGs; G DEGs regulated by the two identified TFs in 28 shared DEGs
