Fig. 3From: De novo transcriptome in roots of switchgrass (Panicum virgatum L.) reveals gene expression dynamic and act network under alkaline salt stressCorrelation analysis between modules and physiological traits by WGCNA (b), and eigengenes expression patterns of 20 modules of WGCNA clustering (b). Each row corresponds to a clustering module, each column corresponds to a physiological trait, the colour of each grid at the row-column intersection indicates the correlation between the module and physiological data, red represents a positive correlation, blue represents a negative correlation, and the number in each grid represents the correlation coefficient and the P value. Twenty modules were marked with numeric value. 1: antiquewhite4; 2: bisque4; 3: blue; 4: brown; 5: coral2; 6: cyan; 7: darkmagenta; 8: darkorange; 9: darkseagreen4; 10: darkslateblue; 11: honeydew; 12: lightcyan; 13: lightsteelblue; 14: lightsteelblue1; 15: mediummorchid; 16: mediumpurple3; 17: midnightblue; 18: skyblue2; 19: white; 20: yellowgreen. In each module, red represents up-regulation and green represents down-regulation. The following corresponds to the degree of up-and-down adjustment of 18 samples in 6 groups (S0, S6, S24, T0, T6, T24)Back to article page
