Figure 4

Heatmap and hierarchical cluster analysis of differentially expressed genes based on the expression pattern of 661 DEGs derived from the control (0 M NaCl) and salt-treated (0.5 M NaCl) P. indica 14 days after treatment. The color scale represents the expression of DEGs in terms of normalized expression of DEGs between control and salt-treated samples. Tool: gplots package in R (3.1.1).
