Figure 3.

K-means clustering of expression profiles of genes differentially expressed under different stress conditions. The clustering was performed on log₂ fold change for each gene under different stress conditions when compared with under control condition. The genes exhibiting a similar pattern of expression under different stress conditions [salt450, salt700, submergence (sub) and salt + submergence (salt + sub)] have been grouped together in four distinct groups. The scale at the bottom shows log₂ fold change. A colour version is available online.
