Global coexpression analysis: Coexpression sub-modules with jaw or species specific expression patterns. a The colours represent the coexpression modules identified using data from bots jaws. Correlation (r) score and p-value significance of module to jaw type or species. Red denoted strong postive correlation and blue denotes strong negative correlation. Sub-modules of coexpressed genes within b Blue module c Plum2 and d Cyan modules. The red and blue connecting lines between the genes in each sub-modules indicate significant positive and negative expression correlations, respectively (P < 0.05). The predicted TF(s) at upstream of each each sub-module are depicted in square shape gene symbol with their related functions. The red, blue and white shadings for genes respectively indicate increased expression in oral and pharyngeal jaws, and no expression difference between the jaws
