Fig. 2

A circular cladogram of ZIK subfamily in seven examined species. OrthoMCL predicted orthogroup clusters are depicted by colored stripes beside sequence identifiers. Significantly differentially regulated genes for Gossypium hirsutum are depicted with circles on the outer perimeter where blue circles indicate significant downregulation, red circles significant upregulation, and grey circles are not differentially regulated. Circles represent 1) cold stress, 2) heat stress, 3) drought stress, and 4) salt stress from innermost - > outermost circle
