RAF subfamily within seven plants. 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. Clade B3 is a combination of previously defined clades B1 and B3. Clade C3 is a combination of previously defined clades C3 and C4. Clades B2, B4, C1, C2, C5, C6, and C7 are analogous to previously established clades. Leaves are colored according to the previously proposed cladding
