Fig. 1From: Characterization of bHLH/HLH genes that are involved in brassinosteroid (BR) signaling in fiber development of cotton (Gossypium hirsutum)Phylogenetic relationship of cotton bHLH/HLH transcription factors. MEGA 6.0 software was employed to construct an unrooted phylogenetic tree based on alignments of 437 bHLH/HLH domains identified from upland cotton (G. hirsutum) using the NeighborJoining (NJ) method with the following parameters: The number of differences model, pairwise deletion and 1000 bootstraps. Subfamilies are collapsed and represented as grey dots with area proportional to member numbers of each subfamilyBack to article page
