Phylogenetic tree, gene structure, and motif composition of the G. hirsutum BLH genes. a The phylogenetic tree was constructed using MEGA 6.0 with the neighbor-joining (NJ) method and 1 000 bootstrap replicates. b Exon and intron structure of BLH genes from G. hirsutum. The introns and exons are represented by black lines and red boxes, respectively. c Protein motifs. Each motif is represented using colored boxes
