Phylogenetic relationships, gene structures and protein domain architecture of GhZFP genes. a Phylogenetic relationships between GhZFPs. A phylogenetic tree was generated using the maximum likelihood method with 1,000 bootstrap iterations in MEGA 6.0 software. b Gene structure (exon-intron organization) analysis of GhZFPs. Exons and introns are represented by purple boxes and black lines, respectively. The scale bar is shown at the bottom. c The protein domain architecture of GhZFP genes. The number and order of motifs in each GhZFP genes are shown. Motif 2 in (c) is the ZFP domain
