Phylogenetic relationships, gene structure, and protein domain architecture of GhEXP genes. a Phylogenetic relationships of 93 GhEXP proteins. The phylogenetic tree was constructed with MEGA 6.0 software using the neighbour-joining (NJ) method with 1000 bootstrap replicates. b Gene structure (exon-intron organization) analysis of GhEXPs. The gene structures were drawn online with Gene Structure Display Server 2.0 [22]. The CDSs, introns, and UTRs are marked with red boxes, blue lines, and green boxes, respectively. The scale bar is shown at the bottom. c Analysis of conserved domains of the GhEXP proteins. Differently coloured boxes represent different conserved motifs of GhEXP proteins
