Phylogenetic relationships, gene structure, and domain compositions of the GhWOX proteins. a A phylogenetic tree was constructed with MEGA 6.0 using the Neighbor-Joining (NJ) method with 1000 bootstrap replicates based on a multiple alignment of the amino acid sequences of the GhWOX proteins. b Exon/intron structures of the GhWOX genes. Exons and introns are represented by blue boxes and black lines, respectively. c Schematic diagram showing the conserved domains in the GhWOX proteins as annotated by InterPro (http://www.ebi.ac.uk/ interpro/scan.html). Different color boxes represent different conserved protein motifs
