Phylogenetic relationships and gene structures of wheat HD-Zip genes. a Phylogenetic tree of 113 full length HD-Zip proteins from wheat were constructed by MEGA 6.0 using the Neighbour-Joining (NJ) method with 1000 bootstrap values. b Exon/intron structures of wheat HD-Zip genes. Exons and introns are represented by purple boxes and grey lines, respectively. c The distribution of intron numbers between four distinct HD-Zip subfamily of wheat
