Phylogenetic analysis showed that cotton <i>PHR</i> genes were classified into five distinct subfamilies. The gene structure, protein motifs and gene expression were further investigated. The <i>PHR</i> genes of <i>G. hirsutum</i> from the same subfamily had similar gene structures, all containing Myb_DNA-binding and Myb_CC_LHEQLE conserved domain. The structures of paralogous genes were considerably conserved in exons number and introns length. The cis-element prediction in their promoters showed that genes were not only regulated by light induction, but also were related to auxin, MeJA, abscisic acid-responsive elements, of which might be regulated by miRNA.
