Gene and protein structures of G. hirsutum PRC2 core components. a The classification of G. hirsutum PRC2 core components. b Exon/intron distribution of G. hirsutum PRC2 genes. The black boxes and gray lines indicate exons and introns, respectively. c Conserved domain architecture of G. hirsutum PRC2 proteins according to the Pfam prediction. The blue, red, pink and orange boxes represent SET domain, WD40 domain, VEFS-box, and CAF1C_H4-bd domain, respectively
