Annotation:
Polycomb repressive complex 1 (PRC1) and 2 (PRC2) play important roles in many biological processes. They regulate gene expression at the epigenetic level by posttranslationally modifying specific histone residues. The identification of the PRC1 and PRC2 core components and their chromosomal location in hexaploid wheat may enable a deeper understanding of developmental processes, including vernalization, in commonly grown winter wheat.

Schematic representation of the conserved protein domain architecture of Polycomb group (PcG) complexes. Homologs of the PRC2 (a) and PRC1 (b) core subunits share highly conserved protein domains among
Arabidopsis thaliana (At),
Hordeum vulgare (Hv),
Triticum dicoccoides (Td) and
Triticum aestivum (Ta).
