CYR1 — Triticum aestivum

Summary

TRAESCS2A02G002500 (TaCYR1) on wheat chromosome 2A encodes a protein with Znf_SUZ12, EMF2-like_DUF7651, and Polycomb_protein_VEFS-Box domains, annotated with histone H3K27 trimethylase activity, chromatin binding, and transcription corepressor binding. It is associated with PcG protein complex localization and epigenetic programming in the endosperm. The gene is linked to photoperiodism, regulation of long-day photoperiodism flowering, and the vegetative-to-reproductive phase transition, as well as seed, endosperm, and embryo development traits. Associations include yield, leaf and inflorescence morphology, and responses to wheat stripe rust and aphids. Related genes in other species connect the family to floral initiation, vernalization response, root architecture, and pathogen susceptibility.
