PR1 (TRAESCS2A02G423300) — triticum aestivum

Summary

TRAESCS2A02G423300 (symbol PR1) on bread wheat chromosome 2A encodes a protein containing a Bet_v_I allergen domain, a Bet_v_I/MLP domain, and a START-like domain superfamily, with abscisic acid binding, protein phosphatase inhibitor activity, and signaling receptor activity. This gene is associated with defense response, ABA signaling, photomorphogenesis, digestion, virus-induced PTGS, phenylpropanoid metabolism, and protein synthesis, and its product localizes to the cytoplasm and nucleus. It is linked to chlorophyll content and resistance to corn earworm. Studies of related genes in other species connect the family to grain yield, plant height, seed germination, crop stand, anthocyanin content, hydrogen peroxide content, black point incidence, ECB resistance, armyworm response, salt tolerance, and resistance to fall armyworm.
