PR1 — Triticum aestivum

Summary

TRAESCS2D02G317800, designated PR1 on bread wheat chromosome 2D, encodes a Bet v I/Major latex protein domain-containing protein belonging to the Bet_v_I/MLP family. The product exhibits abscisic acid binding, protein phosphatase inhibitor activity, and signaling receptor activity. This gene is associated with diverse biological processes including protein repair, thiamin metabolism, cell wall thickening, actin depolymerization, demethylation, digestion, fatty acid and glutathione metabolism, virus-induced PTGS, photorespiration, phenylpropanoid metabolism, stomatal closure, photomorphogenesis, and nitric oxide storage. It localizes to the cytoplasm and nucleus. PR1 is linked to several agronomically important traits: anther length, yield, grain yield, plant height, chlorophyll content, and tolerance to salinity and drought. Related genes in other species are linked to black point incidence in Fusarium.
