TH7 — Triticum turgidum subsp. durum

Summary

TRITD2AV1G123680, also known as TtTH7, encodes a thioredoxin H-type-like protein with oxidoreductase activity acting on a sulfur group of donors with disulfide as acceptor, and protein-disulfide reductase activity. This durum wheat gene on chromosome 2A is associated with diverse biological processes including regulation of defence responses to bacteria and insects, systemic acquired resistance, salicylic acid and jasmonic acid mediated signalling pathways, and response to hypoxia. It has been linked to numerous agronomic traits such as wheat powdery mildew, stripe rust, and common root rot disease responses, as well as drought sensitivity, aluminum response, and leaf senescence. The gene product localises to multiple cellular compartments including the nucleus, chloroplast stroma, endoplasmic reticulum, and plasmodesmata. Studies of related genes in other species connect the family to pathogen resistance, salt tolerance, and grain yield.
