TH7 — Triticum turgidum subsp. durum

Summary

TRITD7AV1G279260, also known as TH7, encodes a thioredoxin H-type-like protein with oxidoreductase activity acting on sulfur groups, protein-disulfide reductase activity, and additional annotated functions including kinase activity, enzyme activator and inhibitor activities, and salicylic acid binding. This durum wheat gene on chromosome 7A is associated with diverse biological processes, particularly defense responses: it is linked to regulation of systemic acquired resistance, salicylic acid and jasmonic acid signaling, defense responses to bacteria and insects, and response to microbial phytotoxin. The gene has been connected to numerous agronomic traits including responses to wheat stripe rust, powdery mildew, common root rot, bacterial blight, drought sensitivity, aluminum response, leaf and stem senescence, and oxidative stress. Related genes in other species link the thioredoxin family to systemic acquired resistance, salicylic acid signaling, and disease resistance, as well as to salt tolerance and viral susceptibility.
