SHD — Triticum turgidum subsp. durum

Summary

TRITD5AV1G154160 (symbol SHD) on durum wheat chromosome 5A encodes a heat shock protein 90 (Hsp90) family member with an Hsp90-like ATPase domain and ATP-dependent protein folding chaperone activity. This gene is associated with chloroplast and thylakoid membrane organization, protein stabilization, vesicle organization, and de-etiolation. It has been linked to grain weight, seed set percent, seed viability, flowering time, maturity time, pollen fertility, root development, and seedling growth traits. Associations also include responses to high temperature stress, abiotic stress, bacterial disease, insect damage, and chlorate, as well as jasmonic acid content, and floral organ, inflorescence, and vascular tissue morphology. Studies of related genes in other species link the family to mitochondrial function, thermotolerance, and broad-spectrum disease resistance, as well as thylakoid membrane homeostasis.
