SHD — Triticum turgidum subsp. durum

Summary

TRITD5AV1G058920 (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, vesicle organization, protein secretion, and protein stabilization. It has been linked to numerous agronomically important traits including grain weight, seed set percent, seed viability, flowering time, maturity time, pollen fertility, and responses to high temperature stress, abiotic stress, bacterial disease, and insect damage. Additional associations include root development, seedling growth, chloroplast development, and jasmonic acid content. Studies of related Hsp90 family members in other species connect this gene family to thermotolerance, disease resistance, plastid function, and thylakoid membrane homeostasis.
