SHD — Triticum turgidum subsp. durum

Summary

TRITD5BV1G142670 (symbol SHD) on durum wheat chromosome 5B encodes a heat shock protein 90 (Hsp90) family member with an Hsp90-like ATPase domain, and is annotated as an ATP-dependent protein folding chaperone. The gene is associated with chloroplast and thylakoid membrane organization, vesicle organization, protein secretion, and de-etiolation. It has been linked to traits including grain weight, seed set percent, seed viability, flowering time, maturity time, pollen fertility, root development, and responses to high temperature, bacterial disease, insect damage, and abiotic stress. Additional associations include salt and ethylene responses, thylakoid membrane integrity, and chloroplast development. Studies of related genes in other species link the family to thermotolerance, mitochondrial function, and disease resistance, and to thylakoid membrane homeostasis.
