HSP83 — Triticum turgidum subsp. durum

Summary

TRITD2BV1G010840 (HSP83, TtHSP83) on durum wheat chromosome 2B encodes a heat shock protein 90 family member with an HSP90-like ATPase domain, annotated as an ATP-dependent protein folding chaperone with DNA polymerase, transcription regulator, protein kinase, and cis-trans proline isomerase activities, and binding to Hsp90, phosphatidylinositol phosphates, and chromatin. The gene is associated with cellular thermotolerance, inhibition of heat stress response, UV protection, base-excision and nucleotide-excision repair, brassinosteroid and ethylene sensitivity, root hair differentiation, autophagy, chloroplast localization, and the perinuclear region. Traits linked to HSP83 include maturity time, reproductive growth, starch grain synthesis, shoot branching, stamen length, pollen fertility restoration, and responses to temperature, photoperiod, auxin, gibberellin, jasmonic acid, and abiotic stresses. Related genes in other species are associated with thermotolerance, drought memory, male fertility, and pathogen resistance.
