HSP83 — Triticum turgidum subsp. durum

Summary

TRITD0UV1G009860, symbol HSP83 and also known as TtHSP90, encodes a protein with ATP-dependent protein folding chaperone activity, DNA polymerase activity, protein kinase activity, transcription regulator activity, and cis-trans proline isomerase activity. It is associated with cellular thermotolerance, inhibition of cellular response to heat stress, UV protection, base-excision repair, non-homologous end joining, nucleotide excision repair, cellular response to brassinosteroid stimulus, positive regulation of autophagy, root hair cell differentiation, and quiescent center organization. The gene is linked to traits including maturity time, reproductive growth time, temperature stress response, high temperature stress response, starch grain synthesis, photoperiod-sensitive flowering time, shoot axis branching, stamen length, pollen fertility restoration, and responses to auxin, ethylene, gibberellic acid, and brassinosteroids. It localizes to the perinuclear region, chloroplast outer membrane, ER lumen, and SCF complex. Studies of related genes in other species link the family to thermotolerance, drought memory, male fertility, and pathogen resistance.
