hsp16.9A — Triticum aestivum

Summary

TRAESCSU02G194600 (symbol hsp16.9A, preferred name TaHSP17.4-CI) on bread wheat chromosome NW_025236226.1 encodes an SHSP domain-containing protein with a small heat-shock protein (HSP20-like chaperone) domain and is annotated as a protein folding chaperone. The gene is associated with responses to heat, hydrogen peroxide, ethanol, copper, arsenic, cadmium, and salinity, and with protein folding, homooligomerization, and cell cycle processes. It has been linked to salt tolerance in wheat and to traits including grain texture, grain hardness, whole grain protein content, shoot fresh weight, auxin content, heat tolerance, head wax, and SDS sedimentation. The protein localises to the cytoplasm and nucleus. Studies of related genes in other species connect the family to stress tolerance and chaperone activity.
