HVA1 (TRAESCS1B02G381500) — triticum aestivum

Summary

TRAESCS1B02G381500, also known as HVA1 or WRAB18, encodes the WRAB18-201 protein on bread wheat chromosome 1B. The gene is associated with abiotic stress tolerance, including cold stress tolerance, and ABA responsiveness. Annotated ontology terms link it to plastid localization, protein unfolding and folding, galactose and glutathione metabolism, protein oligomerization, ER stress response, regeneration, response to high light intensity, hydrogen peroxide, and stomatal movement. It is also connected to cold and heat acclimation, seed germination, and embryogenesis. The gene is associated with numerous agronomic traits, including grain weight, grain yield, grain protein content, plant height, spike length, anthesis time, seed dormancy, sprouting tolerance, water use efficiency, and tolerance to salinity, drought, and high temperature stress. Studies of related genes in tobacco link the family to osmotic stress and salt tolerance.
