HA1 (TRAESCS2D02G503000) — triticum aestivum

Summary

TRAESCS2D02G503000 (TaHA1) on wheat chromosome 2D encodes a P-type ATPase with cation-transporting ATPase activity (EC 7.1.2.1) and is associated with proton export across the plasma membrane, vacuolar acidification, and cell pH regulation. The gene is linked to saline-alkali stress tolerance, seed coat development, negative regulation of leaf senescence, and proanthocyanidin anabolism. TaHA1 has been connected to traits including wheat stripe rust disease response, days to heading, high temperature stress response, iron content, nitrate uptake, root hair formation, and grain development. It is also associated with plant immunity, pathogen defense, and PAMP-triggered immunity. Related genes in other species link the family to growth rate, touch response, grain traits, and alkaline stress tolerance.
