HA1 — Cucumis sativus

Summary

CsHA1 (CSA_5G635370) on cucumber chromosome 5 encodes a P-type ATPase classified as EC 7.1.2.1, with annotated molecular functions including P-type potassium:proton transporter activity, P-type sodium transporter activity, cation-transporting ATPase activity, transmembrane signaling receptor activity, guanylyl cyclase activity, and peptide receptor activity. The gene is associated with proton export across the plasma membrane, vacuolar acidification, cell pH regulation, potassium ion export, nitrate import, proanthocyanidin anabolism, very-long-chain fatty acid metabolism, and response to pH, calcium, and iron. It has been linked to traits including alkali soil sensitivity, stamen number, manganese sensitivity, root volume, iron content, plant dry weight, water stress response trait, photosynthetic rate, bacterial disease response, nitrate transport, leaf vein morphology trait, shoot growth angle, brassinosteroid sensitivity, auxin sensitivity, cell elongation trait, arsenic concentration, high temperature stress response, and stomatal complex closure time. Studies of related genes in other species connect CsHA1 to root hair development, pollen tube growth, salt resistance, drought response, pathogen defense, and plant fertility.
