HA1 — Cucumis sativus

Summary

CsHA1 (CSA_1G423270) on cucumber chromosome 1 encodes a cation-transporting P-type ATPase N-terminal domain-containing protein with P-type potassium:proton transporter activity, P-type sodium transporter activity, and additional annotated molecular functions including transmembrane signaling receptor activity, guanylyl cyclase activity, and voltage-sensitive potassium channel activity. The gene is associated with proton export across the plasma membrane, vacuolar acidification, cell pH regulation, potassium ion export, nitrate import, and proanthocyanidin anabolism. It is linked to traits including alkali soil sensitivity, manganese sensitivity, iron content, root volume, plant dry weight, water stress response, bacterial disease response, brassinosteroid sensitivity, auxin sensitivity, and stamen and pistil morphology. Associations also include root hair formation and elongation, stomatal movement, drought response, salt resistance, pathogen defense, pollen tube growth, and plant fertility. Studies of related genes in other species connect the family to cell elongation, growth, abiotic stress tolerance, and tuber yield.
