HA1 — Cucumis sativus

Summary

CsHA1 (CSA_2G009310) on cucumber chromosome 2 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, and transmembrane signaling receptor activity. The gene is associated with proton export across the plasma membrane, vacuolar acidification, cell pH regulation, potassium ion export, nitrate import, and very-long-chain fatty acid metabolism. It has been linked to traits including alkali soil sensitivity, manganese sensitivity, iron content, root volume, plant dry weight, photosynthetic rate, water stress response, bacterial disease response, brassinosteroid sensitivity, auxin sensitivity, cell elongation, high temperature stress, and stamen and pistil morphology. Localization evidence connects the product to the plasma membrane, tonoplast, ER membrane, nuclear envelope, and plant-type cell wall.
