HA1 — Cucumis sativus

Summary

CsHA1 (HA1) on cucumber chromosome 1 encodes a P-type ATPase with cation-transporting ATPase activity, classified as EC 7.1.2.1, and is annotated with P-type potassium:proton and sodium transporter activities, as well as transmembrane signaling receptor, guanylyl cyclase, and peptide receptor activities. The gene is associated with proton export across the plasma membrane, vacuolar acidification, cell pH regulation, potassium ion export, nitrate import, and response to pH. It has been linked to traits including alkali soil sensitivity, stamen number, manganese sensitivity, root volume, iron content, plant dry weight, water stress response, photosynthetic rate, bacterial disease response, and auxin sensitivity. Related genes in other species connect the family to growth rate, root hair development, pollen tube growth, pathogen defense, drought response, salt resistance, and anther development.
