HA1 — Nicotiana attenuata

Summary

A4A49_16612 (HA1, also known as PMA1) in coyote tobacco (Nicotiana attenuata) encodes a P-type ATPase (EC 7.1.2.1) with cation-transporting, proton-transporting, and P-type ATPase activities, as well as transmembrane signaling receptor, guanylyl cyclase, and peptide receptor activities. This gene is associated with proton export across the plasma membrane, vacuolar acidification, cell pH regulation, nitrate import, TOR signaling, very-long-chain fatty acid metabolism, proanthocyanidin anabolism, and response to pH and calcium ions. It has been linked to traits including alkali soil sensitivity, manganese sensitivity, iron content, water stress response, bacterial disease response, photosynthetic rate, stomatal closure, root hair development, drought response, salt resistance, anther development, pollen tube growth, plant height, and growth rate. The gene product localizes to the plasma membrane, tonoplast, ER membrane, and plant-type vacuole.
