HA1 — Nicotiana attenuata

Summary

A4A49_39257 (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 activity, and is associated with additional molecular functions including transmembrane signaling receptor, guanylyl cyclase, peptide receptor, and voltage-sensitive potassium channel activities. The 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 is linked to traits including alkali soil sensitivity, stamen number and length, manganese and iron content, water stress and bacterial disease response, leaf vein morphology, shoot growth angle, nitrate uptake, lateral root length, brassinosteroid and auxin sensitivity, cell elongation, arsenic concentration, high temperature stress response, photosynthetic rate, root meristem development, stomatal closure, leaf senescence, and organ identity.
