HA2 — Brassica oleracea

Summary

BoHA2 (HA2, AHA2) on cabbage chromosome 7 encodes a P-type ATPase with proton-transporting ATPase activity, calmodulin binding, and additional annotated molecular functions including guanylyl cyclase, transmembrane signaling receptor, and protein kinase activities. The gene is associated with proton export across the plasma membrane, cell pH regulation, response to pH, and proton transmembrane transport. It is linked to negative regulation of leaf senescence, downregulation of programmed cell death, regulation of defense response, and response to molecules of bacterial origin. Associations with agronomically relevant traits include photosynthetic rate, water stress response, bacterial disease response, high and low temperature stress responses, oxidative stress response, salt tolerance, iron content, leaf vein morphology, root development, seed growth, and brassinosteroid, auxin, and abscisic acid sensitivity. Related genes in other species are linked to cell elongation, root growth, drought tolerance, and plant immunity.
