HA2 — Brassica oleracea

Summary

BoHA2 (HA2) on cabbage chromosome 1 encodes a P-type ATPase IIIA family protein with proton-transporting ATPase activity, also annotated for guanylyl cyclase, transmembrane signaling receptor, peptide receptor, voltage-sensitive potassium channel, cis-trans proline isomerase, phosphatase, nucleotide binding, magnesium binding, calmodulin binding, transmembrane receptor protein serine/threonine kinase activity, and ATP hydrolase activity. It is associated with proton export across the plasma membrane, cell pH regulation, response to pH, very-long-chain fatty acid metabolism, negative regulation of leaf senescence and programmed cell death, phloem transport, leaf vascular tissue pattern formation, and defense responses. The gene is linked to traits including alkali soil sensitivity, photosynthetic rate, water stress and temperature stress responses, bacterial disease response, iron content, root and shoot development, leaf senescence, seed growth, and auxin, brassinosteroid, and abscisic acid sensitivity.
