BIK1 — Brassica oleracea var. botrytis

Summary

BoBIK1 (BOLND125_C04P008280.1_BOLND125_V1) on cauliflower chromosome 4 encodes a plant serine/threonine protein kinase with multiple annotated molecular functions including guanylyl cyclase activity, NAD(P)H oxidase H2O2-forming activity, peptide receptor activity, transmembrane receptor protein tyrosine and serine/threonine kinase activities, and steroid, SNARE, and histone H2AS1 kinase binding. The gene is associated with pattern-triggered immunity signalling, defence response to bacteria, reactive oxygen species metabolism, callose deposition, autophagy regulation, and detection of bacteria. It has been linked to traits including bacterial blight disease resistance, hydrogen peroxide content, brassinosteroid and gibberellin biosynthesis, lignin biosynthesis, phosphorus uptake, aluminium and temperature stress responses, root and shoot elongation, stamen length, and leaf and inflorescence development. The protein localises to the plasma membrane, endosome, Golgi, plastid, mitochondria, nucleolus, and plasmodesmata.
