BIK1 — Brassica oleracea var. botrytis

Summary

BoBIK1 (BOLND125_C03P026630.1) on cauliflower chromosome 3 encodes a plant serine/threonine protein kinase with multiple annotated molecular functions including protein kinase activity, transmembrane receptor protein tyrosine kinase activity, and guanylyl cyclase activity. The gene is associated with diverse biological processes such as pattern-triggered immunity signalling, regulation of defence response to bacteria, reactive oxygen species metabolic process, detection of bacteria, autophagy, and anther wall tapetum cell differentiation. It is linked to numerous traits including bacterial blight disease resistance, hydrogen peroxide content, brassinosteroid content, lignin biosynthesis, phosphorus uptake, root hair length, and seedling hypocotyl length. The protein localises to the plasma membrane, endosome, plastid, mitochondria, and plasmodesmata. Studies of related genes in other species connect the family to flagellin perception, antibacterial resistance, and salt resistance.
