ELG — Brassica oleracea var. botrytis

Summary

BoELG (BOLND125_C03P084450.1_BOLND125_V1) on cauliflower chromosome 3 encodes a leucine-rich repeat receptor-like kinase with a serine/threonine kinase domain, belonging to the SERK3/BAK1 family. The protein exhibits multiple molecular functions including GTPase inhibitor activity, guanylyl cyclase activity, transmembrane receptor protein serine/threonine kinase binding, and peptide receptor activity. BoELG is associated with immune response-regulating signaling pathways, anti-apoptosis, regulation of autophagy, and reactive oxygen species-mediated programmed cell death. It has been linked to diverse agronomic traits including grain yield, bacterial blight disease resistance, brassinosteroid content, shoot growth angle, lignin biosynthesis, phosphorus uptake, temperature stress response, and plant male sterility. The gene localizes to the endosome, ER membrane, and plasmodesmata. Studies of related genes in other species connect the BAK1 family to cell death control, bacterial disease resistance, oxidative burst, and organ size regulation.
