ELG — Brassica napus

Summary

BnELG (also known as BnBAK1, BnSERK3) on chromosome C03 of oilseed rape encodes a protein with leucine-rich repeat and serine/threonine kinase domains, and is annotated with GTPase inhibitor, guanylyl cyclase, and peptide receptor activities. The gene is associated with immune response-regulating signaling pathways, including upregulation of cellular defense and downregulation of immune responses, as well as putrescine and polyamine metabolism, reactive oxygen species-mediated programmed cell death, and carbohydrate homeostasis. It is linked to grain yield, bacterial disease resistance, brassinosteroid content, submergence tolerance, lignin biosynthesis, and responses to aphids, temperature stress, aluminum, and UV light. Localization evidence connects the product to the endosome, ER membrane, plasmodesma, and heterotrimeric G-protein complex. Studies of related genes in other species link the family to cell death control, bacterial disease resistance, organ size, and waterlogging tolerance.
