LKR — Brassica napus

Summary

BnLKR (LKR) on chromosome A01 of oilseed rape (Brassica napus) encodes a bifunctional enzyme with saccharopine dehydrogenase (NADP+, L-lysine-forming) activity, belonging to the LOR/SDH bifunctional enzyme conserved domain family. The gene is associated with L-lysine breakdown, oxidative phosphorylation, ATP anabolism, hormone anabolism, the electron transport chain, TCA cycle, embryogenesis, syngamy, signal transduction, defense response, and response to thirst. The product localizes to mitochondria, cytosol, and cytoplasm. Associations with plant height, stem diameter, and drought tolerance have been recorded. Studies of related genes in other species link the family to lysine catabolism, mitochondrial function, seed germination, and stress responses including salt and osmotic stress tolerance, ABA sensitivity, and chlorophyll content.
