LKR — Brassica juncea

Summary

BJUB05G58000S (BjLKR) 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, pigment metabolism, autotrophy, detoxification, and the TCA cycle, and its product localises to mitochondria and the cytosol. BjLKR has been linked to chlorophyll content and root length. Related genes in other species are associated with lysine catabolism, seed germination, plant growth, mitochondrial function, and stress responses including osmotic and salt tolerance, as well as traits such as drought recovery, plant height, stem diameter, and seed development.
