LKR — Cicer arietinum

Summary

CaLKR (LOC101500267) on chickpea chromosome 7 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, glucose metabolism, and homeostasis, and its product localizes to mitochondria and the cytosol. Studies of related genes in other species link the family to lysine catabolism, seed germination, mitochondrial function, and stress responses including drought recovery, osmotic stress tolerance, salt tolerance, and ABA sensitivity. The family has also been connected to traits such as nitrogen content, germination rate, stomatal resistance, salt response, seed growth and development, and drought tolerance.
