LRR — Medicago truncatula

Summary

MTR_3G027940, designated MtLRR, encodes a leucine-rich repeat (LRR) domain-containing protein with enzyme inhibitor activity, nucleotide binding, and transmembrane receptor serine/threonine kinase activity. In barrel medic, this gene is associated with diverse biological processes including nitrogen fixation, lateral root development, stomatal complex morphogenesis, UV protection, metabolic burst, hypersensitivity, and upregulation of defense responses to bacteria. It is linked to traits such as stomatal resistance, root length, and salt tolerance, and to phenotypes involving DNA damage repair. The encoded protein localizes to the ER membrane, apoplast, plasmalemma, and nucleus. Studies of related genes in other species connect the LRR family to seed weight, seed size, chlorophyll content, drought tolerance, and days to flowering.
