RLK — Medicago truncatula

Summary

MTR_4G094958 (MtRLK) on barrel medic chromosome 4 encodes a receptor-like kinase (RLK) with transmembrane receptor serine/threonine kinase activity, protein kinase activity, and signaling receptor activity, belonging to the PRK1-6/SRF4-like family with leucine-rich repeats. The gene is associated with nitrogen fixation, lateral root development, post-embryonic plant organ development, regulation of floral meristem size, specification of floral organ number, stomatal complex morphogenesis, ovule development, heat acclimation, and response to salt. It is linked to hormone-mediated signaling, ectodomain cleavage, and regulation of cell growth. Related genes in other species are associated with immunity, low nitrogen stress tolerance, and traits including seed weight, seed size, plant height, root length, chlorophyll content, and photochemical quenching. The encoded protein localizes to the membrane and extracellular region.
