RLK7 — Medicago truncatula

Summary

MTR_3G110860 (RLK7, also known as SUNN) in barrel medic (Medicago truncatula) encodes a transmembrane receptor serine/threonine kinase with leucine-rich repeats, belonging to the plant LRR-RLK family. The gene product exhibits peptide receptor activity, protein kinase activity, and ATP binding. RLK7 is associated with nitrogen fixation, meristem development, floral organ development, organogenesis, and regulation of floral meristem size. It is associated with nitrogen content, phosphorus and nitrate uptake, root length, lateral root initiation and spacing, plant growth, and drought stress response. Additional associations include pathogen resistance, salt tolerance, oxidative stress tolerance, stomatal closure, water transport, and germination speed. The gene is also linked to callus formation, shoot regeneration, and pollen development. Studies of related genes in other species link the family to immunity, root growth inhibition, and hydrogen peroxide diffusion.
