SUNN — Medicago truncatula

Summary

MTR_4G070950 (symbol SUNN) in barrel medic (Medicago truncatula) chromosome 4 encodes a transmembrane receptor protein kinase with serine/threonine kinase activity and ATP binding. The gene is associated with nitrogen fixation, meristem development, organogenesis, floral organ development, regulation of floral meristem size and meristem organisation, auxin polar transport, gametophyte development, megasporogenesis, callus formation, appressorium formation, actin depolymerization, cytokinin anabolism, peptide modification, and responses to nutrient and nitrate. It is linked to nitrogen content, phosphorus uptake, lateral root length, and root length. The product localises to the membrane, plasmalemma, and extracellular region. Studies of related genes in other species connect the family to regulation of meristem size and organ development.
