CKR1 — Medicago truncatula

Summary

MTR_2G062640 (CKR1) in barrel medic (Medicago truncatula) encodes a protein with C2H4 receptor activity, histidine kinase activity, dual-specificity protein kinase activity, and metal ion transmembrane transporter activities including iron and manganese channel activity. It is associated with ethylene metabolism and signaling, hormone metabolism, cytokinin metabolism, jasmonic acid/ethylene-dependent systemic resistance, regulation of stem cell renewal, post-embryonic root development, seedling development, vacuolar transport, planar polarity, and responses to carbon starvation and hormones. The gene is linked to traits including seed yield, nitrate content and transport, photosynthetic rate, stomatal resistance, root development, lateral root length, cell elongation, anthocyanin content, temperature stress responses, aphid and insect damage responses, and herbicide sensitivity. It localizes to the tonoplast, ER membrane, plasmalemma, and nucleus. Studies of related genes in other species link the family to ethylene signal transduction, fruit ripening, salinity tolerance, iron acquisition, and disease resistance.
