CRE1 — Medicago truncatula

Summary

MTR_5G044100, symbol CRE1, on barrel medic (Medicago truncatula) chromosome 5, encodes a protein with cytokinin receptor activity, histidine kinase activity, phosphorelay sensor kinase activity, histidine kinase binding, cytokine binding, hydrolase activity, and metal binding, belonging to the two-component system histidine kinase family and containing a signal transduction response regulator receiver domain. The gene is associated with cytokinin response, nitrogen fixation, nitrogen homeostasis, regulation of chlorophyll catabolic processes, secondary growth, phloem or xylem histogenesis, lateral root development, basipetal auxin transport, auxin anabolism, organogenesis, syngamy, developmental processes, cellular responses to cold and abscisic acid, response to sucrose, downregulation of iron ion transport, and regulation of meristem development. The encoded protein localizes to the plasma membrane, ER membrane, and nucleus. Related genes in other species link the family to cytokinin signaling.
