CRE1 — Medicago truncatula

Summary

MTR_2G067240, also known as CRE1, on chromosome 2 of barrel medic (Medicago truncatula) encodes a protein with a CHASE domain and domains characteristic of two-component system histidine kinases. The gene is associated with cytokinin binding, cytokinin receptor activity, histidine kinase binding, phosphorelay sensor kinase activity, histidine kinase activity, hydrolase activity, metal binding, protein serine/threonine kinase activity, and ATP binding. It is linked to nitrogen homeostasis, downregulation of iron ion transport, regulation of chlorophyll catabolic process, secondary growth, basipetal auxin transport, regulation of meristem development, organogenesis, cellular response to cold, developmental process, histidyl-aspartyl phosphorelay, nitrogen fixation, syngamy, auxin anabolism, phloem or xylem histogenesis, cellular response to abscisic acid stimulus, response to sucrose, auxin transport, and lateral root development. The encoded protein localizes to the endoplasmic reticulum membrane, plasma membrane, and nucleus. Related genes in other species, including CRE1, HK3, HK4, HK5, and HK6, link the family to two-component phosphorelay systems.
