CKR1 — Cucumis sativus

Summary

CSA_6G445230 (CKR1, also known as CsEIN2) encodes an uncharacterized protein of the NRAMP family, with annotated activities including C2H4 receptor activity, ethene binding, histidine kinase activity, dual-specificity protein kinase activity, and manganese/iron ion transmembrane transporter activity. The gene is associated with sex differentiation, ethylene-mediated signaling, jasmonic acid/ethylene-dependent systemic resistance, detection of ethylene stimulus, response to carbon starvation, regulation of seedling and root development, cell wall thickening, and cellular iron and manganese ion homeostasis. It localizes to the ER membrane, plasmalemma, cytosol, and nucleus. CKR1 is linked to fruit ripening, fruit shape and color, leaf senescence, seed yield and dormancy, root hair length, lateral root length, stem elongation, photosynthetic rate, stomatal resistance, anthocyanin content, temperature stress response, aphid response, herbicide sensitivity, and aluminum stress tolerance. Studies of related genes in other species link the family to ethylene signal transduction, osmotic stress tolerance, iron deficiency response, and disease resistance.
