FRO1 — Cucumis sativus

Summary

CsFRO1 (CSA_2G354640) on cucumber chromosome 2 encodes the NADH dehydrogenase [ubiquinone] iron-sulfur protein 4, mitochondrial, a component of respiratory chain complex I. The gene is associated with ubiquinone reductase activity, transmembrane protein transporter activity, and cobalt ion binding, and is linked to mitochondrial complex I assembly, electron transport, pH reduction, response to iron and other nutrients, ethylene anabolism, induced systemic resistance, cold acclimation, osmotic response, and homeostasis. CsFRO1 localises to the mitochondrial inner membrane and plastid. The gene has been connected to cold tolerance, salt tolerance, osmotic stress tolerance, germination, plant growth, cell wall assembly, photoperiod acclimation, and stress tolerance. Studies of related genes in other species link the family to protein content, low temperature stress response, and reduced cold acclimation with altered leaf morphology.
