FRO1 — Cucumis sativus

Summary

CsFRO1 (CSA_6G495720) on cucumber chromosome 6 encodes a protein with ubiquinone reductase activity, Co ion binding, and transmembrane transporter activity, belonging to the NDUFS4-like and NADH_UbQ_FeS_4_mit-like families. The gene is associated with mitochondrial complex I assembly, electron transport chain, and localisation to the respiratory chain complex I, mitochondrial inner membrane, mitochondria, and plastid. It is linked to pH reduction, response to iron and nutrients, induced systemic resistance, ethylene anabolism, cold acclimation, osmotic response, and homeostasis. Phenotypic associations include 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.
