FRD1 — Cucumis sativus

Summary

CSA_5G175770 (symbol FRD1, also known as FRO1, FRO3, CsFRD1, CsFRO1, CsFRO2, CsFRO3, FRO2, RBOHD, RbohD, CmRBOHD) on cucumber chromosome 5 encodes a FAD-binding FR-type domain-containing protein with iron chelate reductase, NAD(P)H oxidase H2O2-forming, and peroxidase activities, and binds calcium. It localizes to the plasma membrane and nucleus. The gene is associated with iron import, siderophore-iron import, pH reduction, response to nutrient and iron, multicellular organismal iron ion homeostasis, metabolic burst, auxin anabolism and transport, induced and systemic acquired resistance, ethylene anabolism, stomatal closure, leaf senescence, response to bacteria, and syngamy. It is linked to traits including plant dry weight, chlorophyll a, photosynthetic rate, low temperature stress response, leaf senescence, seed growth and development, and salt tolerance. Phenotype associations include iron deficiency tolerance and response, oxidative burst, iron concentration, homeostasis and acquisition, cold, chilling, salt and arsenic stress tolerance, disease resistance, root growth under iron deficiency, and uranium response.
