FRD1 — Cicer arietinum

Summary

CaFRD1 (LOC101499324) on chickpea chromosome 7 encodes a protein with iron chelate reductase activity, NAD(P)H oxidase H2O2-forming activity, peroxidase activity and calcium ion binding. The protein contains Fe3_Rdtase_TM_dom, FAD-binding and FNR_nucleotide-bd domains. It is associated with siderophore-iron import, multicellular organismal iron ion homeostasis, NO storage, response to bacteria, and localises to the plasmalemma and nucleus. CaFRD1 is linked to photosynthetic rate, iron acquisition, iron deficiency tolerance, chilling tolerance, iron concentration, iron uptake, metal ion homeostasis, disease resistance, root growth under iron deficiency, and uranium response. Related genes in other species link this gene family to iron metabolism, chlorophyll content, root system iron content, net photosynthetic rate, leaf chlorosis, cadmium concentration, lateral root number, and oxidative stress response.
