FRD1 — Cicer arietinum

Summary

CaFRD1 (LOC101499003) 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. It belongs to the Fe3_Rdtase_TM_dom and FAD-binding domain families. The gene is associated with siderophore-iron import, multicellular organismal iron ion homeostasis, calcium signaling, NO storage, response to bacteria and heat, and signal transduction. It localises to the plasmalemma and nucleus. CaFRD1 is associated with photosynthetic rate, iron acquisition and deficiency tolerance, chilling tolerance, iron concentration and uptake, metal ion homeostasis, disease resistance, root growth under iron deficiency, and uranium response. Related genes in other species are linked to iron metabolism and chlorophyll content, as well as root system iron content, net photosynthetic rate, leaf chlorosis, cadmium concentration, lateral root number, and salt tolerance.
