IFR — Cicer arietinum

Summary

GmIFR on chickpea chromosome 11 encodes a PCBER-like protein with NmrA-type/isoflavone reductase superfamily and NmrA-like domains, and exhibits 2'-hydroxyisoflavone reductase activity, an oxidoreductase acting on NAD(P)H with oxygen as acceptor. The gene is associated with defense response, systemic acquired resistance, response to insects, nodulation, nitrogen fixation, root development, auxin transport, and auxin metabolism. It is linked to lignan and phenylpropanoid anabolism, phytoalexin biosynthesis, medicarpin and maackiain biosynthesis, and secondary metabolism. The encoded protein localizes to the cytoplasm. GmIFR has been connected to seed coat color. Studies of related genes in other species link the family to root volume and root length.
