FRD3 — Sorghum bicolor

Summary

SORBI_3003G403000 (SbFRD3) on sorghum chromosome 3 encodes a MATE family transporter with citrate transmembrane transporter activity, metal ion transporter activity, iron channel activity, and antiporter activity. It localizes to the plasma membrane. The gene is associated with cellular and multicellular iron ion homeostasis, metal ion transport, response to phosphate starvation, and response to abscisic acid. SbFRD3 has been linked to grain yield, iron homeostasis, accumulation, transport, and translocation, as well as pollen viability, seed germination, copper tolerance, root growth, and phosphate-dependent root growth. Studies of related genes in other species connect the family to metal homeostasis, aluminum tolerance, iron deficiency response, zinc homeostasis, pollen fertility, and reproductive growth.
