OPT3 — Pisum sativum

Summary

PsOPT3 (PSAT4G003000) on garden pea chromosome 4LG4 encodes an oligopeptide transporter (OPT) family protein with transition metal ion and oligopeptide transmembrane transporter activity. The gene is associated with xylem-to-phloem iron transport, cellular monoatomic cation homeostasis, and multicellular organismal iron ion homeostasis. It localises to the plasmodesma, membrane, cytosol, plasmalemma, and cytoplasm. PsOPT3 is associated with iron homeostasis, cadmium distribution and partitioning, iron acquisition and acquisition gene expression, iron mobilisation, and disease resistance. Related genes in other species are linked to iron, copper, and metal transport, embryo development, seed iron accumulation, cadmium accumulation in seeds, and metal homeostasis.
