D3 — Oryza sativa Japonica

Summary

OsD3 (OS05G0222200) encodes an ABCG family transporter with fatty acyl transporter activity, efflux permease activity, and ATP-coupled transmembrane transporter activity. In rice, this gene is associated with sporopollenin biosynthesis, pollen exine formation, cuticle anabolism, suberin biosynthesis, and stem and cotyledon vascular tissue pattern formation. It is linked to pollen fertility, seed growth and development, root development and thickness, shoot branching, disease tolerance, and responses to salinity, osmotic stress, abscisic acid, and cytokinin. The protein localizes to the plasma membrane, Casparian strip, suberin network, periarbuscular membrane, and plasmodesmata. Studies of related genes in other species link the family to cuticular wax export, cutin transport, organ fusion prevention, and salt tolerance.
