Heterologous expression of a pleiotropic drug resistance transporter from Phytophthora sojae in yeast transporter mutants.

A system for the expression of an ATP binding cassette (ABC) transporter from the soybean pathogen Phytophthora sojae is described. Pdr1, an ABC transporter with homology to the pleiotropic drug resistance (PDR) family of transporters, was cloned by primer walking from a P. sojae genomic library.
