The U.S. Department of Agriculture (USDA), Agricultural Research Service (ARS), Crop Improvement and Protection Research Unit in Salinas, CA is recruiting for a post-doctoral Research Plant Pathologist, GS-11 position (approximately $71,000 Per Year), to study the obligate root pathogen of sugar beet Polymyxa betae and the viruses it transmits, including Beet necrotic yellow vein virus (BNYVV), which causes a serious root disease of sugar beet. This position requires US citizenship. Primary duties include: 1. Investigation of the virus-vector relationships; 2. Genotyping of P. betae isolates in the culture collection; and 3. Investigation of the population structure of P. betae in the field.

Techniques for droplet digital PCR assays for quantification of P. betae and the primary viruses it vectors have been developed and validated, as have techniques for P. betae propagation. Salinas, CA is located in an area with moderate coastal climate, and only a short drive from the Monterey Peninsula, Big Sur State Park, Pinnacles National Monument, and other attractions.
