About the CPPSI Corporate Partnership

CPPSI is a cooperative initiative among seed companies, academia and government agencies who recognize the need for a central administrative entity to develop and distribute reference materials to the scientific community that facilitate consistent plant pathogen strain identification. These reference materials contain differentiating plant host sets (each host contains a known source of resistance), reference plant pathogen strains and instructional white papers for working with a given disease. The focus for reference material development is on diseases for which marketing claims of resistance are made. Centralized administrative management by the CPPSI director ensures that the appropriate plant pathogen strains and hosts are used in developing these reference materials. Known pathogen strains can be correctly identified and previously unknown plant pathogen strains can be discovered based on their phenotypic responses across the differentiating hosts.

CPPSI is a part of the Seed Biotechnology Center (SBC) at UC Davis. The SBC provides operational support, manages the CPPSI finances and administers the seed industry gifted funds. The CPPSI director is an employee of UC Davis.

The CPPSI Corporate Partnership (CPPSI-CP) is structured to share information and educational opportunities. Membership gifts support the development and delivery of reference materials and initiatives. The CPPSI program supports a broad-based and active partnership that keeps industry partners up-to-date and fully engaged with CPPSI education and outreach activities.  

Additional CPPSI membership information can be found on our Membership Information page.
