    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract Potato (Solanum tuberosum) is the world’s third-largest food crop. It severely suffers from late blight, a devastating disease caused by Phytophthora infestans. This oomycete pathogen secretes host-translocated RXLR effectors that include avirulence (AVR) proteins, which are targeted by resistance (R) proteins from wild Solanum species. Most Solanum R genes appear to have coevolved with P. infestans at its center of origin in central Mexico. Various R and Avr genes were recently cloned, and here we catalog characterized R-AVR pairs. We describe the mechanisms that P. infestans employs for evading R protein recognition and discuss partial resistance and partial virulence phenotypes in the context of our knowledge of effector diversity and activity. Genome-wide catalogs of P. infestans effectors are available, enabling effectoromics approaches that accelerate R gene cloning and specificity profiling. Engineering R genes with expanded pathogen recognition has also become possible. Importantly, monitoring effector allelic diversity in pathogen populations can assist in R gene deployment in agriculture
