Disease resistance in crops is an important aspect of securing global food security. Resistant plants carry immune receptors that sense pathogen invasion often through the recognition of important pathogen virulence factors, known as effectors. Thus, identification and characterization of effectors is important for the fundamental understanding of ...
Plant-pathogenic microbes secrete effector molecules to establish disease on their hosts, whereas plants in turn employ immune receptors to try and intercept such effectors in order to prevent pathogen colonization. Based on structure and subcellular location, immune receptors fall into two major classes; cell surface-localized receptors that compr...
Currently, fungicides are necessary to protect potato crops against late blight, Phytophthora infestans, one of the world’s most damaging crop pathogens. The introgression of plant resistance genes from wild potato species targeted specifically to the late blight pathogen into susceptible potato varieties may alleviate the environmental impact of c...
Potato is affected by several diseases. Although, resistance can be obtained by introgression of major resistance genes from wild species, this has rarely been durable. Hence, other sources of resistance are highly needed. New research with a focus on loss of function mutations has led to the identification of disease susceptibility (S) genes in pl...
Gerbera hybrida is one of the top five cut flowers. It is well-known to people for its variation in flower color and patterning. Gerbera breeding at the moment is done using conventional methods which are based on a phenotypic selection. This has drawbacks in breeding speed and efficiency, especially for complex traits like disease resistance. Gerb...

De biologische aardappelteelt heeft het in 2016 weer zwaar te verduren gehad met de hevige uitbraak van Phytophtora infestans. Door aanhoudende regenval in juni en juli waren veel telers genoodzaakt om hun percelen met aangetaste aardappelen al vroeg in het seizoen te branden. Gecombineerd met de late pootdatum hebben velen een (te) lage opbrengst ...
Projections on the impact of climate change on agricultural productivity foresee prolonged and/or increased stress intensities and enlargement of a significant number of pathogens habitats. This significantly raises the occurrence probability of (new) abiotic and biotic stress combinations. With stress tolerance research being mostly focused on res...
Powdery mildew (PM) is a major fungal disease that threatens thousands of plant species. PM is caused by Podosphaera leucotricha in apple and Erysiphe necator in grapevine. Powdery mildew is controlled by frequent applications of fungicides, having negative effects on the environment, and leading to additional costs for growers. To reduce the amoun...
Doel van dit onderzoek is het ontwikkelen van een systeemaanpak voor de beheersing van meeldauw door de inzet van groene producten (laag-risico profiel) die een bijdrage leveren aan het versterken van natuurlijke afweerreacties. Poster van het PlantgezondheidEvent 2016.
