The availability of knowledge of the route of infection and critical plant and microbe factors influencing the colonization efficiency of plants by human pathogenic bacteria is essential for the design of preventive strategies to maintain safe food. This research describes the differential interaction of human pathogenic Salmonella enterica with co...
Microbial plant pathogens impose a continuous threat on global food production. Similar to disease resistance in mammals, an innate immune system allows plants to recognise pathogens and swiftly activate defence. For the work described in this thesis, the interaction between tomato and the extracellular fungal pathogen Cladosporium fulvum serves as...
Cladosporium fulvum (syn. Passalora fulva) is a biotrophic fungal pathogen that causes leaf mould of tomato (Solanum esculentum). Chapter 1 is a “pathogen profile” describing the biology of the pathogen. During growth in the leaf apoplast, the intercellular space surrounding the mesophyll cells, the fungus secretes effector proteins that are though...
During the past decades, an increasing number of new tospovirus species occurring in various agricultural and horticultural crops have been reported. The emergence of new tospoviruses may be attributed to intensified international trading, to increasing problems to control their thrips vectors, but certainly also by better recognition based on new ...
Receptor-like proteins (RLPs) are receptors on the surface of plant cells that are important for the activation of disease resistance. Furthermore, some RLPs are important for plant development. The Arabidopsis genome contains 57 genes encoding RLPs. A genome wide collection of RLP gene knock-out mutants was assembled and functionally analyzed for ...
The potato late blight disease that is caused by the oomycete pathogen Phytophthora infestans is a major threat for potato crops worldwide. In recent years research on oomycete plant pathogens was boosted by the availability of novel genomic tools and resources for several oomycete genera, such as Phytophthora, Hyaloperonospora, Pythium and Aphanom...
Botrytis cinerea can infect more than 200 plant species, including a wide range of economically important crops. During pathogen infection, plants release ethylene and it has been hypothesized that ethylene may predispose host tissue for infection by inducing senescence and ripening. This thesis focused on the roles that ethylene production and per...
Plants are not able to move or escape and have to confront environmental challenges like nutrient and water deprivation, low and high temperatures, and biotic stress imposed by pathogens like viruses, bacteria, fungi, nematodes and insects that all compete for plant nutrient sources. The outcome of a plant-pathogen interaction can vary from mild sy...
Potato (Solanum tuberosum L.) is nowadays the most important non-cereal food crop in the world. It is prone to huge annual losses due to late blight, the disease caused by the oomycete pathogen Phytophthora infestans. Modern management of late blight necessitates the use of multiple resistance (R) genes, which requires efficient pipelines for ident...
Onlangs is de DNA-sequentie van het genoom van Cladosporium fulvum bepaald. Het voornaamste doel daarvan is de identificatie en karakterisering van nieuwe effectors.
