Project
Interaction between plant, soil and nematodes
In the framework of HIP, two projects are focusing on the development of control strategies for PCN to stabilize yield. The focus of the BB1.1 project is on the chemical communication between the host plant and the nematode during the hatching process, the first step in the infection cycle which takes place outside the plant in the soil (see Fig). The focus of the BB3.2 project is on the identification of novel genetic resistance sources from wild potato species that can be used in breeding programs. Resistant genotypes are screened and selected based on the number of cysts/egg masses (un)able to develop scored in the final stage of the infection process (see Fig). Already many genotypes have been found to provide resistance against one or more nematodes isolates/populations. Since, the projects used (partially) the same genetic resources and the comparison of results will contribute to the understanding of the resistance mechanisms. Also additional information is needed on other steps in the infection and hatching process, which are not covered in both current projects, BB1.1 and BB3.2 (knowledge gap and bottleneck). Therefore, the aim of this new module is to close this knowledge gap by expanding and integrating research activities. This will improve the assessment and selection of resistance sources for breeding.
