Novel and improved tools for monitoring and tackling genetic selection in populations of the potato cyst nematode Globodera pallida (PALADAPT)
Project
Project code: JKI-A-08-1258
Contract period: 01.01.2018
- 28.02.2020
Purpose of research: Applied research
Keywords: Globodera pallida, virulence testing, genomic characterization
Globodera pallida and G. rostochiensis are regulated as harmful organisms in the European Union, listed in Annex I, Part A, Section II of Council Directive 2000/29/EC. This new Control Directive establishes the measures to be taken against European populations of potato cyst nematodes in order to determine their distribution, to prevent their spread and to control them. In the last years new populations of G. pallida have emerged due to the intensive usage of plant resistance, that are able to overcome plant resistance. It is the main goal of this EFSA partnering grant to support the interaction between the partner institutes INRA (F), WUR (NL) and JKI and allow for investigations on these new populations. The main goals of this project are as follows:
1. Identifying the center of origin of resistance breaking PCN populations found in Germany and the Netherlands.
2. Developing rapid and reliable methodologies and tools for monitoring spread of virulence in G. pallida in the EU. A standard resistance test for PCN is intended to be used in official schemes for testing new potato varieties for resistance to PCN.
3. Characterizing the fitness of resistance-breaking PCN populations. Trade-offs between virulence (defined as the ability to infect a resistant host) and life-history traits are of particular interest in plant pathogens for an accurate risk assessment and durable management of plant resistances.
4. Towards molecular tools for an accurate virulence monitoring. Determining and cataloging the genomic characteristics for populations of Globodera are critical first steps towards development and effective deployment of cyst nematode resistance.
