Identification and characterization of the main seed potato pathogens

More than 40 pathogens are accounted for in the seed potato certification scheme. The intensification of commercial exchanges, climate change and changes in cultivation practices increase the risk of the introduction and/or evolution of pathogens leading to the spread of new populations like, for example, viral variants of PVY species :(PVYNTN, PVYN-W) or Dickeya solani for bacterial species.

Knowledge of pathogen diversity, the development and validation of specific detection tools are three important ways to maintain the health status of the potato crops. To this end, several research projects are underway:

  • A study of biological, serological and/or the molecular pathogen diversity (virus Y, bacteria)
  • A study of the viral molecular determinants of PVY pathogenicity in potato (systemic infection, tuber necrosis) to facilitate the development of innovative tools for viral identification and characterization.
  • The development and evaluation of PCR methods (classical and real-time) for the identification of bacteria (Dickeya, Pectobacterium, Ralstonia solanacearum, Clavibacter michiganensis sepedonicus), fungi (Rhizoctonia solani) and Spongospora subterranea.

 

  • The development and validation of molecular methods for the identification of cyst nematode populations ranging from Heterodera sp. and Globodera sp. genera.
