INRA is a public research institute dedicated to agricultural sciences with multidisciplinary expertise in plant and animal. INRA undertakes most of French research on sharka, from virus characterisation to stone fruit tree breeding programmes. INRA is represented in SharCo by two departments addressing the two main areas of the project: virology and molecular genetics.
Key persons involved
- INRA’s Genomics and Pathogenic Properties Development joint research unit (GDPP)
• Dr. Véronique DECROOCQ: plant molecular biologist and geneticist, specialised on the understanding of the interactions of PPV with its hosts, Prunus species and Arabidopsis thaliana. She has been coordinating regional, national and bilateral projects focusing on the resistance to sharka disease.
• Dr Thierry CANDRESSE: virologist specialised on virus strain characterisation and identification of new viruses.
• Dr. Michel RAVELONANDRO: Expertise in molecular virology and plant biotechnology.
- INRA’s Biology and Genetic of Plant/Microbe Interactions for Integrated Protection (BGPI) joint research unit
• Mr. Gérard LABONNE: Specialized on virus vectors (aphids),
• Dr. Sylvie DALLOT: plant virologist expert in Plum pox virus epidemiology,
• Dr Gaël THEBAUD: Epidemiologist with modelling and simulation skills.
- INRA, Fruits and Legumes Genetics and Breeding unit (GAFL)
• Mr J-M AUDERGON is responsible of the apricot breeding programme at INRA, he assumes the animation of the European Apricot working group.
• Thierry PASCAL is responsible of the peach breeding programme at INRA.
• Patrick LAMBERT has in charge the Prunus genomic plateform comprising Marker assisted Selection in apricot and peach.

The three INRA research units are fully equipped with :
- facilities for molecular biology, plant DNA analysis and cloning, that will be dedicated to the manipulation of PPV infectious clones and to the identification of resistance genes and molecular markers,
- facilities for apricot and peach breeding programmes such as experimental orchards,
- type-2 confined greenhouses for PPV phenotyping with local PPV strains
- type-3 greenhouses for confinement of quarantine PPV strains and variants and any experiment involving such isolates.Website
