Epidemiological surveillance of plant pathogens allowing identification of emerging clones escaping control strategies and tracing of bacterial strains are of great importance for integrated plant protection. Ralstonia solanacearum is the causal agent of bacterial wilt one of he most damaging plant bacterial diseases worldwide.
Analyze the genetic diversity of R. solanacearum in South-West Indian Ocean (SWIO) islands and Eastern Africa.
Characterize the evolutionary forces that shape populations of R. solanacearum in these geographic areas.
Evaluate genetic resources for resistance to bacterial wilt (mainly for potato).
Validate molecular diagnostic tools available or under development. And,
set-up an epidemiological surveillance network involving international research and education institutions, professional actors in the agricultural world, and a start-up.
Field surveys in each country (collection of populations).
Molecular characterization of strains.
Genetic structure analysis of populations at different spatial and temporal scales.
Evaluation of genetic resources for resistance to bacterial wilt.
Development and validation of diagnostic tools. And, organization of kick-off and closing meetings and training sessions for knowledge sharing and capacity building both on R. solanacearum and the technologies.
Complete overview of epidemiological situation of R. solanacearum in the SWIO islands and Eastern Africa.
Identification of the migration routes of R. solanacearum.
Identification of bacterial wilt resistance sources.
Dvelopment and adaptation of new effective and reliable diagnostic tools for R. solanacearum.
New epidemiosurveillance network. And, strengthening cooperation between Labex Agro Units, ANSES, CGIARs, SWIO institutions.
