Sujet principal : By bringing evolutionary biology, community ecology and molecular microbiology together, we aspire to unveil the role of phages in the ecology and evolution of plant pathogenc bacteria and to advance their development as biocontrol agents in agriculture. We currently work with phages of 3 model systems (bacteria and diseases to be targeted.

  1. Pseudomonas syringae : ubiquitous plant pathogen, damaging a large variety of crops including fruit and nut trees, vegetables and ornamentals.

  2. Erwinia amylovora : responsible of fire blight, increasingly affecting apple and pear orchards.

  3. Ralstonia solanacearum : produces bacterial wilt, a world-wide disease specially problematic in tropical areas.
