| 1 | Identification and mutation analysis of PVY virulence determinant towards the pvr2 and pot-1 resistance alleles in pepper and tomato. | Benoît Moury (Leader) Valérie Ayme Mireille Jacquemond (Leader) Caroline Morel Alain Palloix I. Elisabeth Johansen |
1999 and after | The PVY viral genome-linked (VPg) protein was shown to be the virulence factor corresponding to the pvr2 resistance alleles in pepper and the pot-1 resistance gene in Lycopersicon hirsutum, which encode eukaryotic translation initiation factors eIF4E. | Pepper Tomato |
Potato virus Y Tobacco etch virus |
Capsicum annuum Lycopersicon hirsutum |
pvr2 - pepper pot-1 - tomato |
| 2 | Analysis of the selective pressure exerted on plant virus genomes identifies major epidemiological constraints. | Benoît Moury (Leader) | 2000 and after | The identification of amino acids in plant virus genomes which undergo positive selection allows to understand the role of epidemiological constraints exerted on virus populations (virulence selection, selection for transmission efficiency by vectors, internal vs. external constraints). | Pepper Potato Sugar beet |
Potato virus Y Potato virus A Cucumber mosaic virus Beet necrotic yellow vein virus |
Capsicum Solanum tuberosum Beta vulgaris |
pvr2 - pepper |
