Domestication des Solanacées

Les conséquences de la domestication sur les profils nucléotidiques et d'expression ont été examinées en utilisant des données RNAseq dans un ensemble d'accessions de plantes cultivées et sauvages (http://www.arcad-project.org/, Sarah et al., 2016). Après la tomate, nous avons étendu cette approche à la famille des Solanacées pour mener une approche génomique comparative du poivron, de l'aubergine et des tomates sauvages à fruits vertes afin de tester la domestication convergente. Des données RNAseq ont été produites pour 24 accessions (12 cultures / 12 espèces sauvages) chez les trois espèces. Ainsi, à partir du spectre des frequencies de polymorphismes, nous modéliserons le scénario démographique le plus probable survenu durant la phase de domestication chez ces trois espèces et comparerons ces scénarios entre eux.

Diversité des Prunus

Les collections conservées dans le CRB et dans l’unité sont une ressource précieuse qui peut être exploitée pour : cribler les ressources génétiques pour différents caractères afin d'élargir la base génétique utilisée dans les croisements, y compris les espèces sauvages apparentées; rechercher des génotypes résilients à utiliser en tant que fonds génétiques dans lesquels introgresser des caractères ciblés; étudier la structure et la diversité de nos collections, analyser le polymorphisme des locus d'intérêt; développer des analyses GWAS.
