1 Sunflower Genome Consortium Annual Meeting Nicolas Langlade INRA Toulouse Sunflower Genome Consortium San Diego, January

2 INRA participation Sunflower Genome Consortium San Diego, January BAC libraries o Preparation CNRGV (H. Bergès, A. Bellec) o BAC-end sequencing LIPM Ultra High Density Genetic map – SFP using Affymetrix microarrays – Genotyping by sequencing – AXIOM map Genome annotation – Transcriptome sequencing – Transcriptome annotation – Genome annotation per se J. Gouzy, S. Carrère, N. Langlade, S. Muños, P. Vincourt

3 INRA participation Sunflower Genome Consortium San Diego, January BAC libraries Preparation -CNRGV (Centre National de Ressources Génomiques Végétales) H. Bergès, A. Bellec 3 BAC librairies HA412-HO BAC-end sequencing -LIPM J. Gouzy, P. Vincourt, S. Muños, N. Langlade, B. Mayjonade Development of a method to perform high-troughput BAC-end sequencing First experiment: BAC-ends are there but too much contamination

4 INRA participation Sunflower Genome Consortium San Diego, January Ultra High Density Genetic map – Genotyping SFP using Affymetrix microarrays P. Vincourt, S. Muños, Y. Lippi, N. Langlade, B. Mayjonade – 105 RILs from XRQxPSC8 population – >3000 mkrs – ~6000 cM  Not used
