P-7 Impact of human selection on the allelic diversity of genes involved into the anthocyanin pathway A. Fournier-Level 1 , L. Le Cunff 2 , T. Lacombe 1 , J-P. Péros 1 , A. Dereeper 1 , B.

This* 1 1 UMR DIAPC INRA-Montpellier Supagro, Montpellier, France; 2 UMT Geno Vigne, IFV- INRA-Montpellier Supagro, Montpellier, France *Corresponding author: this@supagro.inra.fr Berry skin colour, and indirectly the anthocyanin content, is probably one of the agronomical traits most easily selected by human during the history of the grapevine. Consequently the anthocyanin biosynthesis pathway has very interesting features for the study of gene network evolution. Moreover, the structural genes involved in this pathway are identified and characterized and regulatory genes (VvMybAs) of this pathway are also known. Our recent data suggest that the genetic determinism of the total variation of anthocyanin content, and by extension the berry skin colour, in cultivated grapevine is rather due to few mutations within the sequences of the regulatory VvMybAs genes than mutations in anthocyanin structural genes. We have sequenced the VvMybAs genes on a core-collection of cultivated grapevine in order to understand the evolution of the genes at the allelic level and to identify the order of emergence of the principal mutations linked with the anthocyanin content. Secondly, we have sequenced the anthocyanin structural genes on another sample consisting of Vitis Vinifera L. (cultivated and wild) and other species of Vitis to identify the direct and indirect impact of human selection in these genes. These studies showed that berry color-associated mutations evolved from wild black alleles to a pink allele (SNP variation in coding sequence of VvMybA2) and to the white one (Insertion of Gret1 in the promoter of VvMybA1). We have also identified a significant link between the positions of genes in the anthocyanin pathway and their level of divergence. More surprisingly, comparison between values of Tajima’s D and Fay and Wu’s H of the wild and cultivated samples for each gene showed a different impact of the selection pattern and different selected targets within these two samples. This analysis is an interesting example for developing this kind of study at a whole genome level. 83 
P-8 Monoterpene levels in different grapevine (Vitis vinifera L.) cultivars and clones during fruit ripening M. Nitsch*, M. Hey, E. Ruehl, O. Bitz Geisenheim Research Center, Geisenheim, Germany *Corresponding author: m.nitsch@fa-gm.de Terpenes are widespread in the plant kingdom with different functions like pest protection and attraction of insects to pollinate flowers. In white wine monoterpenes largely determine the characteristic aroma profile of a fruity and flowery grape variety. In previous studies authors could identify grape varieties by means of twelve monoterpenes and divide them into three aromatic classes: (1) varieties with a high aromatic Muscat related aroma, (2) with a fruity Riesling-related aroma and (3) varieties with a neutral bouquet [1]. The objective of this study was to characterize and compare the monoterpene contents and seasonal variation of different grape varieties and clones. Grapes of aromatic, less and nonaromatic varieties were collected during ripening periods in 2007, 2008 (2 sampling dates, respectively) and 2009 (5 sampling dates: from July 15 to October 5) at the Geisenheim Research Center. Free and glycosidic bounded monoterpenes were extracted with a solidphase- extraction-method (SPE) using Strata-x (Phenomenex)-cartridges. Glycosides were enzymatically hydrolysed and extracts were analysed by GC/MS. In this study the focus was on the monoterpenols linalool, nerol, geraniol and α- terpineol, the furanoside and pyranoside cis/trans isomers of linalooloxide, the aldehydes neral and geranial plus two diendiols. Results show large differences between cultivars and in particular two clones of “Roter Traminer”. Highest contents were found in grapes of “Siegerrebe” and cultivars of Muscat varieties like “Morio Muskat”. Only traces of monoterpenes were found in “Dornfelder” and “Chardonnay 1 Gm”. During ripening linalool increased significantly in most cultivars, while α-terpineol levels varied only slightly with time. 84
