Grape genetic research in the age of pangenomes


Genetic approaches towards better Grape & Wine Quality
Combined improvements in sequencing technologies and assembly algorithms have led to staggering improvements in the quality of grape genome assemblies. Completely phased haplotypes have been instrumental to advances in grape research due to high heterozygosity, structural variation, and gene content variability across homologous chromosomes.  Phased assemblies of grape genomes have revealed genomic complexities that were inaccessible in previous haploid representations, such as haplotype-specific structural variation events, trait-associated alleles, and allele-specific gene expression and methylation. The availability of wild and cultivated grape diploid genome references containing the genes and alleles underlying traits of interest has been instrumental in dissecting the genetic basis of disease resistance, flower sex determination, aroma, and flavor. User-friendly web platforms, like www.grapegenomics.com, have played a critical role in rapidly and broadly sharing genomic data and tools, and foster multidisciplinary collaborations and progress in grape research.

Significance of factors making Riesling an iconic grape variety

Riesling is the iconic grape variety of Germany and accounts for 23% of the German viticulture acreage, which comprises 45% of the worldwide Riesling plantings. Riesling wines offer a wide array of styles from crisp sparkling wines to highly concentrated and sweet Trockenbeerenauslese or Icewines. However, its thin berry skin makes Riesling more vulnerable to detrimental environmental threats than other white wine varieties.

Winemaking techniques and wine tasting methods at the end of the Middle Ages

Les pratiques de vinification et de dégustation du vin sont souvent perçues, à travers un discours marketing très puissant, sous l’angle d’une tradition millénaire qui perdure depuis le Moyen Âge. En Bourgogne, il est courant de rattacher les racines de ces pratiques à l’activité des institutions ecclésiastiques qui possédaient d
