Grape genetic research in the age of pangenomes

Abstract

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.

Cultivation forms and viticulture models adapting to adverse “environmental” conditions

One of the main problems in viticultural production in Istria (Croatia) is a labour shortage in periods of intensive works, mainly during summer, respectively during tourist season.

The French grapevine breeding program resdur: state of the art and perspectives

The French grapevine breeding program for durable resistance to downy and powdery mildew (INRAE-ResDur) was initiated more than 20 years ago to help reduce the heavy use of plant protection products and provide a durable mean to cope with a strong pathogen pressure. This program has now proved to be effective, with about ten new varieties already officially registered. However, there is still a lot to be done (1) to reduce the duration of each breeding cycle, (2) to diversify disease factors’ pyramiding and anticipate emerging diseases, (3) to work towards larger adoption of the new resistant varieties. New breeding schemes incorporating for example genomic prediction of breeding values are being evaluated to accelerate genetic gains, saving cost and time while handling complex traits.

An Ag+ SPE method combined with Deans’ switch heart-cutting MDGC–MS/Olfactometry approach for identifying unknown volatile thiols in wine

Wine aroma is a crucial quality criterion. A multitude of volatile compounds have been identified and correlated to the aroma attributes perceived in wine.

Dalle zonazioni storiche alle “nuove forestazioni storiche produttive vitivinicole” per la valorizzazione delle cultivar e dei prodotti tipici ed originali dei Monti Iblei

Analisi sulle zonizzazioni storiche, sulle produzioni tipiche ed originali e sulla “forestazione classica” per impostare innovative zonazioni vitivinicole e dei prodotti tipici, originali attraverso la “Nuova forestazione storica produttiva”. Le recenti ricerche ed attività svolte sulle zonizzazioni storiche, sulle produzioni tipiche ed originali e sulla “forestazione classica” dei Monti Iblei (Ragusa) (I) hanno permesso di rilanciare le produzioni tipiche ed originali vitivinicole in un innovativo programma integrato tra zonazione (“Grande Zonazione”) e “Nuova forestazione storica produttiva” (“Grande Forestazione Produttiva”) di questo importante territorio.

Influence of withering on valpolicella docgs grapes volatile composition

The blend of grapes used in the production of the four Valpolicella PDOs red wines, namely Valpolicella, Valpolicella Classico Superiore, Recioto della Valpolicella and Amarone della Valpolicella is quite unique, and includes two main varieties Corvina and Corvinone, and other minor varieties. To a very large extent all these grapes are only grown in the province of Verona. One of the main characteristics of Valpolicella is the use of grapes that are submitted to post-harvest withering. The aim of this study was therefore to evaluate the evolution of the free and glycosidically-bound volatile compounds in Corvina and Corvinone grapes under real production conditions.
