Advancing grapevine science through genomic research

Abstract

The seminar will examine the complexities and prospects of genomic research on Vitis species, characterize by exceptionally high heterozygosity and common interspecific gene flow. The seminar will showcase case studies highlighting the critical role of diploid genome references in grape research, specifically in areas such as aroma development, disease resistance, and domestication traits. It will also address the emerging focus on pangenomes within the Vitis genus, particularly in the context of genetic studies on naturally interbreeding populations. This is crucial for understanding genes linked to both disease and environmental stress resistance. The seminar will present a super-pangenome of North American Vitis species, constructed from diploid chromosome-scale assemblies, and introduce innovative panGWAS methods for investigating abiotic stress resistance in wild grape populations.

Distribution of photosynthates towards the grapes: effects of leaf removal and cluster thinning applied before veraison in cv. Verdejo

The relationship between grape production and leaf surface is a highly debated aspect in terms of the impact it may have on the composition and quality of grapes, especially in areas that focus their cultivation on high-quality wine. In many occasions, the limitation of the unitary production level in these areas is claimed to be the main factor for achieving high quality levels in the wine, forgetting the importance of the source-sink relationship and other environmental factors and management of the canopy. Taking this consideration into account, this work seeks to know the response of the vine as a whole, and the individual shoot as well, to the application of various alternatives of leaves and clusters removal, carried out in the phase immediately before veraison, in cv. Verdejo, in Spain.
