Plastid genomics of Vitis vinifera L. for understanding the molecular basis of  grapevine (Vitis vinifera L.) domestication

Abstract

Over the past decade, numerous scientific studies have utilized advanced next-generation plastid DNA technologies to assess the genetic diversity of grapevine (Vitis vinifera L.) worldwide, aiming for a deeper understanding the possible molecular mechanisms of domestication process. For such studies, it is essential to include both cultivated varieties (Vitis vinifera subsp. vinifera) and their wild ancestors (Vitis vinifera subsp. sylvestris) from all potential distribution and domestication sites, as only by comparing the genetic profiles of cultivated and wild specimens can the potential sites of domestication be identified. The main goal of the presented research was the next-generation sequencing (NGS) of complete plastid genomes mainly from European and Mediterranean wild grapevines, as well as cultivated varieties from Europe and Georgia (South Caucasus), and American and Asian Vitis species, followed by in silico genome assembly and phylogenetic analyses. The results revealed that plastomes of European and Mediterranean wild grapevines predominantly exhibit the so-called GTA haplotype; Portuguese wild grapevines exhibit a new type of ATA plastid haplotype; Plastomes of Asian and American species are distinct from those of European and Mediterranean grapevines and the Rkatsiteli haplotype (AAA) remains genetically unique among the plastomes sequenced to date.

Application of regenerative agriculture to viticulture: The REVINE project

Conventional viticulture improved the quality of production, but the economic costs can be unsustainable. Today, producers need to consider consumers’ demands for healthy, eco-friendly products. Institutions promote sustainable agriculture, with regenerative agriculture being the latest generation of methodologies focused on recovering losses and ensuring future sustainability. The revine project studies regenerative agricultural technology applied in mediterranean countries to provide precise indications for soil processing and effective vineyard treatments.

100 guardians for 100 vines

G.r.a.s.p.o. Is not only the acronym for gruppo di ricerca per la salvaguardia e preservazione dell’originalità viticola di ogni territorio (‘research group for the safeguard and preservation of the originality of every territory’s grapes’), and is not just the italian synonym for ‘raspo’ (‘peduncle’) as treccani dictionary mentions: in the veneto dialect it is the whole bunch of grapes.

Genomic comparison on O. oeni: can l. hilgardii be a novel starter culture in malolactic fermentation?

Malolactic fermentation (MLF) the microbial bioconversion of L-malic acid into L-lactic acid, is a pivotal metabolic process that holds fundamental significance for the quality and organoleptic characteristics of some wines. Oenococcus oeni is considered to be the main player in this conversion, and it is globally used as a starter culture for mlf thanks to his capacity to tolerate the harsh wine environment.
