Накратко на български

Спонтанните генетични мутации при лозата, като тези при сорта Темпранильо, се анализират, за да се разбере произходът им. Това помага за създаването на сортове, които са по-устойчиви на суша и глобалното затопляне, без да се променява пазарната приемливост на вината.

Fast-forward genomics of somatic variants adaptable to climate change for cultivar innovation in grapevine

Grapevine, with its derived products constitutes, as measured by cultivated area and economic volume, the most relevant fruit crop in the world (7.6 million ha of vineyard and 30.4 billion Euro trade wine value worldwide in 2017). Viti-viniculture is particularly important for the economy of Europe that hosts 50% of the worldwide vineyard. By the time being, winemakers face unprecedented challenges: they must meet a growing demand for quality and recognizable wines, and at the same time, there is a need to make viticulture more sustainable by decreasing the waste of precious resources. In addition, cultivation and production has to become better adapted to current and future climates. Global warming is threatening the production of quality wine in classical winegrowing regions. Increasing temperature and drought episodes alter grape fruit ripening and composition, leading to the production of excessively alcoholic wines that are unbalanced in colour and flavour. Adaptation of the plant material would be a suitable strategy to overcome these challenges. However, this strategy is limited as both conventional breeding and genetic modification result in cultivars that are unlikely to become widely accepted by the wine market in the short-term. A viable alternative is the use of somatic variants that emerge from spontaneous somatic mutations throughout long periods (in many cases even centuries) of clonal propagation of the same grapevine cultivar. The general goal of this project was to improve our understanding of the origin of somatic variation, so that it can be more effectively exploited as a natural source of diversity for the improvement of elite wine cultivars. In this MSCA action we focused on the clonal improvement of Tempranillo, a Spanish cultivar appreciated worldwide for the production of full-bodied red wines. Tempranillo is the most widespread red wine cultivar in the Iberian Peninsula and the third in the world. Natural somatic variants of Tempranillo with ripening features adaptable to quality wine production under predicted future climate have been selected. For this innovation to become feasible, it is necessary to identify the genetic origin of this variation. Knowledge of the causal somatic mutations will enable the development of reliable molecular markers for the identification and protection of selected improved variants. To this end, we proposed the following aims: 1. Produce a de novo-assembled reference genome for Tempranillo. 2. Characterize at the molecular level the somatic variation of Tempranillo clones with ripening phenotypes suitable for quality wine production under warmer climate. 3. Locate the somatic mutations responsible for climate change adaptable phenotypes in selected clones.

Цел на проекта

Grapevine, with its derived products, is the most relevant fruit crop for the European agro-ecosystems, economy and culture. Even more so than for many other crops, climate change is threatening the sustainability of vitiviniculture. Increasing high temperature and drought episodes experienced in traditional European winegrowing regions have already begun to alter grapevine physiology and grape ripening, which translates into a decline in wine quality, particularly in Southern regions. Somatic variants with improved traits that at the same time maintain the attributes that make a varietal wine recognizable are traditionally selected as new clones of grapevine cultivars. Somatic variation is therefore a socially accepted source of diversity that can be exploited to anticipate and adapt production to changing environments and fluctuating consumer demands using more sustainable cultivation systems. However, for this innovation to become feasible through clonal breeding, it is necessary to identify the genetic origin of this variation to guarantee the protection and commercial distribution of selected clones. In this project, somatic mutations leading to climate change adaptable fruit features will be identified for the first time. This will be done by studying ripening variants selected by clonal breeding in Tempranillo, the most relevant cultivar for the vitiviniculture of the Iberian Peninsula and the third most widespread red wine cultivar in the world. Taking advantage of high throughput-sequencing technologies, I will combine cutting edge genomics and fast-forward genetics to pursue the following specific aims: 1) Produce a de novo-assembled reference genome for the Tempranillo grapevine cultivar, 2) Characterize at the molecular level the somatic variation of Tempranillo clones with ripening phenotypes suitable for quality wine production under warmer climate and, 3) Locate the somatic mutations responsible for climate change adaptable phenotypes in these clones
