Plant regeneration via somatic embryogenesis and preliminary trials for the application of the DNA-free genome editing in grapevine cv. Corvina veronese

Abstract

Grapevine (Vitis spp.) is a globally significant fruit crop, and enhancing its agronomic and oenological traits is crucial to meet changing agricultural conditions and consumer demands. Conventional breeding has played a key role in domesticating grapevine varieties, but it is a time-consuming process to develop new cultivars with desirable traits for cultivation.
New plant breeding techniques (NpBTs) offer a potential revolution in grapevine cultivation, and genome editing has shown promise for targeted mutagenesis. The success of these biotechnological approaches relies on efficient in vitroregeneration protocols, particularly through somatic embryogenesis (SE). This method has proven successful in some Vitis species, but its effectiveness varies due to the genotype-dependent nature of many cultivars. Moreover, protoplasts have proven to be particularly suitable for genome editing applications, but protoplasts regeneration remains generally considered inefficient in grapevine.
The focus of this study is to enhance in vitro plant regeneration protocols via SE and isolate and regenerate plants from protoplasts derived from embryogenic calli of the Corvina veronese, a variety economically important in Veneto region. Protoplasts will serve as a platform for DNA-free genome editing using CRISPR/Cas9 to target genes responsible for grapevine susceptibility to powdery and downy mildew. The study includes a preliminary phenotypic characterization of regenerated plants to assess whether gene editing or the regeneration process has influenced their morphology and behaviour compared to plants grown under standard conditions. This research aims to accelerate the development of grapevine varieties with improved traits, addressing the challenges posed by conventional breeding methods.

Reconstructing ancient microbial fermentation genomes from the wine residues of Herod, Roman king of Judea

The fortress of the Herodium, built towards the end of the first century BCE/ante Cristo, on the orders of Herod the Great, Roman client king of Judea, attests the expansion of Roman influence in the eastern Mediterranean. During archaeological excavations of the Herodium in 2017[1], a winery was discovered on the ground floor of the palace, with an assortment of clay vessels in situ, including large dolia – clay fermentation vessels each capable of fermenting up to 300-400 L of wine. Thanks to the recent progresses in the field of paleogenomics[2], we could analyse the organic material consistent with grape pomace at the bottom of these vessels, by extracting and sequencing the DNA using shotgun metagenomics and targeted capture, aiming for enrichment of DNA from fermentation associated microbes.

Lamp – a modern tool for the detection of fungal infections in the vineyard

AIM: Loop-mediated isothermal amplification (LAMP) [1] is a modern technology for fast and sensitive amplification of specific DNA sequences under isothermal conditions. Its simple handling and no need for dedicated equipment together with an evaluation of the amplification event by in-tube detection make this method advantageous and economically affordable for on-site investigations in the industry.

Identifying New Zealand Sauvignon blanc terroirs

The concept of terroir is well established in the ‘old world’ wine industry but its use is still relatively new in New Zealand. Marlborough Sauvignon blanc has become a benchmark

Exploring relationships among grapevine chemical and physiological parameters and mycobiome composition under drought stress

Improving our knowledge on biotic and abiotic factors that influence the composition of the grapevine mycobiome is of great agricultural significance, due to potential effects on plant health, productivity, and wine characteristics. Among the various environmental factors affecting the morphological, physiological, biochemical and molecular attributes of grapevine, drought stress is one of the most severe, becoming increasingly an issue worldwide.

Analyses of a long-term soil temperature record for the prediction of climate change induced soil carbon changes and greenhouse gas emissions in vineyards

The evaluation of the current and future impact of climate change on viticulture requires an integrated view on a complex interacting system within the soil-plant-atmospheric continuum under continuous change. Aside of the globally observed increase in temperature in almost all viticulture regions for at least four decades, we observe several clear trends at the regional level in the ratio of precipitation to potential evapotranspiration. Additionally the recently published 6th assessment report of the ipcc (the physical science basis) shows case-dependent further expected shifts in climate patterns which will have substantial impacts on the way we will conduct viticulture in the decades to come.
