The grapevine (Vitis vinifera L.) floral transcriptome in Pinot noir variety: identification of tissue-related gene networks and whorl-specific markers in pre- and post-anthesis phases.

Hortic Res 2021 Sep 1;8(1):200. Epub 2021 Sep 1.

Department of Agronomy, Food, Natural Resources, Animals and Environment (DAFNAE), University of Padova, Campus of Agripolis, V. le dell'Università 16, 35020, Legnaro, Padova, Italy.

The comprehension of molecular processes underlying the development and progression of flowering in plants is a hot topic, not only because that often the products of interest for human and animal nutrition are linked to the development of fruits or seeds, but also because the processes of gametes formation occurring in sexual organs are at the basis of recombination and genetic variability which constitutes the matter on which evolution acts, whether understood as natural or human driven. In the present study, we used an NGS approach to produce a grapevine flower transcriptome snapshot in different whorls and tissues including calyx, calyptra, filament, anther, stigma, ovary, and embryo in both pre- and post-anthesis phases. Our investigation aimed at identifying hub genes that unequivocally distinguish the different tissues providing insights into the molecular mechanisms that are at the basis of floral whorls and tissue development.

Transcriptomic analysis of temporal shifts in berry development between two grapevine cultivars of the Pinot family reveals potential genes controlling ripening time.

BMC Plant Biol 2021 Jul 7;21(1):327. Epub 2021 Jul 7.

Genetics and Genomics of Plants, Faculty of Biology & Center for Biotechnology, Bielefeld University, Bielefeld, Germany.

Background: Grapevine cultivars of the Pinot family represent clonally propagated mutants with major phenotypic and physiological differences, such as different colour or shifted ripening time, as well as changes in important viticultural traits. Specifically, the cultivars 'Pinot Noir' (PN) and 'Pinot Noir Precoce' (PNP, early ripening) flower at the same time, but vary in the beginning of berry ripening (veraison) and, consequently, harvest time. In addition to genotype, seasonal climatic conditions (i. Read More

Variable Populations of Grapevine Virus T Are Present in Vineyards of Hungary.

Viruses 2021 06 10;13(6). Epub 2021 Jun 10.

Institute of Plant Protection, Hungarian University of Agriculture and Life Sciences, Ménesi Road 44, H-1118 Budapest, Hungary.

Grapevine virus T (GVT) is a recently described foveavirus, which was identified from a transcriptome of a Teroldego grapevine cultivar in 2017. Recently, we surveyed vineyards and rootstock plantations in Hungary using small RNA (sRNA) high-throughput sequencing (HTS), at a time when GVT had not yet been described. A re-analysis of our sRNA HTS datasets and a survey of grapevines by RT-PCR revealed the presence of GVT in most of the vineyards tested, while at rootstock fields its presence was very rare.

Transcriptional, hormonal, and metabolic changes in susceptible grape berries under powdery mildew infection.

J Exp Bot 2021 Jun 9. Epub 2021 Jun 9.

BioISI - Biosystems and Integrative Sciences Institute, Faculty of Sciences, University of Lisbon, Campo Grande, Lisboa, Portugal.

Vitis vinifera berries are extremely sensitive to infection by the biotrophic pathogen Erysiphe necator causing powdery mildew disease and deleterious effects on grape and wine quality. The combined analysis of the transcriptome and metabolome associated with this common fungal infection has not been previously carried out in any fruit. In order to identify the molecular, hormonal and metabolic mechanisms associated with infection, healthy and naturally infected Carignan berries were collected at two developmental stages: late green (EL33) and early véraison (EL35).

Secondary Metabolism and Defense Responses Are Differently Regulated in Two Grapevine Cultivars during Ripening.

Int J Mol Sci 2021 Mar 17;22(6). Epub 2021 Mar 17.

Institute for Sustainable Plant Protection, National Research Council (IPSP-CNR), Strada delle Cacce 73, 10135 Torino, Italy.

'Nebbiolo' is one of the most important wine grape cultivars used to produce prestigious high-quality wines known throughout the world, such as Barolo and Barbaresco. 'Nebbiolo' is a distinctive genotype characterized by medium/high vigor, long vegetative and ripening cycles, and limited berry skin color rich in 3'-hydroxylated anthocyanins. To investigate the molecular basis of these characteristics, 'Nebbiolo' berries collected at three different stages of ripening (berry pea size, véraison, and harvest) were compared with 'Barbera' berries, which are rich in 3',5'-hydroxylated anthocyanins, using transcriptomic and analytical approaches.

Biosynthesis of the Sex Pheromone Component (E,Z)-7,9-Dodecadienyl Acetate in the European Grapevine Moth, Lobesia botrana, Involving ∆11 Desaturation and an Elusive ∆7 Desaturase.

J Chem Ecol 2021 Mar 29;47(3):248-264. Epub 2021 Mar 29.

Department of Biology, Lund University, Sölvegatan 37, SE-223 62, Lund, Sweden.

The European grapevine moth, Lobesia botrana, uses (E,Z)-7,9-dodecadienyl acetate as its major sex pheromone component. Through in vivo labeling experiments we demonstrated that the doubly unsaturated pheromone component is produced by ∆11 desaturation of tetradecanoic acid, followed by chain shortening of (Z)-11-tetradecenoic acid to (Z)-9-dodecenoic acid, and subsequently introduction of the second double bond by an unknown ∆7 desaturase, before final reduction and acetylation. By sequencing and analyzing the transcriptome of female pheromone glands of L. Read More

Overexpression of VlPRX21 and VlPRX35 genes in Arabidopsis plants leads to bioconversion of trans-resveratrol to δ-viniferin.

Plant Physiol Biochem 2021 May 12;162:556-563. Epub 2021 Mar 12.

Biological Resource Center, Korea Research Institute of Bioscience and Biotechnology (KRIBB), Jeongeup, 56212, Republic of Korea. Electronic address:

Stilbenes, including resveratrol and viniferins, a small family of polyphenols, are considered the most important phytoalexin group in Vitis species. In a previous study, we found that co-treatment of methyl jasmonate (MJ) and stevioside (STE) resulted in enhanced extracellular production of viniferins in grapevine cell suspension cultures. Thus, to further understand the mechanisms of viniferin production in grapevine cell cultures, we performed transcriptome analysis and isolated seven candidates of grapevine peroxidase genes (VlAPX6, VlGPX5, VlPRX13, VlPRX21, VlPRX35, VlPRX40, and VlPRX50).

VviNAC33 promotes organ de-greening and represses vegetative growth during the vegetative-to-mature phase transition in grapevine.

New Phytol 2021 07 16;231(2):726-746. Epub 2021 Mar 16.

Department of Biotechnology, University of Verona, Verona, 37134, Italy.

Plants undergo several developmental transitions during their life cycle. In grapevine, a perennial woody fruit crop, the transition from vegetative/green-to-mature/woody growth involves transcriptomic reprogramming orchestrated by a small group of genes encoding regulators, but the underlying molecular mechanisms are not fully understood. We investigated the function of the transcriptional regulator VviNAC33 by generating and characterizing transgenic overexpressing grapevine lines and a chimeric repressor, and by exploring its putative targets through a DNA affinity purification sequencing (DAP-seq) approach combined with transcriptomic data.

Molecular changes associated with response to powdery mildew (PM) caused by have been largely explored in cultivars, but little is known on transcriptional and metabolic modifications following application of resistance elicitors against this disease. In this study, the whole transcriptome sequencing, and hormone and metabolite analyses were combined to dissect long-term defense mechanisms induced by molecular reprogramming events in PM-infected 'Moscato' and 'Nebbiolo' leaves treated with three resistance inducers: acibenzolar-S-methyl, potassium phosphonate, and laminarin.
