The water status of fruit and nut crops is critical to the high productivity, quality value these crops. Water often estimated managed with indirect measurements soil moisture models evapotranspiration. However, cultivated trees vines have characteristics associated cultural practices that complicate such methods, particularly variable discontinuous canopies, extensive but low-density, root systems relatively hydraulic resistance. Direct continuous measurement plant desirable in as integrates its unique combination weather, factors. To measure potential temporal sampling rates, a stem-embedded microchip microtensiometer sensor has been developed tested several for long-term monitoring stem potential. Results on orchards vineyards good excellent, very correlations pressure chamber standard method. primary challenge establishing maintaining intimate contact xylem long periods time, anatomies, growth wound reactions. Sources variability utilization data stream, relation irrigation scheduling, are discussed. field possible provide opportunities both research farming.

Secondary metabolites in grapevine: crosstalk of transcriptional, metabolic and hormonal signals controlling stress defence responses in berries and vegetative organs

Frontiers in Plant Science, Год журнала: 2023, Номер 14

Опубликована: Июнь 19, 2023

Abiotic stresses, such as temperature, heat waves, water limitation, solar radiation and the increase in atmospheric CO 2 concentration, significantly influence accumulation of secondary metabolites grapevine berries at different developmental stages, vegetative organs. Transcriptional reprogramming, miRNAs, epigenetic marks hormonal crosstalk regulate metabolism berries, mainly phenylpropanoids volatile organic compounds (VOCs). Currently, biological mechanisms that control plastic response cultivars to environmental stress or occur during berry ripening have been extensively studied many worlds viticultural areas, vines grown under various agronomic managements. A novel frontier study these is involvement miRNAs whose target transcripts encode enzymes flavonoid biosynthetic pathway. Some miRNA-mediated regulatory cascades, post-transcriptionally key MYB transcription factors, showing, for example, a role influencing anthocyanin UV-B light ripening. DNA methylation profiles partially affect transcriptome plasticity cultivars, contributing modulation qualitative traits. Numerous hormones (such abscisic jasmomic acids, strigolactones, gibberellins, auxins, cytokynins ethylene) are involved triggering vine abiotic biotic factors. Through specific signaling mediate antioxidants contribute quality intervene defense processes, highlighting stressors can be similar The expression genes responsible hormone biosynthesis largely modulated by conditions, thus resulting numeourous interactions between surrounding environment.

Enhancing grapevine breeding efficiency through genomic prediction and selection index

G3 Genes Genomes Genetics, Год журнала: 2024, Номер 14(4)

Опубликована: Фев. 24, 2024

Grapevine (Vitis vinifera) breeding reaches a critical point. New cultivars are released every year with resistance to powdery and downy mildews. However, the traditional process remains time-consuming, taking 20-25 years, demands evaluation of new traits enhance grapevine adaptation climate change. Until now, selection has relied on phenotypic data limited number molecular markers for simple genetic such as pathogens, without clearly defined ideotype, was carried out large scale. To accelerate address these challenges, we investigated use genomic prediction, methodology using predict genotypic values. In our study, focused 2 existing programs: Rosé wine Cognac production. programs, several families were created through crosses emblematic interspecific resistant varieties Thirty evaluated each program, prediction methods: Genomic Best Linear Unbiased Predictor Least Absolute Shrinkage Selection Operator. The results revealed substantial variability in predictive abilities across traits, ranging from 0 0.9. These discrepancies could be attributed factors trait heritability characteristics. Moreover, explored potential across-population by leveraging other populations training sets. Integrating allowed us identify superior individuals multivariate index method. ideotype program collaboratively representatives wine-growing sector.

Stimulation of secondary metabolism in grape berry exocarps by a nature-based strategy of foliar application of polyols

OENO One, Год журнала: 2024, Номер 58(1)

Опубликована: Март 25, 2024

In grapes under drought stress, polyols accumulate through tight coordination at the molecular level between increased membrane transport of and inhibition polyol oxidation. Here, effects on grape metabolism an exogenous foliar application as a potential sustainable viticultural practice to increase grapevine performance berry quality were thoroughly assessed. Grapevines pulverised with solution containing 2 mM mannitol sorbitol, metabolome exocarps important metabolic pathways associated analysed véraison mature stages. By combining metabolomics analysis using UPLC-MS, enzyme activity assays targeted transcriptional analyses, it was demonstrated that stimulated by 3.5-fold 6-fold abscisic acid (ABA) biosynthesis berries, respectively. It also concentration anthocyanins, stilbenes total phenolics in upregulation phenylpropanoid, stilbenoid anthocyanin biosynthetic shown increases phenylalanine-ammonia lyase (PAL) (3-fold) VviPAL1 expression, stilbene synthase 1 (VviSTS1) transcripts (ca. 5-fold), UDP-glucose:flavonoid 3-O-glucosyltransferase (UFGT) VviUFGT1 among other results, stage, when these changes most noticeable. Many secondary metabolites synthesised identified UPLC-MS present higher quantities from polyol-treated plants such fertaric acid, E-resveratrol, E-piceatannol, piceid, pallidol, E-ε-viniferin, myricetin-hexoside 1, cyanidin-3-O-glucoside malvidin-3-O-(6-p-coumaroyl)-glucoside. Foliar low-concentration is, therefore, promising biostimulant-based strategy improve nutritional value current context climate change.

Modifications of Grapevine Berry Composition Induced by Main Viral and Fungal Pathogens in a Climate Change Scenario

Frontiers in Plant Science, Год журнала: 2021, Номер 12

Опубликована: Дек. 8, 2021

The grapevine is subject to high number of fungal and viral diseases, which are responsible for important economic losses in the global wine sector every year. These pathogens deteriorate berry quality either directly via modulation fruit metabolic pathways production endogenous compounds associated with bad taste and/or flavor, or indirectly their impact on vine physiology. most common devastating diseases viticulture gray mold, downy mildew (DM), powdery (PM), caused, respectively by Botrytis cinerea , Plasmopara viticola Erysiphe necator . Whereas B. mainly infects deteriorates ripening directly, deteriorations DM PM mostly indirect a reduction photosynthetic leaf area. Nevertheless, mildews can also infect berries at certain developmental stages alter biosynthesis unpleasant flavor that impair ultimate quality. furthermore host wide range viruses reduce longevity, productivity different ways. widespread virus-related known nowadays, Grapevine Leafroll Disease (GLRD), Fanleaf (GFLD), more recently characterized red blotch disease (GRBD). Future climatic conditions creating favorable environment proliferation virus-insect vectors, so spread expected increase wine-growing regions. However, climate change evolution pressure will be variable depending region pathogen, remaining certainly major phytosanitary threat regions because development rate large extent temperature-driven. This paper aims provide review published literature grape physiology Our overview highlights gaps our understanding plant-pathogen interactions, valuable conceiving future research programs dealing impacts metabolism.
