Abstract The climate crisis is changing temperature regimes worldwide, threatening global viticulture and wine production, as a primary driver of grape development. In Atlantic Canada, temperatures are projected to increase, inducing premature ripening, which can impact their biochemical profiles and, consequently, the quality vines wines produced. Temperature also key factor in determining composition structure resident fungal communities on leaves (phyllosphere) fruits (carposphere) vines. Therefore, better understand how these might change under potential future regimes, we experimentally manipulated grapevines ( Vitis sp. cv. L’Acadie blanc) field. We used on-the-row mini-greenhouses increase at different developmental, or phenological, stages fruits, across whole season. Phyllosphere carposphere were sampled four developmental stages, DNA was extracted, identified via ITS metabarcoding. found that phyllosphere had significantly community composition, remained relatively stable throughout plant Increased treatments most significant effect communities; observed samples exposed higher before onset ripening maintained more diverse Our analysis showed diversity among phyllopshere corresponds enrichments phytopathogenic taxa. However, this not conserved other growth when developed for results study will contribute understanding grapevine assembly. This allow producers adapt variability role could play health.

Microbial communities associated with the grapevine phyllosphere and carposhere are a fundamental determinant of grape wine quality. High throughput amplicon sequencing was used to profile fungal bacterial on phylloplane carposphere Vitis vinifera L. cv's Chardonnay Pinot noir in Elgin Hemel-en-Aarde districts South Africa 2021-2022 growing season. The subsequent must analysed determine prevalent microbiome. most abundant genera found both were Pseudomonas Filobasidium. LEfSe (Linear discriminant analysis Effect Size) revealed significant differences biomarkers from leaf, berry samples; however, no identified for cultivar nor location. Fungal β-diversity significantly similar at different phenological stages, whereas regardless site colonisation. However, skin integrity grapes may have influenced microbial diversity.

Abstract Background Plant and soil microbiomes can interfere with pathogen life cycles, but their influence on disease epidemiology remains understudied. Here, we analyzed the relationships between plant long-term epidemiological records of grapevine downy mildew, a major caused by oomycete Plasmopara viticola . Results We found that certain microbial taxa were consistently more abundant in plots lower incidence severity community composition could predict severity. Microbial diversity was not strongly linked to records, suggesting is related abundance specific taxa. These key identified topsoil, where pathogen’s oospores overwinter, phyllosphere, zoospores infect leaves. By contrast, leaf endosphere, mycelium develops, contained few interest. Surprisingly, microbiota better predictor than microbiota, microbiome be indicator dynamics this primarily aerial disease. Conclusion Our study integrates data profiles healthy plants reveal fungi bacteria relevant for biocontrol mildew. The resulting database provides valuable resource designing consortia potential activity. framework applied other crop systems guide development strategies reduce pesticide use agriculture.
