Harnessing benzamides as plant stress inhibitors, growth promoters and in management of crop resilience—A review

Plant Biology, EarlyView.
Benzamides boost crop resilience by inhibiting poly(ADP‐ribose) polymerase (PARP) to enhance stress tolerance and, through their antimicrobial, herbicidal, and insecticidal derivatives, they offer broad protection for sustainable crop improvement. Abstract Benzamides have emerged as potent stress inhibitors and growth promoters in plant biotechnology ...

Response of hybrid grapes (Vitis spp.) to two biotic stress factors and their seedlessness status

Open Life Sciences
Grape varieties belonging to the Vitis vinifera species are widely grown worldwide, and many of these are susceptible to powdery mildew and downy mildew. However, wild Vitis species are pretty resistant to these diseases.

Efficacy of using grape cane extracts against Plasmopara viticola under field conditions and their impact on the composition of berries and musts of Vitis vinifera L. cv. Riesling

OENO One
Grapevine downy mildew caused by Plasmopara viticola is a deleterious vine disease currently controlled using synthetic and copper-based fungicides. Environmental concerns surrounding such fungicides necessitate sustainable alternatives like grape cane ...

Marker-assisted pyramiding of resistance loci to grape downy mildew [PDF]

Pesquisa Agropecuária Brasileira, 2018
Abstract: The objective of this work was to use a marker-assisted selection for pyramiding the resistance loci Rpv1 and Rpv3.1 in grapevine (Vitis vinifera), and to evaluate their conferred resistance against Brazilian downy mildew (Plasmopara viticola) isolates. A progeny of 23 plants, segregating for the two resistance loci, was obtained by the cross

Biotransformation of monoterpenols upon pre‐treatment with oregano essential oil vapour alleviates downy mildew susceptibility in grapevine leaves

Plant Biology, EarlyView.
Pre‐treatment of grapevine plants with oregano essential oil vapour alleviates downy mildew susceptibility by accumulation of monoterpenol glycosides. Abstract Grapevine downy mildew, caused by the oomycete Plasmopara viticola, is a destructive disease that causes major economic losses as most elite grapevine cultivars are susceptible to this pathogen.

A Novel Grape Downy Mildew Resistance Locus from Vitis rupestris [PDF]

, 2019
This study represents the QTL mapping efforts for downy mildew resistance in grapevine using a wild V. rupestris x V. riparia F1 mapping family. Genotyping by sequencing was used to generate genome wide SNP markers based on the APEK1 restriction sites in

Gene expression and metabolic variability in fungus‐resistant PIWI (‘Pilzwiderstandsfähig’) grape cultivars

Journal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 5841-5850, 15 August 2026.
Abstract BACKGROUND Fungus‐resistant PIWI (Pilzwiderstandsfähig) grape cultivars are promising for reducing pesticide inputs in viticulture, but their enological potential is still poorly characterized. We performed a pilot, single‐vintage study integrating berry gene expression and phenolic composition in five Italian red PIWI cultivars (Cabernet ...

Vineyard evaluation of stilbenoid‐rich grape cane extracts against downy mildew: a large‐scale study [PDF]

, 2019
International audiencePlasmopara viticola control in organic viticulture requires copper-based fungicides with harmful effects on health and the environment. Plant extracts represent a biorational eco-friendly alternative to copper. The aim of this study

Antimicrobial properties of tannin extracts against the phytopathogenic oomycete Plasmopara viticola

OENO One
Downy mildew (Plasmopara viticola) is one of the most devastating diseases for European grapevines (Vitis vinifera L.), requiring extensive use of copper-based or synthetic pesticides.
