Rediscovery of Seven Long-Forgotten Species of Peronospora and Plasmopara (Oomycota)

Mycobiology, 2020
The family Peronosporaceae, an obligate biotrophic group of Oomycota, causes downy mildew disease on many cultivated and ornamental plants such as beet, cucumber, grape, onion, rose, spinach, and sunflower. To investigate the diversity of Peronosporaceae

The influence of downy mildew tolerance of grape varieties on the biosynthesis of stilbenes in callus as potential sources of bioactive substances*

BIO Web of Conferences, 2020
Stilbenes represent a considerable practical interest in relation to their benifits to the human health. Callus culture of the grape, which is a natural producer of stilbenes, can serve as an effective source of these compounds.

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 ...

Variability and Heritability of Several Important Traits for Grape Production and Breeding

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2008
Yield capacity, quality of grapes and resistance to downy mildew attack remain the important breeding objectives for grape. For these traits were analyzed more than 2200 F1 hybrids, belonging to eight combinations of wine grape.

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.

Field and In vitro Study of Pronos and Dormulin against Downy Mildew and Powdery Mildew Diseases of Grape

Asian Journal of Environment & Ecology, 2023
Downy mildew and powdery mildew are destructive diseases of grapes which require application of fungicides. Fungicides are expensive and cause ecological contamination and resistance. Pronos and Dormulin are 'Multi nutrient fertilizers' which were evaluated against the diseases.

Transcriptional Profiling of Resistant and Susceptible Cultivars of Grapevine (Vitis L.) Reveals Hypersensitive Responses to Plasmopara viticola

Frontiers in Microbiology, 2022
Grapevine downy mildew is the most serious disease of grapevine cultivars that affects the rate of resistance/susceptibility to Plasmopara viticola. In this study, we used the susceptible cultivar “Zitian Seedless” and the resistant cultivar “Kober 5BB ...

Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1649-1661, September 2026.
The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

Pest Management Science, Volume 82, Issue 9, Page 8159-8170, September 2026.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...
