Increase of plum resistance to natural infections with Plum pox virus

Plant Protection Science, 2002
The mechanical inoculation of the plum leaves of the trees in the nursery, in the first year of growth, has stimulated the activation of the plants' defensive system, fact that lead to their resistance to natural Plum pox virus (PPV) infections.

First Report of Plum Pox Virus on Plum in Uzbekistan

Plant Disease, 2020
Apricot, sweet cherry, plum, and peach are economically important stone fruit crops in Uzbekistan. Plum pox virus from the genus Potyvirus in the family Potyviridae is the causal agent of sharka disease. Plum pox virus (PPV) is the most destructive viral pathogen of stone fruit trees. No information is available on PPV occurrence in Uzbekistan. In 2019,

The global phylogeny of Plum pox virus is emerging

Journal of General Virology, 2019
The 206 complete genomic sequences ofPlum pox virusin GenBank (January 2019) were downloaded. Their main open reading frames (ORF)s were compared by phylogenetic and population genetic methods. All fell into the nine previously recognized strain clusters; the PPV-Rec and PPV-T strain ORFs were all recombinants, whereas most of those in the PPV-C, PPV ...

Coniferyl aldehyde from the phenylpropanoid pathway targets pyruvate kinase in Dactylobotrys graminicola to confer sheath rot resistance in hulless barley

Journal of Integrative Plant Biology, EarlyView.
Hulless barley resists the newly identified sheath rot disease caused by the necrotrophic fungal pathogen Dactylobotrys graminicola by releasing coniferyl aldehyde, a natural compound that disrupts energy production in the fungus. ABSTRACT Dactylobotrys graminicola (Dgr), a necrotrophic fungal pathogen, has recently been identified as the causative ...
