(Public Library of Science (PLoS), 2018)
The stolbur phytoplasma vector Hyalesthes obsoletus is generally considered as a polyphagous species associated with numerous wild and cultivated plants. However, recent research in southeastern Europe, the distribution ...
Experimental and molecular evidence of Reptalus panzeri as a natural vector of bois noir
(Wiley-Blackwell, Hoboken, 2014)
Bois noir (BN) is an economically important grapevine yellows disease induced by the stolbur phytoplasma and principally vectored by the cixiid Hyalesthes obsoletus. This study addresses the involvement of other planthoppers ...
Multigene sequence data and genetic diversity among 'Candidatus Phytoplasma ulmi' strains infecting Ulmus spp. in Serbia
(Wiley-Blackwell, Malden, 2011)
Elm yellows phytoplasmas (EY) belonging to the 16SrV-A subgroup were recently proposed as a new candidate species 'Candidatus Phytoplasma ulmi'. These pathogens infect elm trees, causing leaf yellowing and premature drying. ...
