First report of Rhodococcus fascians causing leafy gall on Iberis sempervirens in Hungary

László Palkovics Zoltán Bozsó András Künstler János Ágoston Judit Kolozsváriné Nagy Ildikó Schwarczinger Dénes Dlauchy Lóránt Király József Fodor

Publication Name: Phytopathologia Mediterranea

Publication Date: 2024-01-01

Volume: 63

Issue: 3

Page Range: 465-473

Description:

In spring of 2023, leafy gall symptoms were detected on plants of evergreen candytuft (Iberis sempervirens ‘Pink Ice’) in Hungary. Bacteria isolated from gall-like tissues of short, stunted shoots, and showing a characteristic appearance on selective culture media were investigated using bacteriological and molecular methods, and phylogenetic analysis. Nucleotide sequences of the 16S rRNA gene, fasD and vicA genes were determined. Pathogenicity of selected isolates was confirmed on garden pea (Pisum sativum ‘Tristar’). Characterization of the investigated isolates indicated the presence of Rhodococcus fascians in I. sempervirens. This is the first report identifying the causal agent of leafy gall from this plant in Hungary.

Detection and molecular identification of 'Candidatus Phytoplasma asteris' associated with muscari virescence of three grape hyacinth species

János Ágoston Orsolya Viczián Emese Mergenthaler József Fodor

Publication Name: Plant Protection Science

Publication Date: 2023-01-01

Volume: 59

Issue: 4

Page Range: 389-393

Description:

Grape hyacinths are popular perennial, flowering bulbous plants. In 2018, 2019, and 2020, some plants of three Muscari species showed symptoms similar to those associated with phytoplasma infection in commercial ornamental gardens in Hungary. Symptoms included virescence of flowers and yellowing of leaves. Symptomatic and asymptomatic Muscari plants were sampled at two locations to detect and identify the pathogens involved. Total DNA was extracted from the plants and used as a template in polymerase chain reaction assays to amplify 16S rRNA gene sequences and housekeeping genes (tuf, secY) with phytoplasma-specific primers. The resulting PCR products from symptomatic plants were cloned and sequenced bidirectionally. Homology searching of the obtained sequences against the GenBank database indicated the presence of 'Candidatus Phytoplasma asteris' in the three Muscari species. This is the first report worldwide of C. P. asteris phytoplasma infecting M. botryoides and M. comosum, and its first identification in M. armeniacum in Hungary.
