First report of maize redness disease in Hungary

Abstract During 2010, several maize production areas in Hungary were surveyed for the occurrence of maize redness (MR) disease symptoms associated with stolbur phytoplasma, as well as for the presence of the known vector of the disease, a planthopper Reptalus panzeri (Low). Incidence of maize plants with symptoms of reddening was low in all surveyed areas. Altogether, 25 symptomatic maize plants were collected at 9 localities and tested for phytoplasma presence. In addition, from one locality specimens of cixiids R. panzeri and Hyalesthes obsoletus Signoret were collected and PCR analyzed. Presence of stolbur phytoplasma in MR symptomatic maize plants and stolbur-infected R. panzeri was identified at the single locality Monorierdő in central Hungary. This finding represents the first report of MR presence in Hungary

Két magyarországi Candidatus Phytoplasma solani törzs de novo genom szekvenálása

A dolgozatban két hazai ‘Candidatus Phytoplasma solani’ törzs genomjának de novo vázlatos összeállítását, strukturális és funkcionális annotációját, valamint összehasonlító jellemzését végeztük el. A de novo összeállítást a SPAdes programmal végeztük. Ezek strukturális és funkcionális annotációjához a RAST programot használtuk. A két törzs genomja nagyfokú átfedést mutatott a kromoszómaméretben, a G+C tartalomban, az azonosított gének számában, és a funkciók tekintetében is

Survey and genetic diversity of phytoplasmas from the 16SrV-C and -D subgroups in Hungary

International audienceIn order to evaluate the risk represented by the wild reservoir as a possible source of 'flavescence doree' outbreaks in Hungary, diverse wild perennial plants growing in vineyard areas were tested for the presence of 16SrV-C and D subgroup phytoplasmas. 16SrV phytoplasmas were detected by nested PCR-RFLP on the 16SrDNA in alders (86% infected) and in clematis (71% infected). Further characterisation by sequencing of the map gene revealed in both plants strains having the same map gene sequence as 'flavescence doree' strains

Molecular detection of potato stolbur phytoplasma in Serbia

In August 2010 potato plants expressing symptoms of phytoplasma infection were collected from three localities in Vojvodina province of Serbia and analyzed for phytoplasma presence. Phytoplasma detection was performed by PCR/RFLP analyzes of 16S rRNA gene and by stolbur-specific PCR amplification with Stol11 primers. Stolbur phytoplasma was detected in all symptomatic potato plants analyzed. This is the first report of molecular detection of stolbur phytoplasma infecting potato in Serbia
