Abstract
Rhodiola plants exhibiting symptoms typical of phytoplasma infection were observed at an experimental farm near Edmonton, Alberta, Canada, in 2007. Phytoplasma infection was confirmed with a polymerase chain reaction (PCR)-assay using 16S ribosomal RNA primers developed specifically for phytoplasmas; the primers could amplify a band from tissue samples derived from infected, but not from asymptomatic, plants. Comparison between the sequence of the PCR product and the 16S ribosomal RNA gene sequences of other phytoplasmas available in GenBank indicated that the phytoplasma identified in rhodiola is a member of the subgroup 16SrI-B (aster yellows subgroup B).
Zusammenfassung
Als Heilkräuter angebaute Rosenwurz-Pflanzen mit typischen Symptomen einer Phytoplasma-Infektion wurden im Jahr 2007 auf einem Versuchsgut bei Edmonton in der kanadischen Provinz Alberta beobachtet. Phytoplasmen konnten daraufhin mit Hilfe der Polymerase-Kettenreaktion (PCR) mit Phytoplasmenspezifischen 16S-rRNA-Primern nachgewiesen werden. Die Primer vervielfältigten eine RNA-Bande aus infiziertem Pflanzengewebe, nicht jedoch aus symptomlosen Pflanzen. Ein Sequenzvergleich des PCR-Produkts mit anderen bei GenBank hinterlegten 16S-rRNA-Sequenzen von Phytoplasmen deutet darauf hin, dass das Rosenwurz-Phytoplasma zur Untergruppe 16SrI-B (Asternvergilbungs-Phytoplasma Untergruppe B) gehört.
