Detection and identification of three `Candidatus phytoplasma' species in Picea spp. trees in Poland
Journal of Phytopathology 159 (11-12), 796-798
Abstract: We report the detection of phytoplasmas in Picea abies, Picea glauca and Picea pungens trees with witches' brooms and other growth abnormalities and also in symptomless trees. Phytoplasmas were detected in c. 25% of the tested plants by polymerase chain reaction using phytoplasma universal P1/P7 followed by R16F2n/R16R2 primer pairs. The phytoplasmas were classified as members of the phylogenetic groups: 16SrI, `Ca. Phytoplasma asteris'; 16SrIII, X-disease phytoplasma group; and 16SrXXI, `Ca. Phytoplasma pini'.
