| Abstract:
A high homology (> 99.8 %) was found between the sequence of a 865 bp DNA fragment of the 16S rRNA gene of peach phytoplasmas and that of phytoplasmas recovered from apple trees affected by apple proliferation (AP). Polymerase chain reaction (PCR) strategies to amplify the phytoplasma DNA, cloning and sequencing procedures are described. The data obtained suggest that the same PCR-based assay can detect peach reddening- and AP-phytoplasmas. | |
