چکیده انگلیسی
A variety of techniques, such as typing with subgroup-specific monoclonal antibodies, restriction length polymorphism (RFLP) analysis or subgroup-specific RT-PCR are available for the discrimination of Plum pox virus (PPV) isolates. However, the existence of PPV isolates showing abnormal typing properties has been observed in the past [Candresse, T., Cambra, M., Dallot, S., Lanneau, M., Asensio, M., Gorris, M.T., Revers, F., Macquaire, G., Olmos, A., Boscia, D., Quiot J.B., Dunez, J., 1998. Comparison of monoclonal antibodies and polymerase chain reaction assays for the typing of isolates belonging to the D and M serotypes of Plum pox potyvirus. Phytopathology 88, 198-204.]. In an effort to understand the molecular mechanisms underlying such anomalous serological and molecular typing characteristics, partial 3â² (1449 nt) and 5â² (3706 nt) sequences have been determined for an atypical Turkish PPV isolate (Abricotier Turquie or Ab-Tk). The results obtained indicate that its unusual typing behaviour is caused by point mutations affecting key restriction sites and epitopes and confirm that this isolate represents a divergent member of the PPV-M subgroup. In addition, analysis of the partial Ab-Tk genomic sequences demonstrated that the 5â² region of the genome of this isolate has a mosaic structure resulting from recombination event(s), shedding new light on the evolutionary history of Plum pox virus.
