Since 2005, foliar symptoms of a presumptive virus disease, including chlorotic and necrotic ring patterns or blotches, have been observed in peach (Prunus persica L.) trees in Aguascalientes, Mexico. Infected leaf samples were analysed based on general scanning for Potyvirus by dot blot and by RT-PCR for specific detection. The present study describes the identification of Plum pox virus (PPV) as the causal agent of the virus disease on peach orchards in Aguascalientes, Mexico. RFLP analyses showed that PPV Mexican strain belongs to genotype D, previously detected in North America (USA and Canada). To our knowledge, this is the first report of the presence of PPV in Mexico and this data can positively contribute to establish appropriate phytosanitary control measures, in Mexico as well worldwide.
