Plum pox virus strain W found in Kazakhstan

In Kazakhstan, a survey on plum pox virus (Potyvirus, PPV – EPPO A2 List) was conducted in July 2014 in the region of Almaty, in stone-fruit collection orchards (Prunus domestica and P. armeniaca), in nurseries and in private gardens. Leaf samples (75) were collected from symptomatic and asymptomatic trees in 5 areas, and then tested by RT-PCR. Out of the 75 collected samples, 24 were infected by PPV-D and 1 sample was found to be infected by PPV-W. This sample had been collected from a plum (P. domestica) tree growing in a private garden and showing strong chlorotic ring patterns on the leaves. This is the first time that PPV-W is reported from Kazakhstan. So far, this strain had only been reported from Canada (a single record), Latvia, Russia and the Ukraine.
