First report of Plum pox virus in Uzbekistan
In Uzbekistan, plum (Prunus domestica cv. Ispanskiy) trees showing foliar symptoms (pale green rings and spots) were observed in 2019, in a 21-year-old orchard located in the Tashkent region. Samples were collected from 4 trees (1 symptomatic leaf per tree) located at the 4 corners of the orchard, and tested by DAS-ELISA and RT-PCR. Plum pox virus (Potyvirus, PPV – EPPO A2 List) was detected in all samples. All four isolates were identified as PPV-D. No positive reaction was observed with primers specific to the PPV strains M, W and C. This is the first time that plum pox virus is reported from Uzbekistan. It is concluded that further studies are needed to determine the prevalence, host range and genetic variability of PPV in Uzbekistan.
The situation of plum pox virus in Uzbekistan can be described as follows: Present, only in some areas (detected in 2019 in 1 plum orchard, Tashkent region).
