Characterization of plum pox virus infecting plum trees in North Transylvania and North Moldova of Romania

Prunus domestica represents one of the major fruit-trees exploited in the central European countries. Through our observations and investigations in northern Romania around the Carpatin region, notably the Bistrita-Nasaud valley, Cluj and Suceava, plums showing visible symptoms of plum pox virus (PPV) are commonly infected with the two major serogroups of PPV. D and M strains are commonly found in these areas. Refering to these observations, any serogroup of PPV can infect plums without restriction in this part of central Europe.
