First report of Persimmon cryptic virus and Persimmon virus A in Korea.


In 2014, a total of 77 persimmon (Diospyros kaki) trees from Korean commercial orchards were surveyed for Persimmon cryptic virus (PeCV) and Persimmon virus A (PeVA). Leaf samples were collected from symptomatic trees with necrosis (two), or mosaic and leaf malformations (one) and 74 asymptomatic trees. Results of RT-polymerase chain reaction revealed 67 PeCV (87%) and 11 PeVA (14.3%) positive samples, including 9 samples with mixed infections of PeCV and PeVA. Mixed infections of both viruses were detected in one plant showing vein necrosis, and in 8 asymptomatic samples. This is thought to be the first report of PeCV and PeCV infection of persimmon in Korea.
