First report of Asian prunus virus 2 and Cherry virus a infecting Japanese apricot (Prunus mume) in Korea.
To detect and identify viruses and viroids infecting Japanese apricot (Prunus mume) in Korea Republic, leaf samples from 2 cultivars, Takada and Wallyoung, grown in an orchard in September 2015, were harvested. Both plants did not display any observable disease symptoms. Five leaves from a single plant for each cultivar were used for total RNA extraction. Two libraries were generated and paired-end sequenced. The presence of Asian prunus virus 2 (APV2) and Cherry virus A (CVA) was detected based on various molecular analyses. This is thought to be the first report of APV2 and CVA infecting Japanese apricot in Korea Republic as well as the first report of CVA in the country.
