Genomic approaches were used to survey RNA viruses in the Phytophthora infestans collections from China. Total RNA was extracted from the mycelium of P. infestans and analysed using RT-PCR. The presence of P. infestans RNA virus 4 (PiRV 4) was detected in the studied isolates from Yunnan, China. This is thought to be the first report of an RNA virus in P. infestans in China.
