New reports of plum viruses and viroids in India
In India, a recent scientific article explored viral and viroid infections of plum (Prunus domestica) in Jammu & Kashmir state. Leaves of P. domestica showing mosaic and necrotic symptoms were collected from experimental field sites in Srinagar, Jammu & Kashmir in May 2022. Plum bark necrosis stem pitting-associated virus (Ampelovirus pruni, PBNSPaV), little cherry virus 1 (Velarivirus nanoavii, LChV1 - EU RNQP), American plum line pattern virus (Ilarvirus APLPV – EPPO A1 List), prunus necrotic ringspot virus (Ilarvirus PNRSV – EU RNQP), apple chlorotic leaf spot virus (Trichovirus mali, ACLSV – EU RNQP) and hop stunt viroid (Hostuviroid impedihumuli, HSVd – EU RNQP) were identified in leaf samples through high-throughput sequencing and validated by RT-PCR. This is the first report of PBNSPaV, LChV1, APLPV, PNRSV, ACLSV and HSVd in the state of Jammu & Kashmir and the first report of APLPV in India.
