Complete genome sequence of a novel member of the family Potyviridae isolated from Phellodendron amurense Rupr. in Liaoning, China

AbstractIn September 2017,Phellodendron amurense Rupr. plants showing yellow ringspots on leaves were observed in Liaoning, China. Flexuous filamentous particles (~1000 × 13 nm) were observed in the sap prepared from symptomatic leaves. A virus was detected in the symptomatic leaves by sequencing small RNAs and assembling the genome sequence. The complete genomic RNA was found to be 10,457 nucleotides in length excluding the poly(A) tail and to have the closest ph ylogenetic relationship to rose yellow mosaic virus (RoYMV), the sole member of newly established genusRoymovirus in the familyPotyviridae. The coat protein gene (CP) of this virus shares 49.2% nucleotide and 55.1% amino acid sequence identity with that of RoYMV. These results suggest that this virus, which was named “phellodendron yellow ringspot-associated virus” (PYRaV) is a new member of the genusRoymovirus.
