Abstract
In 2021, Plumbago indica plants with necrotic spots on their leaves were observed in Beijing, China. Through high-throughput sequencing, we discovered a putative novel member of the genus Cytorhabdovirus, which was provisionally named "plumbago necrotic spot-associated virus" (PNSaV). The full-length negative-sense single-stranded RNA genome of this virus is 13,180 nucleotides in length and contains eight putative open reading frames (ORFs), in the order 3′ leader-N-(P′)-P-P3-M-G-P6-L-5′ trailer. Phylogenetic analysis and pairwise comparisons suggested that PNSaV is most closely related to pastinaca cytorhabdovirus 1, with 59.2% nucleotide sequence identity in the complete genome and 56.4% amino acid sequence identity in the L protein. These findings suggest that PNSaV should be considered a new member of the genus Cytorhabdovirus.
