This study identified a novel virus in the family infecting Coll. et Hemsl, which is tentatively named polygonatum kingianum cryptic virus 1 (PKCV1). PKCV1 genome has two RNA segments: dsRNA1 (1926 bp) has an open reading frame (ORF) encoding an RNA-dependent RNA polymerase (RdRp) of 581 amino acids (aa), and dsRNA2 (1721 bp) has an ORF encoding a capsid protein (CP) of 495 aa. The RdRp of PKCV1 shares 20.70-82.50% aa identity with known partitiviruses, and the CP of PKCV1 shares 10.70-70.80% aa identity with known partitiviruses. Moreover, PKCV1 phylogenetically clustered with unclassified members of the family. Additionally, PKCV1 is common in planting regions and has a high infection rate in seeds.
