Abstract

A distinct double-stranded RNA (dsRNA) cryptic virus, named spinach cryptic virus 1 (SpCV1), was identified from spinach transcriptome datasets. The SpCV1 genome has two dsRNA genome segments. The larger dsRNA1 has an open reading frame for a conserved RNA-dependent RNA polymerase (RdRp). The smaller dsRNA2 encodes a putative coat protein (CP). The sequence identity of SpCV1 RdRp and CP to the closest cryptic virus is 81% and 60%, respectively. Phylogenetic analysis indicates that SpCV1 is a novel member of the genus Alphapartitivirus (family Partitiviridae).
