Near-complete genome sequences of marna- and nora-like picornaviruses from small pond water in Japan

Key Points

• The research aims to identify and analyze the genome sequences of marna- and nora-like viruses from small pond water in Japan.
• Conducted metatranscriptomic analysis of freshwater pond samples in Japan.
• Performed phylogenetic analyses to assess the evolutionary relationships of the identified viruses.
• Identified near-complete genome sequences of a marna-like virus and a nora-like virus.
• Both viruses form deep, isolated lineages within the order Picornavirales, indicating potential new evolutionary groups.
