- Celavirus is a genus within the family Potyviridae, currently comprising a single recognized species, Celavirus apii.
- Eight novel celavirus-like viral genome contigs were identified from five distinct sources, likely representing four novel viral species.
- Phylogenetic analysis placed all novel viruses in a monophyletic clade with CeLV and SaPlV2, distinct from other genera in Potyviridae.
- Conserved functional domains typical of potyvirid polyproteins, including CI, NIa-Pro, and NIb, were identified, while others like P1, HC-Pro, and CP were not detected.
- The study expands the known diversity of Celavirus and offers new insights into its genome organization, host associations, and evolutionary position.
