The partial genome of Bacillus phage SIOphi, the exemplar isolate of Siophivirus SIOphi, the only species in the genus, is 146 698 bp with 206 unique predicted protein coding sequences.
Betabotuliviruses have a mono-segmented genome and infect fungi. Some members of the genus have been identified in association with grapevine leaves infected with the oomycete Plasmopara viticola. Betabotuliviruses are phylogenetically distinct from other botourmiaviruses.
No true virions are associated with betabotouliviruses since their genomes have no capsid protein gene.
Epsilonsclerouliviruses have a mono-segmented genome. Members of the genus have been identified in association with grapevine leaves affected by infection with the oomycete Plasmopara viticola, and are phylogenetically distinct from other botourmiaviruses.
No true virions are associated with epsilonsclerouliviruses since their genomes have no capsid protein gene.
