Taxonomy and relationships

monogeminivirus: Geminiviridae

Virus(es) with serologically unrelated virions

Maize streak, chloris striate mosaic, African cassava mosaic and tobacco leaf curl viruses.

Additional comments on relationships

The genome of the virus has clear sequence homology with the genomes of maize streak and wheat dwarf viruses.
