Revision of taxonomic criteria for species demarcation in the geminiviridae family and new updated list of geminivirus species. Archives Of Virology 148:405-421.

Interpretive Summary: The Geminiviridae Study Group of the International Committee On the Taxonomy of Virus documents recent changes in criteria used to differentiate geminivirus species. An extensive list of currently recognized geminivirus species is presented. Changes in virus species status and official names are tabulated and cross-listed with synonyms and GenBank Accession numbers for sequenced DNA components of each geminivirus species.

Technical Abstract: Members of the family Geminiviridae have small circular single-stranded DNA genomes packaged within twinned particles. The Geminiviridae Study group of the International Committee On the Taxonomy of Viruses has revised criteria to be used in demarcating geminivirus species. Criteria to be used as a guideline to establish taxonomic status within a genus will include the number of genome components, organization of the genome, DNA A nucleotide sequence identity, the ability to trans-replicate genomic components, production of viable pseudo-recombinants, coat protein characteristics, and to a lesser degree natural host range and symptom phenotype. A current listing of geminivirus species is compiled to indicate changes in taxonomic status and nomenclature since the last ICTV Report.
