The species problem in plant virology.

Area of Science:

• Virology
• Taxonomy
• Bioinformatics

Background:

• Existing virus classification systems, including the family-genus-species model, are widely implemented.
• The virus group-virus system is currently utilized for plant viruses.

Purpose of the Study:

• To evaluate the efficacy and theoretical underpinnings of current viral classification and nomenclature systems.
• To propose improvements for a more standardized and accessible viral naming convention.

Main Methods:

• Comparative analysis of existing viral classification systems.
• Assessment of theoretical basis and ease of use for different nomenclature models.
• Evaluation of binomial nomenclature potential for plant viruses.

Main Results:

• The family-genus-species system is common but presents limitations.
• The virus group-virus system demonstrates a stronger theoretical foundation and greater usability for plant viruses.
• The potential for binomial nomenclature using vernacular and group names for plant viruses is identified.

Conclusions:

• The virus group-virus system offers significant advantages over the family-genus-species system for plant virus classification.
• Universal adoption of the virus group-virus system should be seriously considered.
• A binomial nomenclature based on English vernacular and group names could be developed for plant viruses.
