Binomial nomenclature for virus and viroid species (continued)
For many years, proposals to use binomial names to name virus species have been debated among the virology community. In 2021, the International Committee on Taxonomy of Viruses (ICTV) approved a uniform system of formal virus names which follows the binomial 'genus-species' format with or without Latinized species epithets. For example, the virus species which is causing rose rosette is now called Emaravirus rosae. This new rule is being implemented and new names are gradually being proposed by ICTV.
As a user of taxonomy, the EPPO Secretariat has started to implement these changes for virus names (mainly plant viruses) in the EPPO Global Database. In 2022, the first changes were made for a number of genera (EPPO RS 2022/207) and continued in 2023 and 2024 (RS 2023/177, RS 2024/031, RS 2024/125). In September 2024, ICTV released an updated list, and as a consequence, changes were made in the EPPO Global Database for the virus and viroid species belonging to families and genera listed below:
Family | Genus | EPPO Code | |
Viruses | Metaxyviridae | Cofodevirus | 1COFVG |
Solemoviridae | Enamovirus | 1ENAMG | |
Polerovirus | 1POLVG | ||
Sobemovirus | 1SOBEG | ||
Partitiviridae | Alphapartitivirus | 1ACRYG | |
Betapartitivirus | 1BCRYG | ||
Deltapartitivirus | 1DCRVG | ||
Gammapartitivirus | 1GCRYG | ||
Viroids | Avsunviroidae | Avsunviroid | 1AVSUG |
Elaviroid | 1ELAVG | ||
Pelamoviroid | 1PELAG | ||
Viroids | Pospiviroidae | Apscaviroid | 1APSCG |
Cocadviroid | 1CCADG | ||
Coleviroid | 1KOLEG | ||
Hostuviroid | 1HOSTG | ||
Pospiviroidae | 1POSPF |
