Six novel begomoviruses infecting tomato and associated weeds in Southeastern B...
Castillo-Urquiza, Gloria P.; Beserra Jr., José Evando A.; Bruckner, Fernanda P.; Lima, Alison T. M.; Varsani, Arvind; Alfenas-Zerbini, PolianeThe incidence of tomato-infecting begomoviruses has sharply increased in Brazil following the introduction of the B biotype of the whitefly vector in the early 1990s. Five definitive species and six tentative species have been described since then. Here, we report the detection of members of an additional six novel species, three in tomato and three infecting weeds that are commonly associated with tomato field...
Changes to taxonomy and the International code of virus classification and nome...
Zerbini, Francisco Murilo; Adams, Michael J.; Lefkowitz, Elliot J.; King, Andrew M. Q.; Harrach, Balázs; Harrison, Robert L.; Knowles, Nick J.This article lists the changes to virus taxonomy approved and ratified by the International Committee on Taxonomy of Viruses (ICTV) in March 2017.
Establishment of three new genera in the family Geminiviridae: Becurtovirus, Er...
Zerbini, F. Murilo; Varsani, Arvind; Navas-Castillo, Jesús; Moriones, Enrique; Hernández-Zepeda, Cecilia; Idris, Ali; Brown, Judith K.The family Geminiviridae includes plant-infecting circular single-stranded DNA viruses that have geminate particle morphology. Members of this family infect both monocotyledonous and dicotyledonous plants and have a nearly global distribution. With the advent of new molecular tools and low-cost sequencing, there has been a significant increase in the discovery of new geminiviruses in various cultivated and non-...

Q.; Harrach, Balázs; Harrison, Robert L.; Knowles, Nick J.This article lists the changes to virus taxonomy approved and ratified by the International Committee on Taxonomy of Viruses (ICTV) in April 2016.Changes to virus taxonomy (the Universal Scheme of Virus Classification of the International Committee on Taxonomy of Viruses [ICTV]) now take place annually and are the result of a multi-stage process.

Capulavirus and Grablovirus: two new genera in the family Geminiviridae
Murilo Zerbini, F.; Varsani, Arvind; Roumagnac, Philippe; Fuchs, Marc; Navas-Castillo, Jesús; Moriones, Enrique; Idris, Ali; Briddon, Rob W.Geminiviruses are plant-infecting single-stranded DNA viruses that occur in most parts of the world. Currently, there are seven genera within the family Geminiviridae (Becurtovirus, Begomovirus, Curtovirus, Eragrovirus, Mastrevirus, Topocuvirus and Turncurtovirus). The rate of discovery of new geminiviruses has increased significantly over the last decade as a result of new molecular tools and approaches (rolli...
Revision of Begomovirus taxonomy based on pairwise sequence comparisons
Zerbini, F. Murilo; Brown, Judith K.; Navas-Castillo, Jesús; Moriones, Enrique; Ramos-Sobrinho, Roberto; Silva, José C. F.; Fiallo-Olivé, ElviraViruses of the genus Begomovirus (family Geminiviridae) are emergent pathogens of crops throughout the tropical and subtropical regions of the world. By virtue of having a small DNA genome that is easily cloned, and due to the recent innovations in cloning and low-cost sequencing, there has been a dramatic increase in the number of available begomovirus genome sequences. Even so, most of the available sequences...
A genome-wide pairwise-identity-based proposal for the classification of viruse...
Zerbini, F. Murilo; Muhire, Brejnev; Martin, Darren P.; Brown, Judith K.; Navas-Castillo, Jesús; Moriones, Enrique; Rivera-Bustamante, RafaelRecent advances in the ease with which the genomes of small circular single-stranded DNA viruses can be amplified, cloned, and sequenced have greatly accelerated the rate at which full genome sequences of mastreviruses (family Geminiviridae, genus Mastrevirus) are being deposited in public sequence databases. Although guidelines currently exist for species-level classification of newly determined, complete mast...
Revisiting the classification of curtoviruses based on genome-wide pairwise ide...
Zerbini, F. Murilo; Varsani, Arvind; Martin, Darren P.; Navas-Castillo, Jesús; Moriones, Enrique; Hernández-Zepeda, Cecilia; Idris, AliMembers of the genus Curtovirus (family Geminiviridae) are important pathogens of many wild and cultivated plant species. Until recently, relatively few full curtovirus genomes have been characterised. However, with the 19 full genome sequences now available in public databases, we revisit the proposed curtovirus species and strain classification criteria. Using pairwise identities coupled with phylogenetic evi...
