Insight into the microbial world of Bemisia tabaci cryptic species complex and ...
Wang, Hua-Ling; Lei, Teng; Xia, Wen-Qiang; Cameron, Stephen L.; Liu, Yin-Quan; Zhang, Zhen; Gowda, Maruthi M. N.; Navas-Castillo, JesúsMade available in DSpace on 2019-10-06T15:41:33Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-12-01; China Postdoctoral Science Foundation; Bill and Melinda Gates Foundation; The 37 currently recognized Bemisia tabaci cryptic species are economically important species and contain both primary and secondary endosymbionts, but their diversity has never been mapped systematically across the group.

Evidence for a complex of emergent poleroviruses affecting pepper worldwide
Fiallo-Olivé, Elvira; Navas-Hermosilla, Elisa; Ferro, Camila G.; Zerbini, F. Murilo; Navas-Castillo, JesúsIn recent years, symptoms of vein yellowing and leaf roll in pepper crops associated with the presence of poleroviruses (genus Polerovirus, family Luteoviridae) have been emerging in many countries worldwide. Spain was the first country in Europe where the yellowing disease of pepper was observed. In this work, a polerovirus isolate from Spain that infects pepper and has been shown to be transmitted by the aphi...
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-...
Complete nucleotide sequences of two new begomoviruses infecting the wild malva...
Fiallo-Olivé, Elvira; Zerbini, F. Murilo; Navas-Castillo, JesúsWild malvaceous plants are hosts for a large number of begomoviruses (genus Begomovirus, family Geminiviridae) in both the Old World and the New World. Here, we report the complete genome sequences of two new begomoviruses from Melochia sp. plants from Brazil. The cloned bipartite genomes, composed of DNA-A and DNA-B, showed the typical organization of the New World begomoviruses but they were distantly related...
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...
Alphasatellitidae: a new family with two subfamilies for the classification of ...
Murilo Zerbini, F.; Briddon, Rob W.; Martin, Darren P.; Roumagnac, Philippe; Navas-Castillo, Jesús; Fiallo-Olivé, Elvira; Moriones, EnriqueNanoviruses and geminiviruses are circular, single stranded DNA viruses that infect many plant species around the world. Nanoviruses and certain geminiviruses that belong to the Begomovirus and Mastrevirus genera are associated with additional circular, single stranded DNA molecules (~ 1-1.4 kb) that encode a replication-associated protein (Rep). These Rep-encoding satellite molecules are commonly referred to a...
