Judith K. Brown,F. Murilo Zerbini,Jesús Navas-Castillo,Enrique Moriones,Roberto Ramos-Sobrinho,José Cleydson F. Silva,Elvira Fiallo-Olivé,Rob W. Briddon,Cecilia Hernández-Zepeda,Ali M. Idris,V. G. Malathi,Darren P. Martin,Rafael F. Rivera-Bustamante,Shigenori Ueda,Arvind Varsani +14 more
TL;DR: Revised guidelines for the classification and nomenclature of begomoviruses are proposed and genome-wide pairwise identities of 91 % and 94 % are proposed as the demarcation threshold for begomviruses belonging to different species and strains, respectively.
Journal ArticleDOI

Sheila S. Tavares,Sheila S. Tavares,Roberto Ramos-Sobrinho,J. González-Aguilera,G. S. A. Lima,Iraildes Pereira Assunção,Francisco Murilo Zerbini +6 more
TL;DR: The aim of this study was to further characterize the diversity of begomoviruses infecting weeds in Brazil, and to propose new species, for which the following names are proposed: Sida yellow blotch virus (SiYBV), SIDA yellow net virus ( SiYNV), Sida mottle Alagoas virus
Journal ArticleDOI
Molecular and morpho-cultural characterization of Colletotrichum spp. associated with anthracnose on Capsicum spp. in northeastern Brazil

TL;DR: Five species within Colletotrichum that cause anthracnose in bell and hot pepper using phylogenetic and morphological criteria were identified and it was concluded that five species: C. brevisporum, C. scovillei,C.
Journal ArticleDOI
Characterization of the Complete Genome and P0 Protein for a Previously Unreported Genotype of Cotton Leafroll Dwarf Virus, an Introduced Polerovirus in the United States.
S. Avelar,Roberto Ramos-Sobrinho,Kassie Conner,Robert L. Nichols,Kathy S. Lawrence,Judith K. Brown +5 more
TL;DR: Pairwise nucleotide identity comparisons of ORF0 sequences for the three CLRDV-AL field isolates indicated that they were >99% identical, suggesting that this previously unknown CL RDV genotype represents a single introduction to Alabama.
Journal ArticleDOI
Genetic variability and population structure of the New World begomovirus Euphorbia yellow mosaic virus.
Talita Bernardon Mar,César A. D. Xavier,Alison T. M. Lima,Angélica Maria Nogueira,José Cleydson F. Silva,Roberto Ramos-Sobrinho,Douglas Lau,F. Murilo Zerbini +7 more
TL;DR: Assessment of the genetic variability and population structure of begomoviruses infecting E. heterophylla in samples collected throughout nine Brazilian states from 2009 to 2014 shows negative selection was predominant in all six subpopulations.
