Molecular evolution of Turnip mosaic virus: evidence of host adaptation, genetic recombination and geographical spread.
Kazusato Ohshima,Yuka Yamaguchi,Ryo Hirota,Tamaki Hamamoto,Kenta Tomimura,Zhongyang Tan,Teruo Sano,Fumio Azuhata,John A. Walsh,J. D. Fletcher,Jishuang Chen,Abed Gera,Adrian J. Gibbs +12 more
TL;DR: The simplest of several possible interpretations of the trees is that TuMV originated, like its brassica hosts, in Europe and spread to the other parts of the world, and that the BR pathotype has recently evolved in east Asia.
Journal ArticleDOI
Molecular Characterization of Sweet potato feathery mottle virus (SPFMV) Isolates from Easter Island, French Polynesia, New Zealand, and Southern Africa
TL;DR: In this article, the results of a phylogenetic analysis of the coat protein (CP) encoding sequences of the sweet potato feathery mottle virus (SPFMV) were presented.
Journal ArticleDOI
Phylodynamic evidence of the migration of turnip mosaic potyvirus from Europe to Australia and New Zealand

TL;DR: The Bayesian coalescent analyses showed that TuMV probably started to migrate from Europe to Australia and New Zealand more than 80 years ago, and that distinct populations arose as a result of evolutionary drivers such as recombination.
Journal ArticleDOI
A review of the plant virus, viroid, liberibacter and phytoplasma records for New Zealand.
S. Veerakone,J. Tang,L. I. Ward,Lia W. Liefting,Z. Perez-Egusquiza,B. S. M. Lebas,C. Delmiglio,J. D. Fletcher,P. L. Guy +8 more
TL;DR: A complete review of the records of plant virus, viroid, liberibacter and phytoplasma in New Zealand has found evidence for 220 viruses, seven viroids, two liberibacters and two phy toplasmas.
Journal ArticleDOI
Investigating the Pea Virome in Germany-Old Friends and New Players in the Field(s).
Yahya Z. A. Gaafar,Kerstin Herz,Jonas Hartrick,J. D. Fletcher,Arnaud G. Blouin,Arnaud G. Blouin,Robin M. MacDiarmid,Robin M. MacDiarmid,Heiko Ziebell +8 more
TL;DR: A high virodiversity in the German pea fields that poses new challenges to diagnosticians, researchers, risk assessors and policy makers is revealed, as the impact of the new findings are currently unknown.
