The future of academic publishing
(Nature Research, 2023-07-13)Academic publishing is the backbone of science dissemination — but is the current system fit for purpose? We asked a diverse group of scientists to comment on the future of publishing. They discuss systemic issues, ... -
The Plant Negative-Sense RNA Virosphere: Virus Discovery Through New Eyes
(Frontiers Media, 2020-09-16)The use of high-throughput sequencing (HTS) for virus diagnostics, as well as the importance of this technology as a valuable tool for discovery of novel viruses has been extensively investigated. In this review, we consider ... -
Tomato apical leaf curl virus: a novel, monopartite geminivirus detected in tomatoes in Argentina
(2018-01)Plant viruses that are members of the Geminiviridae family have circular single-stranded DNA (ssDNA) genome and are responsible for major crop diseases worldwide. We have identified and characterized a novel monopartite ... -
Tomato mottle wrinkle virus, a recombinant begomovirus infecting tomato in Argentina
