Recombination is a common evolutionary tool for RNA viruses, and coronaviruses are no
exception. We review here the evidence for recombination in SARS-CoV-2 and reconcile …

Cucumber mosaic virus (CMV) is an important virus because of its agricultural impact in the
Mediterranean Basin and worldwide, and also as a model for understanding plant–virus …

Begomoviruses (Family Geminiviridae, Genus Begomovirus) have become the most
destructive group of plant viruses in tropical and subtropical regions of the world. The recent …

The combinatorial nature of genetic recombination can potentially provide organisms with
immediate access to many more positions in sequence space than can be reached by …

The severe economic consequences of emerging plant viruses highlights the importance of
studies of plant virus evolution. One question of particular relevance is the extent to which …

Horizontal gene transfer (HGT) is the stable transfer of genetic material from one organism to
another without reproduction or human intervention. Transfer occurs by the passage of …

RNA-RNA recombination is one of the strongest forces shaping the genomes of plant RNA
viruses. The detection of recombination is a challenging task that prompted the development …

Multipartite viruses have one of the most puzzling genetic organizations found in living
organisms. These viruses have several genome segments, each containing only a part of …

We examined the native plant host Solanum nigrum as reservoir of genetic diversity of
begomoviruses that cause the tomato yellow leaf curl disease (TYLCD) emerging in …

Begomoviruses (single-stranded DNA plant viruses) are responsible for serious agricultural
threats. Begomovirus populations exhibit a high degree of within-host genetic variation and …
