The recurrent domestication of viruses: major evolutionary transitions in parasitic wasps.

摘要: Several lineages of endoparasitoid wasps, which develop inside the body other insects, have domesticated viruses, used as delivery tools essential virulence factors for successful development their progeny. Virus domestications are major evolutionary transitions in highly diverse parasitoid wasps. Much progress has recently been made to characterize nature these ancestrally captured endogenous viruses that evolved within wasp genomes. domestication from different viral families occurred at least three times This convergence led strategies. Polydnaviruses (PDVs) gene transfer agents and virus-like particles Venturia canescens deliver proteins. Here, we take standpoint wasps review current knowledge on virus by lineages. Then, based genomic data PDVs exogenous discuss steps required transform into vehicles molecules observe today. Finally, how manipulate host physiology ensure parasitism success, highlight possible advantages compared with
