The non-enveloped viral particles have an estimated diameter of 32 +/- 2 nm. Three major proteins were found in virions, with estimated sizes of 102.0 +/- 2.1, 95.8 +/- 2.0 and 92.4 +/- 1.5 kDa for AnchV as determined by polyacrylamide gel electrophoresis. After denaturing agarose gel electrophoresis, the genome of AnchV appeared to be a tri-segmented single-stranded RNA with fragment sizes of 4.1 +/- 0.2, 2.8 +/- 0.2 and 1.65 +/- 0.2 kb. In addition to a high virulence towards its original host, AnchV also caused high mortality in larvae of two other potato tuber moth species, Phthorimaea operculella (Zeller) and Symmetrischema (tangolias) plaesiosema (Turner). Electron microscopy confirmed that AnchV replication occurs in the cell cytoplasm, mainly in vesicles. Several important characteristics exhibited by this Virus differ from those reported for known families of insect viruses. Thus, AnchV might be member of a new taxonomic group. specialized Small rna virus Phthorimaea operculello Symmetrischema plaesiosema Lepidoptera Gelechiidae Host specificity Potato pest Biological control 076 99 2 204-211 2008 0022-2011 https://www.documentation.ird.fr/hor/fdi:010044064 10.1016/j.jip.2008.06.007 0022-2011 [F B010044064] https://www.documentation.ird.fr/hor/fdi:010044064 https://www.documentation.ird.fr/intranet/publi/2008/11/010044064.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-12-05 2017-08-23 fdi:010044064 fre
