Flexible filamentous viruses make up a large fraction of the known plant viruses, but in comparison with those of other viruses, very little is known about their structures. We have used fiber diffraction, cryo-electron microscopy, and scanning transmission electron microscopy to determine the symmetry of a potyvirus, soybean mosaic virus; to confirm the symmetry of a potexvirus, potato virus X...
The allotetraploid plant Nicotiana tabacum (common tobacco) is a major crop species and a model organism, for which only very fragmented genomic sequences are currently available. Here we report high-quality draft genomes for three main tobacco varieties. These genomes show both the low divergence of tobacco from its ancestors and microsynteny with other Solanaceae species. We identify over 90,...
Abstract: Potato virus Y a type species of the genus potyvirus infects several crops in the family solanaceae. PVY isolated from field infected peppers was identified on the basis of host reaction, serological and molecular characterization. The result of ELISA, Immunoblot electrophoresis and Immuno Capture Reverse Transcription Polymerase Chain Reaction (IC-RT-PCR) indicated that...
PeSMV was originally isolated in Argentina from diseased Capsicum annuum plants and classed as a possible member of the potyvirus group on the basis of morphological, biological, and immunological evidence (Feldman and Gracia, 1977). Although information concerning its economic significance is still imprecise, the virus is present in most pepperproducing areas and yields are drastically reduced...
