Abstract:
Tobacco mosaic virus (TMV) is a positive-sense plant RNA virus which has a wide host range and a worldwide distribution. Other than a troublesome pathogen, TMV is regarded as a model system pioneering biologic research for a century. The tomato strain of TMV has been recognized to be a distinct tobamovirus as the tomato mosaic virus (ToMV). Recombination has been increasingly recognized as an important factor generating genetic diversity in many RNA viruses. However, it is still unclear whether recombination can function in driving the evolution of tobamoviruses. Herein, based on sequence comparison, we found three recombinants involving each viral gene, all of which might be derived from homologous or aberrant homologous recombination between TMV and ToMV. The study provided evidence that recombination did contribute to the genetic diversity of tobamoviruses.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
