First transgenic geminivirus-resistant plant in the field

Nature Biotechnology volume 27, pages 1086–1088 (2009)Cite this article

A Correspondence to this article was published on 01 December 2009

To the Editor:

The article by Lucioli et al.1 in last year's June issue states not only the drawbacks to the use of pathogen-derived resistance (PDR) for geminiviruses, but also that RNA interference (RNAi) thus far has not proved to be a robust technology for obtaining plants resistant to these viral pathogens. We present here data on the generation of two transgenic geminivirus-resistant common bean lines. On the basis of these results, we feel that the conclusions of Lucioli et al.1 are premature.
