The possibility of altering the bacterial behavior through the use and molecules that act in the signaling between bacteria represents a very interesting potential for the use against some plant diseases. Recently, plants transformed with the X. fastidiosa rpfF gene responsible for the DSF regulatory signal were shown to be more resistant to CVC and to Citrus canker. Once the transgenic plants presented satisfactory results, the next step would be to investigate the possibility of translocation of the DSF molecules from transgenic rootstocks to non-transgenic scion in order to evaluate the level of tolerance, in which the presence of these molecules would be able to confer. This hybrid plant model - only with the transgenic graft - would enable the production of non-transgenic fruits more tolerant to citrus diseases.
