Plants just say NO to pathogens
Article Abstract:
Production of nitric oxide (NO) is sufficient to activate parts of the defence response in plants seeking to resist bacterial, fungal, nematode and viral infections. It has been shown that NO synergizes both with reactive oxygen intermediates and with an endogenous factor that is regulated by salicylic acid and potentiates the overall defence response. It is clear that NO determines the hypersensitive response and defence-gene activation, but there are still uncertainties on a number of issues, including the extent to which the generation of NO is needed to stop a pathogen's growth.

Transgene risk is low
Article Abstract:
Research indicates that oilseed rape, Brassica napus L., has little chance of taking on transgenes from genetic modification through the introgressive hybridization process. Gene flow occurs when unmodified populations are in close proximity to one another. The transgene movement from a genetically modified to a natural plant would be more likely in the event of enhanced selection ability.
