Abstract(s)

Concerns about Biosafety of transgenic crops have led Governments to implement regulations to assess potential risks before genetically engineered crops are approved for commercialization. Each genetically modified crop regulatory approval is preceded by years of intensive research demonstrating that the crop is safe to humans, animals as well as other non-target beneficial organisms, plants and environment. In a recent study, we have demonstrated that the major factor influencing proteomic differences of transgenic vs. non-transgenic plants may be the in vitro culture stress imposed during plant genetic transformation. This study lead us to question the dimension of transgenic vs. non transgenic differences as compared with the ones we know that can happen any time, due to environmental stresses.
