Genetic engineering applications in plant improvement are very well known because of the commercialization of several transgenic maize hybrids, particularly in the case of insect and herbicide resistant events. New developments include a wider range of transgenic resistance to abiotic and biotic stresses. These developments will be illustrated with the ongoing research on Mal de Río Cuarto virus (MRCV) and frost resistance at INTA. A second generation of transgenic plants includes events expressing oral vaccines. This will be exemplified with the case of Newcasttle disease virus (NDV) which is very important in chicken production. On the other hand, the release of transgenic plants resistant to insects may cause the selection of Bt resistant insects, that has to be monitored for better risk managements. Results on the population dynamics of molecular markers in Diatraea saccharalis provide a useful tool for this monitoring.
