Resumen:
Citrus canker provoked by Xanthomonas axonopodis pv. citri is a bacterial disease causing severe losses in all citrus-producing areas around the world. Xanthomonas infection is considered endemic disease in Northeast and Northwest Argentina, affecting as much as 10% of commercial citrus plantations. There is not known natural resistance neither in orange varieties nor in rootstocks used for grafting of commercial cultivars. To introduce resistance to this bacterial disease, plants of Pineapple sweet orange were transformed with a genetic constructs allowing constitutive accumulation of dermaseptin in the apoplastic space. As compared to non-transformed controls, the transgenic plants showed bacterial resistance levels varying between 40-60% in infection assays conducted with X. axonopodis pv. citri under growth chamber conditions.
