Concepts like bio-security and bioethics have been put into the test whit the rapid advance of the Biotechnology. Specifically the plant’s genome manipulation is worthy to be reconsidered by the ethical and juridical point of views. Plants varieties and products obtained by these new biotechnological methods are important achievements but also can be a risk for the human health and the environment. On the other hand, a monopoly of commercial exploitation for the holder of the patent and other exclusives titles like Certificates of Vegetable Obtaining can leave out the fair access to the technological progresses. In this work we make a valuation about those aspects of Biotechnology related with the genome of the plants and their juridical protection.
