PLANT ENHANCEMENT BY GENETIC ENGENEERING TRADITIONAL PLANT IMPROVEMNT CROSSING BETWEEN SPECIES BIOLOGICALLY RELATED TOLERANT PARENTAL Wild PARENTAL SUSCEPTIBLE Cultivated CULTIVAR RESISTANT Selection and crossing during generations 2 PLANT ENHANCEMENT BY GENETIC ENGENEERY Isolation Genes Cloning Transformation Incorporation to plant AGRONOMICALLY INTERESTING GENS TRANSFORMATION Regeneration in vitro IMPROVED CULTIVAR Genetically modified organisms (GMOs) can be defined as: organisms in which the genetic material (DNA) has been altered in a way that does not occur naturally by mating or natural recombination. As an application of modern biotechnology, this technique allows selected individual genes to be transferred from one organism into another, also between non-related species What are GMOs? Traditional cross-breeding requires years Transgenic plants are quickly developed by insertion of single gene responsible for a particular trait GLOBAL AREA OF BIOTECH CROPS CROPS AND TRAITS M Cmara, 2006 3 4 MOST IMPORTANT VEGETABLES TRANSFORMATIONS GM M Cmara, 2006 IMPORTANT VEGETABLE TRANSFORMATIONS: !
