HOST/PATHOGEN INTERACTIONS AND POTENTIAL OF IN VITRO SELECTION TECHNIQUES TO OBTAIN DISEASE RESISTANT PLANTS
Keywords:
fitotoxins, tissue culture, biotic stresses resistance.Abstract
Pathogens establish complex interactions pattems with plants, which can be compatible or not. Considering the different plants which daily supply human needs, and all diseases caused by viroses, bacteria, fungi and nematodes which can cause damage to these plants, the number of host/pathogen combinations is immense. Besides that, the exchange of plants between different regions and the intensivo system of agriculture helped the dissemination and evolution of these combinations. Tissue culture techniques, which provide a efficient control of the environment conditions, and tum possible to analyze a wide number of genetic material in restrict space, can help the study of host/pathogen interactions, and breeding programs on the development of disease-resistant plants.
