Part 3 
Practical use of molecular
studies
The results of investigation on the mechanisms of pathogenicity and resist-
ance in infectious plant diseases are primarily important as a fundamental
basis for the development of highly efficient plant disease and pest control
measures. These investigations have not changed the plant protection strategy
(and they could not have changed it): similar to the conventional systems,
there are two prevailing approaches: chemical protection and genome modifi-
cation to develop cultivars resistant against pathogens. However, both the
methodologies and capabilities of these approaches have cardinally changed.
