An imperiled plant is somewhat like a person. It has to depend on the defense mechanisms, both structural and metabolic to prevent harmful effects of the pathogens. It includes preexisting defense structures surface waxes, structure of epidermal cell walls, position of stomata and lenticles, thick cell walls, leaf hairs, defense structures formed in response to infection by the pathogen, histological defense structures, metabolic (biochemical) defense preexisting biochemical defense, metabolic defense induced by the attacking pathogen, defense through the hypersensitive reaction, defense through increased levels of phenolic compounds, "common" phenolics etc. Plants also activate a specific set of defense genes in response to assault. Recent technologies have enabled us to have plants with "useful genes" only, thus providing better crops in larger number. Unlike traditional plant breeding, which involves the crossing of hundre

The infection of a susceptible plant with a non-pathogen leads to resistance to a pathogen.

Metabolic Defense Induced by the Attacking Pathogen

Fungitoxic Phenolics released from nontoxic phenolic complexes

Also, it is clear that gene transfer using rDNA techniques is substantially different from the processes that govern gene transfer in traditional breeding. The extent to which these processes differ will become increasingly clear as we gain a better understanding of the processes governing gene movement, expression and regulation.
