Resistance against bacterial and fungal-pathogens

Molecular basis for resistance against several diseases in a variety of crop plants has now been worked out. It has been shown in many cases that disease resistance is controlled by single resistance genes in the host that specifically recognizes pathogen strains containing complementary avirulence genes.

A number of resistance genes from hosts and the corresponding avirulence genes from the pathogens have also been isolated and cloned in many cases. This has facilitated the development of disease resistant transgenic crop plants. Several examples are now available, where transgenic plants with resistance against bacterial and fungal pathogens have been produced. Some examples are given.
