Gene Functions in Host-Parasite Systems

There are two important reasons for trying to explain the nature of host-parasite specificity. The first is to be able to manipulate and improve specific resistance and hence deploy it more effectively against crop plant parasites. The second reason is that an understanding of the mechanism of specificity will increase knowledge of the nature and control of gene action in eukaryotes an end with broad philosophical and practical rewards. My interest in specificity began with work in the early 50’s on breeding tomatoes for resistance to the fungal parasite Cladosporium fulvum and with the consequences of releasing resistant varieties and seeing that their resistance was race specific.
