Abstract
Although many cases of plant resistance to virus disease are known, we do not yet have a full understanding of how any kind of resistance works biochemically.
This paper classifies resistance mechanisms into three types: non-host immunity; constitutive (genetically controlled) resistance; and induced resistance, on the basis of possible underlying mechanisms.
The present state of knowledge of genetical control and biochemistry of representative examples is reviewed.
The nature of the change in a virus which makes it virulent on a previously resistant host is considered.
Future exploitation of resistance mechanisms in crop protection may be facilitated by genetic engineering techniques.
Some possibilities, requirements and difficulties are discussed.
