摘要：

The theory of pathogen-derived resistance suggests that pathogen resistance genes can be developed from a pathogen’s own genetic material. For example, transgenic plants expressing plant virus coat protein genes are often virus resistant. Non-structural virus genes also have been expressed in plants, with mixed results. Recent experiments suggest that, at least in some cases, resistance may be RNA-mediated. In all cases the exact mechanism of this resistance remains a mystery. This review discusses examples of pathogen-derived resistance for members of the potyviridae family of plant viruses and offers some possible mechanisms to account for this intriguing phenomenon. © 1994 Academic Press.
