Abstract
Abstract Transgenic plants are disclosed which are resistant to virus infection by Potato Virus X and Potato Virus Y. Plant genes and transformation vectors are also disclosed. Potato plants, for example, Russet Burbank variety, are made resistant to dual infection by Potato Virus X and Potato Virus Y by transforming the plant to express the coat proteins of the two viruses.
