Abstract
The making of plant cells which contain antisense RNA (aRNA) complementary to the mRNA of an alfalfa mosaic virus is disclosed. Construction of such aRNA genes and transformation thereof into plant cells is also taught. Such cells are relatively resistant to infection by the target virus when compared with cells not containing the aRNA. Methods and DNA molecules useful for producing plant cells containing said aRNA are also disclosed.
