Abstract
The invention relates to a method of modifying a plant virus or its effects, which comprises incorporating genetic material into a plant and infecting said plant with a plant virus, whereby expression of the incorporated genetic material modifies the plant virus or its effects. In a preferred embodiment, expression in the plant of the incorporated genetic material causes attenuation of the symptoms of attack on the plant by a plant virus.
Claims14
A method of protecting a plant against the effects of a plant virus, said method comprising;
- transferring a DNA fragment into a plant, wherein the DNA fragment is complementary to a symptom-attenuating satellite RNA sequence of a first Cucumovirus,
- said DNA fragment being capable of being transcribed in said plant and inherited by a progeny plant;
- and when transcribed, or when transcribed and translated in said plant or progeny plant,
- said DNA fragment protects said plant by attenuating the symptoms brought about by infecting said plant with a second Cucumovirus.
