METHOD FOR ENHANCING RESISTANCE IN PLANTS

摘要

The present invention provides a method for inducing or enhancing resistance in plants by supplying to the plant a virally encoded booster sequence comprising the 5' proximal region of the potyvirus genome or by supplying other sequences encoding suppressors of gene silencing alone or in combination. Supplying the booster sequence to a plant, by means of stable transformation into the genome of the plant or introduced by expression from a plant viral expression vector, induces or enhances resistance in a plant against a broad range of pathogens, including viral, fungal and bacterial infectious agents.
