PLANTS RESISTANT TO INFECTION BY PVX

摘要

A DNA sequence encoding a PVX replicase gene obtained from ORF1 of a PVX genome is provided. A plant gene containing the PVX replicase coding region is also provided as is a truncated derivative of the PVX replicase gene. A PVX replicase gene is inserted into a plant to confer resistance to the plant against PVX infection when the PVX replicase gene is sufficiently expressed.
