Transgenic pomaceous fruit with fire blight resistance

摘要

The present invention relates to a method of conferring resistance against fire blight to pomaceous fruit scion or rootstock cultivars by transforming such cultivars with a gene which encodes for lytic proteins. Such transformation can be effected by bacterial infection or propulsion of particles into cell interiors. Once transformation has taken place, the cultivar is regenerated to a transgenic pomaceous fruit tree. This technique is particularly useful in treating apple and pear cultivars.
