Abstract
The invention features a method of producing a grape somatic embryo having resistance to a plant pathogen, the method including the steps of (a) culturing a grape somatic embryo in a first liquid culture medium that includes a plant growth regulator and a phytotoxin from a plant pathogen; (b) exchanging the first liquid culture medium for a second liquid culture medium not including the phytotoxin; (c) recovering a living grape cell or grape cell cluster from the second liquid culture, the living cell or cell cluster being resistant to the pathogen; and (d) culturing the grape cell or grape cell cluster in a third culture medium to produce a grape somatic embryo.
