NOVEL NUCLEIC ACID SEQUENCES AND THEIR USE IN METHODS FOR ACHIEVING A PATHOGENIC RESISTANCE IN PLANTS

摘要

The invention relates to a method for increasing the resistance to pathogens that penetrate mesophyll cells in a plant, or in an organ, tissue or cell of a plant. Said method is characterised in that the callose synthase activity in the plant, or in an organ, tissue or cell of said plant is reduced in comparison to control plants.
