Title:
TRANSGENIC PLANT OF THE SPECIES BETA VULGARIS HAVING ENHANCED RESISTANCE TO CERCOSPORA
Document Type and Number:
WIPO Patent Application WO/2013/050024
Kind Code:
A3
Abstract:
The invention relates to a transgenic plant of the species Beta vulgaris, into the genome of which a nucleic acid was stably integrated. From said nucleic acid RNA is transcribed in the plant, wherein RNA formed in the event of an infestation of the plant with a fungus of the genus Cercospora can be taken up by said RNA so that the Cercosporin biosynthesis in the fungus is impaired in such a manner that biotrophic growth phase of the fungus is inhibited and the plant has an enhanced resistance to the fungus compared with a control plant.
