GENOME VEGETAL RECOMBINE, MITOCHONDRIE ET CELLULE LE CONTENANT, ET PROCEDE DE SELECTION D'UNE STERILITE MALE CYTOPLASMIQUE CHEZ UNE PLANTE DU GENRE CICHORIUM

摘要

The invention discloses a recombinant plant genome, characterised in that it comprises specific chicory genes and a nucleotide sequence conferring male sterility, carried by the Helianthus annuus orf 522 sequence, or by a sequence with at least 50 % homology with the said orf 522 sequence. It also features a mitochondrion, a cytoplasm or a recombinant plant cell containing such a genome. Finally it discloses methods for producing and selecting plants of the Cichorium genus with cytoplasmic male sterility.
