Melon (Cucumis melo)
Summary
The patents granted to Biosem (assignments changed to Groupe Limagrain Holding) in the United States and in Europe claim
- the production of transgenic diploid melon (C. melo) plants having a DNA molecule introduced by A. tumefaciens;
- a method to transform cotyledons of C. melo by contacting with A. tumefaciens;
- the insertion of a sequence conferring resistance to cucumber mosaic virus; and
- media for inducing shoot formation from transformed cotyledons and for regeneration of transformed plantlets.

Title – Transgenic plants belonging to the species Cucumis melo
Process for the production of transgenic diploid melon plantlets by transforming cotyledons of C. melohaving a gene of interest introduced via A. tumefaciens. The process includes media components and protocols for inducing formation of transformed shoot buds and formation of plantlets. |

Title – Transgenic plants belonging to the species Cucumis melo
Granted US 5789656 is a divisional of now granted US 5422259. Process for the production of transgenic diploid melon plantlets by transforming cotyledons of C. melohaving a gene of interest introduced via A. tumefaciens. Transgenic diploid melon having the gene of interest, i.e. gene for cucumber mosaic virus, are also claimed. |

Title – Transgenic plants belonging to the species Cucumis melo
Granted US 6198022 is a divisional of now granted US 5789656 (see above), which is a divisional of now granted US 5422259 (see above). The process described above applied to the production of cucumber mosaic virus-resistant plants by expression of the viral capsid protein (this is a divisional application of the patent listed immediately above). |

Title – Transgenic plants of the species Cucumis melo
Designated contracting States at the time of grant are: Belgium (patent lapsed as reported by INPADOC), Germany (patent lapsed as reported by INPADOC), Spain, France (patent lapsed as reported by INPADOC), United Kingdom (patent lapsed as reported by INPADOC), Greece, Italy, Luxembourg (patent lapsed as reported by INPADOC), Netherlands The process for the production of transgenic diploid melon plantlets is very similar to the process claimed in the related United States patents. Media components for shoot buds induction and plantlet development are also part of the claims. |
