1. The genetically modified organisms to be placed on the market as product, hereinafter ‘the product’, are cut flowers of carnation ( Dianthus caryophyllus L.), with modified flower colour, derived from a Dianthus caryophyllus L. cell culture, and transformed with Agrobacterium tumefaciens , strain AGL0, using the vector pCGP2355, and resulting in line 26407.
The product contains the following DNA in three cassettes:
(a)
Cassette 1
The promoter from snapdragon chalcone synthase gene, the petunia cytochrome b5 (difF) cDNA encoding a cytochrome b5 protein to enhance activity of F3′5′H, and the terminator from a petunia gene encoding a phospholipid transfer protein homologue.
(b)
Cassette 2
The petunia flavonoid 3′5′-hydroxylase cDNA ( f3′5′h ) encoding F3′5′H, a key enzyme in the anthocyanin biosynthetic pathway and the promoter and terminator of a Dianthus caryophyllus anthocyanidin synthase ( ans ) gene.
These two cassettes were inserted into the plant genome to obtain the desired flower colour.
(c)
Cassette 3
The Cauliflower mosaic virus 35S promoter, the 5'untranslated region of the petunia gene coding for chlorophyll a/b binding protein, the SuRB ( als ) gene coding for a mutant acetolactate synthase protein (ALS) derived from Nicotiana tabacum , which confers tolerance to sulfonylurea. This trait was used as a marker in the selection of transformants.
2. The consent shall cover progeny derived through vegetative reproduction of the genetically modified carnation ( Dianthus caryophyllus L., line 26407).
