1.The genetically modified organism to be placed on the market, is a 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 pCGP1991, and resulting in line SHD-27531-4.The genetically modified carnation contains the following DNA in three cassettes:
(a)Cassette 1The petunia dfr gene encoding dihydroflavonol 4-reductase (DFR), a key enzyme in the anthocyanin biosynthetic pathway, including its own promoter and terminator.
(b)Cassette 2The promoter sequence from snapdragon chalcone synthase gene, flavonoid 3′5′-hydroxylase (f3′5′h) from Viola hortensis cDNA encoding F3′5′H, a key enzyme in the anthocyanin biosynthetic pathway, and the terminator from the D8 petunia gene encoding a putative phospholipid transfer protein.These two cassettes were inserted into the plant genome to obtain the desired flower colour.
(c)Cassette 3The Cauliflower mosaic virus 35S promoter, the 5′-untranslated region from the petunia gene encoding 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, including its own terminator. This trait was used as a marker in the selection of transformants.
2.The unique identifier of the genetically modified carnation shall be SHD-27531-4.
