Description
Carnation variety 29952 flowers have a novel flower colour due to the biosynthesis of the anthocyanin pigment delphinidin. This pigment is not produced in non-transgenic carnation. The genes introduced into the transgenic carnation lines included a functional dihydroflavonol reductase encoding gene (dfr) from petunia and a gene encoding the enzyme flavonoid 3', 5'-hydroxylase (F3'5'H). Expression of the F3'5'H encoding gene allows for the production of blue coloured delphinidin anthocyanin pigments.
Recipient Organism or Parental Organisms
The term Recipient organism refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas Parental organisms refers to those that were involved in cross breeding or cell fusion.

Notes regarding the genetic elements introduced or modified in this LMO
29952 was developed using recombinant DNA techniques to produce flowers with a unique violet/mauve colour by introducing four genes that function together in the biosynthesis of the anthocyanin pigments related to delphinidin.
The genes introduced into the transgenic carnation lines included a functional dihydroflavonol reductase encoding gene (dfr), a gene encoding the enzyme flavonoid 3', 5'-hydroxylase (F3'5'H), an anthocyanin-3',5'-methyltransferase gene and a flavone synthase gene.
Expression of the F3'5'H encoding gene allows for the production of blue coloured delphinidin anthocyanin pigments, which are not normally found in carnations. Anthocyanin-3',5'-methyltransferase (AMT) methylates delphinidin-3-glucoside to produce anthocyanins with a novel hue. Production of flavones increases the blue hue of the flower colour.
