Carnation variety 29821 flowers have a novel colour due to the biosynthesis of the anthocyanin pigment delphinidin. This pigment is not produced in non-transgenic carnation. The transgenic lines were derived from the parent cultivar which is a pink coloured carnation. The genes introduced into the transgenic carnation lines included a functional dihydroflavonol reductase encoding gene (dfr) from petunia, and a gene (hf1) 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.

29821 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 transgenic lines were derived from the parent cultivar which is a pink coloured carnation. The genes introduced into the transgenic carnation lines included a functional dihydroflavonol reductase encoding gene , a gene encoding the enzyme flavonoid 3', 5'-hydroxylase (F3'5'H), and an anthocyanin-3',5'-methyltransferase 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.
