Introduction Expand

Through event 123.8.12 (OECD Unique Identifier FLO-4Ø689-6), carnation produces mauve-colored flowers, whereas the non-GM parent plant has white flowers. The color change was achieved by introducing from Petunia and Viola sp. two genes in the anthocyanin biosynthesis pathway. The two genes encode two enzymes - dihydroflavonol 4-reductase (dfr) and flavonoid 3'5' hydroxylase (f3'5'h). In addition, this genetically engineered carnation contains a marker gene SuRB, which confers the plant tolerance to sulphonylurea-type herbicides.

Characteristics of Dianthus caryophyllus (Carnation) Expand

Center of Origin Reproduction Toxins Allergenicity

The species is native to the Mediterranean region, including Europe, Asia, and northern Africa.

Carnation flowers are pollinated primarily by butterflies and sometimes by other insects.

The parts of the carnation plants are not thought to be toxic, and the flowers are considered edible.

Occupational exposure to carnation flowers has been associated with allergic reactions in humans.

Donor Organism Characteristics Expand

Latin Name Gene Pathogenicity
Viola hortensis F3’5’H

Viola hortensis is a flowering plant with no human toxicity or allergenicity reported in the literature. There is a report on antithrombin effect caused by the extracts of Viola hortensis.

Petunia X hybrida dfr

Petunia X hybrid is a flowering plant. No toxicity to human or animals are reported. No allergy is linked to petunia exposure. In fact, petunia is considered to be among the safe flower plants to people who are allergic to flower pollens

Nicotiana tabacum surB

Nicotiana tabacum is cultivated tobacco and it is well known for its health effects. Adverse health effects can result from human exposure via inhalation of tobacco smoke, or dermal or oral intake of tobacco products.
