Primulaceae

 

(primroses), a family of dicotyledonous plants. Most of the species are annual or perennial herbs; a few are subshrubs. The leaves are mainly simple, and some are glandular or farinose. The flowers are bisexual and usually regular; the sepals and petals are fused. Heterostyly characterizes many of the plants. There is generally a superior ovary; some are partly inferior. The fruit is a capsule or, occasionally, a pyxis.

There are 30 genera of Primulaceae, embracing more than 800 species. They are found throughout the world but primarily in the temperate and cold zones of the northern hemisphere. Many species are found in mountainous regions and in the arctic. The USSR has 18 genera, comprising about 145 species. These include the genera Lysimachia, Cyclamen, Androsace, Trientalis, and Hottonia. Several species, including some of the genera Primula and Cyclamen, are ornamentals.

The invention relates to the production of a transgenic organism, preferably a transgenic plant or a transgenic microorganism, having an increased content of fatty acids, oils or lipids having .DELTA.6 double bonds due to the expression of a .DELTA.6-desaturase from Primulaceae. The invention additionally relates to expression cassettes containing a nucleic acid sequence, a vector and organisms containing at least one nucleic acid sequence or an expression cassette.

In the same region the popular name of a slender herbaceous plant (Androsace strigillosa, Litang) belonging to Primulaceae family is mdzo mo sna khrag, "nose blood of a female dzo" owing to its small cluster of red flowers which are associated to the blood that is often noticeable, according to informants, in the nasal cavity of this animal.
Primulaceae contains some real surprises, with cyclamen being at the top of the list.
