Abstract
Linoleic acid is converted into &ggr;-linolenic acid by the enzyme &Dgr;6-desaturase. The present invention is directed to isolated nucleic acids comprising the &Dgr;6-desaturase gene. More particularly, the isolated nucleic acid comprises the promoter, coding region and termination regions of the &Dgr;6-desaturase gene. The present invention provides recombinant constructions comprising the &Dgr;6-desaturase coding region in functional combination with heterologous regulatory sequences. The nucleic acids and recombinant constructions of the instant invention are useful in the production of GLA in transgenic organisms.
