The present invention is directed to promoters of flax conlinin and .omega.-3 desaturase genes. The promoters guide high levels of the expression exclusively in flax developing seeds. This specific expression pattern concomitant with the biosynthesis of storage lipids and proteins make these promoters particularly useful for seed-specific modification of fatty acid and protein compositions in plant seeds.
