Flax (<i>Linum usitatissimum </i>L.) seed-specific promotors

摘要

The present invention is directed to promoters of flax conlinin and ω-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.

主权项

1. An isolated nucleic acid molecule comprising a Linum LuFad3 promoter operably linked to a heterologous gene of interest, wherein said Linum LuFad3 promoter comprises:
a) the nucleotide sequence of SEQ ID NO: 9 or 10, or b) a fragment of the nucleotide sequence of SEQ ID NO: 9 or 10,wherein said fragment is capable of directing seed-specific expression of said heterologous gene of interest in a plant.
