DNA AND VECTOR TO REGULATE THE EXPRESSION OF THE SYNTHASE GENE OF THE LACRIMATORY FACTOR, A METHOD TO REGULATE THE EXPRESSION OF THE GENE OF THE SYNTHESIS OF THE LACRIMATORY FACTOR THROUGH ITS USE, AND PLANT WITH REGULATED EXPRESSION OF THE GENE OF THE SYNTHESIS OF THE LACRIMATORY FACTOR.

摘要

A construct comprising a DNA operably linked to a regulatory sequence, in which said DNA suppresses the expression of a protein or a polypeptide that possesses enzymatic activity that produces tear factor, in which said DNA comprises a sequence selected from the (i) , (ii), (iii), (iv) and (v) that follow, in both orientations, sense and antisense: (i) a DNA sequence of SEQ ID NO. 1, 5, 7, 9, 11, 13 or 15; (ii) a DNA sequence that has an identity of at least 75%, with a DNA sequence represented by SEQ ID NO. 1, 5, 7, 9, 11, 13 or 15; (iii) a regulatory DNA sequence located immediately on the upstream side and that regulates the expression of a DNA sequence represented by SEQ ID NO. 1, 5, 7, 9, 11, 13 or 15, of a genomic DNA of the genus Allium; (iv) a DNA sequence located between the DNA sequence cited in (i) and the regulatory DNA sequence cited in (iii), of a genomic DNA of the genus Allium; and (v) a DNA sequence that is at least 18 nucleotides in length from the DNA sequence cited in (i), (ii), (iii) or (iv).
