CINERARIUM-DERIVED CHROMOSOMAL DNA INVOLVED IN SYNTHESIS OF FLAVONOID, AND USE THEREOF

摘要

Disclosed are: a novel cineraria-derived polynucleotide which can act as a promoter for a coding region of flavonoid 3',5'-hydroxylase (F3'5'H); and a novel F3'5'H gene construct which carries the polynucleotide. Specifically disclosed are: a cineraria-derived petal-specific promoter which is selected from the group consisting of (1) a polynucleotide having the nucleotide sequence depicted in SEQ ID NO:9 and (2) a polynucleotide which can hybridize with the polynucleotide having the nucleotide sequence depicted in SEQ ID NO:9 under stringent conditions and can act as a promoter for a coding region of flavonoid 3',5'-hydroxylase (F3'5'H); and a gene construct for inhibiting the expression of a gene in an RNAi method, which has, as a loop, a polynucleotide comprising the whole or a part of a first intron of the novel cineraria-derived polynucleotide.
