Disclosed are: a method for producing a chrysanthemum plant having delphinidin-containing petals using a transcriptional regulatory region for a chrysanthemum-derived flavanone 3-hydroxylase (F3H) gene; and a chrysanthemum plant, a progeny or a vegetative proliferation product of the plant, or a part or a tissue of the plant, the progeny or the vegetative proliferation product, and particularly a petal or a cut flower of the plant. In the method for producing a chrysanthemum plant having delphinidin-containing petals, a flavonoid 3',5&#x2032;-hydroxylase (F3&#x2032;5&#x2032;H) is caused to be expressed in a chrysanthemum plant using a transcriptional regulatory region for a chrysanthemum-derived flavanone 3-hydroxylase (F3H) gene.

Method for production of chrysanthemum plant having delphinidin-containing petals

Disclosed are a method for controlling flavonoid synthesis in aplant or non-plant by genetic recombination technology using a transcriptional regulatory region useful for altering flower color, a method for modifying anthocyanins, a method for producing aplant or non-plant containing modified anthocyanins in the petals thereof, and aplant or non-plant, progeny thereof, or vegetatively propagated products, part or tissue thereof transformed with the regulatory region. In the method according to the present invention, an expression vector or expression cassette containing a transcriptional regulatory region of perilla anthocyanin 3-acyltransferase gene, such as a nucleic acid containing the nucleotide sequence indicated in SEQ ID NO. 1, or a transcriptional regulatory region of pansy F3'5&#x2032;H gene, such as the nucleotide sequence indicated in SEQ ID NO. 15, is used.
