DAYFLOWER FLAVONOID 3',5'-HYDROXYLASE GENE

摘要

Disclosed are: a high-level-expression-type F3'5'H gene which enables the production of a blue moth orchid or the like; and a method for producing an Orchid family plant having a blue flower color by using the gene. Specifically disclosed are: a gene encoding a flavonoid 3',5'-hydroxylase derived from dayflower (Commelina communis), which comprises the amino acid sequence depicted in SEQ ID NO:2 or an amino acid sequence having at least 90% homology to the amino acid sequence depicted in SEQ ID NO:2; and a method for producing an Orchid family plant having a blue flower color, which comprises the steps of transfecting an Orchid family plant having a white flower color with the aforementioned gene, a gene encoding dihydroflavonol 4-reductase derived from trenia (Trenia fournieri) or gerbera, a gene encoding flavanone 3-hydroxylase, and a gene encoding an anthocyanidin synthase, and causing these genes to express.
