Abstract: Provided are transformed chrysanthemum plants having blue flower color, their self-fertilized progenies or cross-fertilized progenies thereof, a vegetative propagated plants thereof, and a part, a tissue or a cell of the plant body. Anthocyanin 3?,5?-O-glucosyltransferase gene (CtA3?5?GT) derived from Clitoria ternatea and flavonoid 3?,5?-hydroxylase gene derived from Campanula (CamF3?5?H) are coexpressed in chrysanthemum petals.

Abstract: 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?-hydroxylase (F3?5?H) is caused to be expressed in a chrysanthemum plant using a transcriptional regulatory region for a chrysanthemum-derived flavanone 3-hydroxylase (F3H) gene.

Abstract: Disclosed are a method for controlling flavonoid synthesis in a chrysanthemum plant or non-chrysanthemum plant by genetic recombination technology using a transcriptional regulatory region useful for altering flower color, a method for modifying anthocyanins, a method for producing a chrysanthemum plant or non-chrysanthemum plant containing modified anthocyanins in the petals thereof, and a chrysanthemum plant or non-chrysanthemum 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?H gene, such as the nucleotide sequence indicated in SEQ ID NO. 15, is used.

Abstract: Provided is a bacterium which is capable of producing an organic acid and is modified so as to have an enhanced 2-oxoglutarate dehydrogenase activity as compared with that of an unmodified strain. An organic acid such as succinic acid can be produced by culturing the bacterium.
