Embodiment 1

[0100] Example 1 : Simulation of the Cochrome Effect of Flavonoids on Anthocyanins

[0101] In order to simulate the co-coloring effect of flavonoids on anthocyanins, anthocyanins were first prepared. Cyanin is extracted and purified from the petals of the Chinese rose variety "Rote Rose" (rose cv. "Rote Rose"). Delphin is obtained from Verbena species "Tapien Violet" (vberbena cv. "Tapien Violet" or vberbena variety Sunmaref TP-V ("Tapien Violet") ("Tapien" is a Trade Mark registered in The pigment extracted from the petals of Japan)) is purified by alkaline hydrolysis. Malvin and Luteolin 7-O-glucoside were purchased from Funakoshi Co., Ltd., Japan.

[0102] To the various anthocyanins thus prepared, flavone (Luteolin 7-O-glucoside) was added at a molar concentration ratio of 0, 1, 2, and 4 equivalents in a pH 5.0 buffer, and the absorption spectrum was measured. As anthocyanins, Cyanin (Cyanidin-3,5-diglucoside (Cyanidin3,5-diglucoside)), delphin (Delphin) (Delphin 3...

Embodiment 2

[0111] Embodiment 2 (reference example) : Introducing F3’5’H#4 from pansy to the rose variety "Lavande" 0 gene and flavone synthase gene from perilla

[0112]The plasmid pYFS3 containing the flavone synthase gene from perilla described in Japanese Patent Application Laid-Open No. 2000-279182, pYFS3 was digested with XbaI, blunted at the end, and further digested with BamHI to obtain perilla flavone synthase of about 1.8 kb Gene fragment. On the other hand, pSPB906 described in WO2005 / 017147 was digested with XhoI, blunted at the end, and further digested with BamHI. Between the blunt end and the BamHI cleavage site, the flavone synthase gene fragment of perilla was inserted to obtain 906-pYFS3. 906-pYES3 was inserted into the El 2 There is a perilla-derived flavone synthase gene between the 35S promoter and the D8 terminator (both described in WO2005 / 017147).

Embodiment 3

[0121] Example 3 : Introducing the F3’5’H#40 gene from pansy and Flavone synthase gene from Butterfly

[0122] The Butterfly grass-derived flavone synthase gene described in the report of Akashi et al. (Plant Cell Physiol 40, 1182-1186, 1999) was inserted into the EcoRI and XhoI sites of plasmid pBluescript IISK(-), and the obtained plasmid was designated as pSPB426. After it was digested with KpnI, the end was blunted, and further digested with BamHI to obtain a flavone synthase gene fragment of about 1.7 kb from Butterfly. On the other hand, pSPB906 described in WO2005 / 017147 was digested with XhoI, blunted at the end, and further digested with BamHI. Between the blunt end and the BamHI cleavage site, the above-mentioned flavone synthase gene fragment of Butterfly grass was inserted to obtain 906-426.

[0123] The BamHI and SalI sites of pSPB176 described in the report of Ueyama et al. (Ueyama et al. Plant Science, 163, 253-263, 2002) were inserted by partial digestio...

Abstract

Disclosed is a rose characterized by containing a flavone and a delphinidin by a genetic recombination technique. Typically, the flavone and the delphinidin are produced by the expression of a flavonesynthesis enzyme gene and a flavonoid 3',5'-hydroxylase gene, respectively, both introduced into the rose. The flavone synthesis enzyme gene may be one originated from a plant belonging to the familyScrophulariaceae, such as one originated from common snapdragon (Scrophulariaceae, Antirrhinum majus) and one originated from torenia (Scrophulariaceae, Torenia hybrida). The flavonoid 3',5'-hydroxylase gene may be one originated from pansy (Viola x wittrockiana).

Description

technical field [0001] The present invention relates to a rose artificially containing flavone and delphinidin. The present invention relates to a method for changing the flower color of rose by genetically manipulating the co-pigmentation effect produced by containing flavonoids and delphinidin, especially a method for changing the flower color to blue. Background technique [0002] Flowers are the reproductive organs of plants and are necessary for the production of seeds for the next generation. In order to form a seed, pollen must attach to the pistil for fertilization. Usually pollen transport is performed by bees, insects such as butterflies, hummingbirds, and occasionally bats. The role of the petals is to lure these pollinators, and the plant manages to change color, shape, and pattern as a result. [0003] When appreciating flowers, flower color is the most important trait of flowers, so flowers of various colors have been bred through hybridization from ancient ...
