Definitions
- the present invention relates to a method for producing para having a new flower color. Specifically, a gene that artificially suppresses para endogenous metabolic pathways, and that encodes a flavonoid 35 light, monohydroxylase, and dihydromyricetin, which reduces pancreatic flavonoids.
- the present invention relates to a method for producing roses by expressing a gene encoding flavonol reductase.
- the current yellow paras were bred by crossing Rosa foeti da native to West Asia with paras that did not have the yellow variety.
- the color of flowers is determined by the genetic ability of the plant, and there is a limit to the flower color that can be achieved by breeding by crossing, which has limited available gene sources (Tanaka et al. Plant Cell Physiol. 39 1119-1126, 1998, Mol et al. Curr. Opinion Biotechnol. 10, 198-201 1999). Above all, it is said that it is impossible to cultivate a blue para, but it has been considered a synonym for King Arthur's Holy Grail. 1990 Kodansha Blue Pax, Saizuki Aizuki "Blue Para" 2001 Shogakkan).
- blue para refers to “mauve” para. It is said that the first breeding of “Blue Para” by mating is “Gray Pearl”, a gray with light purple color, created in 1945. Later, in 1957, light purple pink “Sterling Silver” was produced, and many varieties of these varieties, such as “Bloom-In” (created in 1964) and “Madam Biore” (created in 1981), were used as mating parents. A color para is being made. By using these mauve-type paras and breeding more, pale gray paras such as Seiryu (created in 1992) and Blue Heaven (created in 2002) are created. It is attracting attention as a new type of “blue para.”
- the color of these flowers is not actually blue, but rather a greyish, crisp pink, and despite years of breeding efforts, there is still no para to be called “blue”.
- the Royal Horticulture Society Color Chart generally refers to the group of palaces, villas and benorays as “blue”.
- the present invention aims at the creation of paras having flower colors indicated by the Pirate Group, the Pirates Toble Group or the Blue Group at the Royal Horticultural Society Power Ratchato.
- the color of the flower is mainly derived from three kinds of compounds, anthocyanins, carotenoids and betalains, but the blue color has the maximum absorption wavelength range.
- Anthocyanin is a type of flavonoid and is biosynthesized by the metabolic pathway shown in Fig. 1.
- Antosyanin is normally located in the vacuoles of epithelial cells.
- the color of anthocyanin ie, the color of the flower greatly depends on the structure of anthocyanin, and the more the number of hydroxyl groups in the B ring, the more blue.
- Ring B hydroxylation is catalyzed by flavonoid 3'-hydroxylase (F3'H) and flavonoid 3 ', 5'-hydroxylase (F3'5'H). If there is no F3'H activity and no F3'5'H activity, pelargidine (orange to red) is synthesized, and if there is F3'H activity, cyanidin (red to red) is synthesized, and F3'5 If there is' H activity, delphinidin (purple) is synthesized.
- flavonoid 3'-hydroxylase F3'H
- flavonoid 3 ', 5'-hydroxylase F3'5'H
- anthocyanidins are modified with sugars and acyl groups to produce various anthocyanins.
- the more aromatic acyl groups to modify the bluer the anthocyanin.
- Anthocyanin changes its color significantly depending on the vacuolar pH, coexisting flavonol-flavones, metal ions, etc. (Norio Saito Protein Nucleic Acid Enzyme 47 202-209 2002, Broullard and Dangles, In the flavonoids: Advances in Research since ⁇ 986 (Ed by Harborne) Capmann and Hall, London pp5b5-588, Tan aka et al. Plant Cell Physiol. 39 1119-1126, 1998, Mol et al, Trends in Plant Science 3, 212-217 1998, Mol et al. Curr. Opinion Biotechnol. 10, 198-201 1999).
- Parapetal anthocyanin is a derivative of peranolegonidin, a derivative of cyanidin and zeonidine, and no derivative of delphinidin (Biolley and May, J. Experimental Botany, 44, 1725-1734).
