ROSE CONTAINING FLAVONE AND MALVIDIN, AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2012 - IPC C12N15/09 

FIELD: chemistry.

SUBSTANCE: disclosed is a rose whose colour changes to blue, containing a flavone synthase gene of the family Scrophulariaceae, a pansy flavonoid-3′,5′-hydroxylase gene (Viola x wittrockiana), and an anthocyanin methyltransferase gene whose amino acid sequence are given in the description, and where the rose contains: (a) flavone produced by expression of the flavone synthase gene, (b) delphinidin produced by the flavonoid-3′,5′-hydroxylase gene, and (c) malvidin produced by the anthocyanin methyltransferase gene. Described is a part, tissue, a vegetative body and a cell of the rose having the same genes. Disclosed is a method of changing the flower colour to blue, involving introduction into the rose of the flavone synthase of the family Scrophulariaceae, a pansy flavonoid-3′,5′-hydroxylase gene (Viola x wittrockiana) and an anthocyanin methyltransferase gene, and involving expression of flavone synthase, flavonoid-3′,5′-hydroxylase and anthocyanin methyltransferase genes.

EFFECT: invention enables to change the colour of petals of a rose towards blue.
