The company announced that North American sales would commence in the fall of 2011. Prices were from 2,000 to 3,000 Yen or US$22 to $35 a stem. Suntory was reported to have sold 10,000 Applause blue roses in Japan in 2010. Īs of 2008, the GM roses were being grown in test batches at the Martino Cassanova seed institution in South Hampshire, according to company spokesman Atsuhito Osaka. Further deepening the blue colour would therefore require further modifications, by traditional breeding or further genetic engineering, to make the rose less acidic. Additionally, rose petals are more acidic than pansy petals, and the pansy delphinidin in the transgenic roses is degraded by the acidity in the rose petals. However, the RNAi did not completely knock out the activity of DFR, so the resulting flower still made some of its natural color, and so was a red-tinged blue – a mauve or lavender. If the strategy worked perfectly, in theory it could produce a truly blue rose. The researchers then used RNA interference (RNAi) technology to depress all other color production by endogenous genes by blocking a crucial protein in color production, called dihydroflavonol 4-reductase (DFR), and adding a variant of that protein that would not be blocked by the RNAi but that would allow the color of the delphinidin to show. First, the researchers inserted a gene for the blue plant pigment delphinidin cloned from the pansy into a purplish-red Old Garden rose "Cardinal de Richelieu", resulting in a dark burgundy rose. The genetic engineering involved three alterations - adding two genes, and interfering with another. The company and press have described it as a blue rose, but it is lavender or pale mauve in color.
Scientists have yet to produce a truly blue colored rose however, after thirteen years of collaborative research by an Australian company, Florigene, and a Japanese company, Suntory, a rose containing the blue pigment delphinidin was created in 2004 by genetic engineering of a white rose.
