Blue Rose is also a
fantasy
role-playing game published
in 2004 by
Green Ronin Publishing,
emulating the "romantic fantasy"
fiction sub-genre.
A blue rose.
Since
roses lack a gene to produce
delphinidin, the primary
plant pigment that produces
true blue flowers, blue roses
were traditionally created by
dyeing white roses. However, after
15 years of joint research by an
Australian company
Florigene, and Japanese
company
Suntory, a blue rose
was created in
2004 using
genetic engineering. The
delphinidin gene was cloned from
the
petunia and inserted into a
mauve-blend rose, the Old Garden
Rose 'Cardinal de Richelieu.' (a
Rosa gallica) However,
since the pigment
cyanidin was still present,
the rose was more dark burgundy
than true blue. Further work on
the rose using
RNAi technology to depress the
production of cyanidin produced a
very dark mauve plant, with only
trace amounts of cyanidin.
Blue roses traditionally
signify mystery. This symbolism
derives from the rose's meaning in
the
language of flowers common in
Victorian times.
