> Suntory began its blue rose research in 1990. Roses naturally lack a key gene required to produce delphinidin, the blue pigment found in many blue flowers. In 2004, Suntory Group became the first in the world to develop roses that accumulate delphinidin by introducing a gene that enables roses to produce this pigment. This achievement led to the launch of SUNTORY blue rose APPLAUSE in 2009. Since then, SIC has continued its research toward even bluer roses by exploring the various mechanisms that create blue flower colors in nature.
> In this study, the researchers explored a new approach to achieving bluer flower colors by focusing on the effect of copigmentation.
That would be akin to: Linux 7.2 released (1991)
