Transgenic Nierembergia scoparia (Tall Cupflower)
The genus Nierembergia (family Solanaceae), consists of about 30 species and originated from subtropical South America (Cocucci 1991). Although they have high horticultural value, only two species, N. repens and N. hippomanica, have been horticulturally grown for cover plants or pot plants without any cultivars being bred, and in the 1990s, some cultivars were bred for the first time by a Japanese seed company. Tall cupflower (Nierembergia scoparia) used in our study is a native species of Argentina and has been recently introduced to Japan as an ornamental plant because of its beautiful pale blue flower and long flowering period.
