| Research Abstract |
Greenhouse chrysanthemum (Zinba) and diploid wild chrysanthemum (Chrysanthemum boreale) were transformed with several floral induction and circadian clock genes (CCA1, CO, FT, LKP2, TOC1). Only FT transformed plants showed in vitro flowering. The FT transformed plants repeated vegetative- and reproductive-growth. The floral induction appeared stronger in the one-node explant derived from lower positions of stock FT transformed plants, due to expression characteristics of Pmas dual promoter. Floral induction of FT transformed chrysanthemum was appeared regardless light conditions and sucrose levels in the medium.
