| Research Abstract |
Chimeric gene that induced cytokinin biosynthesis regulating gene IPT under the control of senescence activated promoter PSARK (PSARK-IPT) was introduced into floricultural plants such as petunia and chrysanthemum and their shelf-life were observed. As results, in 'Seikonomakoto' chrysanthemum which has a problem of leaf-yellowing during storage and transportation, cut flowers harvested from PSARK-IPT introduced trangenic plants showed markedly delayed leaf-yellowing. They also showed delayed leaf-senescence even under dark condition and ethylene exposure. These results provide valuable information for breeding floricultural plants with stress-tolerance and long-self life that would lead to low cost, energy saving and economical transportation.
