| Outline of Final Research Achievements |
Cloning and analysis of environmental responsiveness of the genes encoding sucrose-cleaving enzymes, together with analyses of enzymatic activities and carbohydrate metabolism, were conducted in Eustoma grandiflorum, a major ornamental crop for cut flowers. As a result, one gene encoding invertase that is up-regulated in leaves under heavy-manuring condition and another gene encoding sucrose synthase that is up-regulated in petals under low-oxygen packaging were successfully identified, indicating the modification of sucrose cleavage pathway during growth, flowering and postharvest processes of the crop.
