General Information

General Information Comment Organism
physiological function in sugar-starved cells, the in situ activity of both sucrose synthase and invertase decrease significantly. Following supplementation of root meristems with sugar, invertase remaines inactive, but sucrose synthase activity increases. In sugar-starved cells, sucrose synthase activity is induced more by exogenous sucrose than by glucose. The sucrose-induced activity is strongly inhibited by okadaic acid and less by 6-dimethylaminopurine at early stages of regeneration, but not at the stages preceding DNA replication or mitotic activities. Prolongation of regeneration and a marked decrease in the number of cells resuming proliferation and resulting from the action of inhibitors, are correlated with the process of sucrose synthase activation at the beginning of regeneration from sugar starvation Vicia faba
