Other claims from this paper (12)
- Intervention effect SST activity in excised barley leaf blades increased 20-fold within 24 hours in the light.
- Intervention effect SST activity in barley leaf blades disappeared after transfer to the dark.
- Intervention effect Cycloheximide did not affect the loss of SST activity in the dark.
- Intervention effect No SST activity appeared in the light when photosynthesis was inhibited by lowering CO2.
- Intervention effect Sucrose induced SST activity and fructan synthesis in the dark and at low CO2.
- Intervention effect Maltose and fructose had the same effect as sucrose on SST activity and fructan synthesis.
- Intervention effect Trehalose induced SST activity in barley leaf blades.
- Intervention effect Trehalose did not lead to fructan synthesis.
- Intervention effect Fructan hydrolase and invertase activities changed little during the light/dark cycle.
- Observation Fructan was degraded in barley leaf blades after transfer to the dark.
- Observation Barley leaf blades rapidly synthesized large quantities of fructan in the light.
- Mechanism Control of SST activity together with photosynthate supply appears to regulate fructan metabolism in barley leaves.
