Effect of Night Temperature on the Activity of Sucrose Phosphate Synthase, Acid Invertase, and Sucrose Synthase in Source and Sink Tissues of Rosa hybrida cv Golden Times.

Sucrose phosphate synthase and acid invertase activities in the mature leaves of roses (Rosa hybrida cv Golden Times) were greater in plants grown under a higher night temperature than under a lower temperature regime. In young shoots, the activity of acid invertase was promoted by the lower temperature while that of sucrose synthase was increased at the higher temperature. At both temperatures...

Light/Dark profiles of sucrose phosphate synthase, sucrose synthase, and Acid invertase in leaves of sugar beets.

The activity of sucrose phosphate synthase, sucrose synthase, and acid invertase was monitored in 1- to 2-month-old sugar beet (Beta vulgaris L.) leaves. Sugar beet leaves achieve full laminar length in 13 days. Therefore, leaves were harvested at 2-day intervals for 15 days. Sucrose phosphate synthase activity was not detectable for 6 days in the dark-grown leaves. Once activity was measurable...

Sucrose phosphate synthase and sucrose accumulation at low temperature.

The influence of growth temperature on the free sugar and sucrose phosphate synthase content and activity of spinach (Spinacia oleracea) leaf tissue was studied. When plants were grown at 25 degrees C for 3 weeks and then transferred to a constant 5 degrees C, sucrose, glucose, and fructose accumulated to high levels during a 14-d period. Predawn sugar levels increased from 14- to 20-fold over ...
