Other claims from this paper (12)
- Observation Fructose 2,6-bisphosphate was detected in Ananas comosus.
- Observation Fructose 2,6-bisphosphate was detected in Bryophyllum tubiflorum.
- Observation Fructose 2,6-bisphosphate was detected in C3 and CAM Mesembryanthemum crystallinum.
- Observation In both Mesembryanthemum tissues, F 2,6-P(2) was outside chloroplasts.
- Association F 2,6-P(2) levels correlated with stages of the day-night CAM cycle in both Ananas and Bryophyllum.
- Observation F 2,6-P(2) rose rapidly then fell after dark-to-light transition.
- Observation F 2,6-P(2) increased later, accelerating during afternoon carbon uptake.
- Observation After light-to-dark transition, F 2,6-P(2) fluctuated and then was usually low.
- Association F 2,6-P(2) pools rose with malate synthesis, stayed high when synthesis was constant, then fell as synthesis waned.
- Observation F 2,6-P(2) levels were always higher in Ananas than Bryophyllum.
- Observation The ratio of pyrophosphate fructose-6-phosphate phosphotransferase to cytoplasmic fructose 1,6-bisphosphatase activity was far higher in Ananas.
- Observation The ratio of pyrophosphate fructose-6-phosphate phosphotransferase to phosphofructokinase activity was far higher in Ananas.
