Other claims from this paper (17)
- Observation Active polyamine metabolism occurred during imbibition.
- Observation Free Put content was about 880 nanomoles per gram dry tissue.
- Observation Free Spd content was about 920 nanomoles per gram dry tissue.
- Observation Cad and Agm levels were relatively low.
- Intervention effect GA(3) did not significantly change polyamine levels during the eight-hour lag period.
- Intervention effect Abscisic acid did not alter polyamine levels.
- Observation Ornithine and arginine were primarily incorporated into Put.
- Intervention effect GA(3) did not significantly affect incorporation into Put.
- Intervention effect GA(3) did not affect Put uptake or turnover.
- Intervention effect GA(3) did not affect Put-to-Spd or Spd-to-Spm conversion.
- Intervention effect GA(3) did not significantly change total or specific activities of two decarboxylases.
- Intervention effect MGBG substantially reduced Spd level.
- Intervention effect MGBG did not affect adenosine incorporation into ATP.
- Association Lower Spd was associated with less GA(3)-induced alpha-amylase formation.
- Intervention effect Added Spd partly or fully overcame MGBG reduction of GA(3)-induced alpha-amylase.
- Mechanism The authors infer early GA(3) action on alpha-amylase induction is not on polyamine metabolism.
- Mechanism The authors suggest polyamines, especially Spd, may regulate growth-substance-dependent enzyme induction.
