Changes in polyamine contents and arginine decarboxylase activity associated with elongation growth of hypocotyls in<i>Rhizophora apiculata</i>Bl.
Bibliographic record
Abstract
Changes in polyamine (putrescine, spermidine, spermine) contents and arginine decarboxylase activity in three different regions of developing hypocotyls of Rhizophora apiculata Bl. were analyzed. Among the three polyamines, spermidine was present in higher quantities than either putrescine or spermine. Spermine occurred in the lowest quantities. Spermidine declined rapidly with the age of the hypocotyl. In contrast, a marked increase in putrescine was observed with the age of the hypocotyl. Arginine decarboxylase activity increased during the various developmental stages of hypocotyl growth, particularly in the final stage. The results suggest that putrescine plays a major role in the growth of the hypocotyl as evidenced by simultaneous increase in the content of putrescine and arginine decarboxylase activity.Key words: arginine decarboxylase, elongation, hypocotyls, polyamines, Rhizophora apiculata.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
