Changes of proline content and metabolism enzyme activities in wheat seedlings under Zn,Fe and Cu stresses in single or combination
Bibliographic record
Abstract
This study aims to investigate proline content and enzyme activities involved in proline metabolism in wheat(cv Ningchun 4)seedling roots exposed to Zn,Fe and Cu in single or combination.The results show that proline content increase under various heavy metal stresses,and except for Zn+Fe treatment,the increase rate of proline content under other combined treatments are high as compared with the single treatments.Root ornithine aminotransferase(OAT)activity in wheat seedlings increases compared with the control.Differently,glutamate kinase(GK)activity has no significant change under single heavy metal and Zn+Fe treatments,but the activity of this enzyme increases significantly in response to Zn+Cu,Fe+Cu and Zn+Fe+Cu treatments.Additionally,proline dehydrogenase(PDH)activity decreases under various heavy metal stresses.It can be inferred that the increase of proline content in wheat seedling roots is associated with the changes of OAT,GK and PDH activities induced by Zn,Fe and Cu treatments in single or combination.

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.
