Metabolic Network Reprogramming During Leaf Senescence in Arabidopsis
Bibliographic record
Abstract
This study collates the changes in primary metabolism of Arabidopsis thaliana during leaf senescence, from being dominated by “accumulation” to being dominated by “decomposition and reuse”, and introduces the degradation of starch, the decomposition of proteins and membrane lipids, as well as the significant roles of amino acid and polyamine metabolism in nutrient mobilization and energy supply. The functions of the phenylpropane pathway, flavonoids and other secondary metabolites in antioxidation and stress response were summarized. How transcription factors such as NAC, WRKY and bZIP, as well as hormone signals such as ethylene, ABA, JA and SA, together form a multi-level regulatory network was discussed. Moreover, through multi-omics and systems biology methods, the metabolic network and gene regulatory network related to aging were integrated and reconstructed. This study aims to construct a more systematic framework for regulating leaf senescence metabolism, providing a reference for a deeper understanding of senescence mechanisms and genetic improvement of crops.

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.
