Abstract
This study combined metabolomics and genomics data to analyze the biosynthesis of theobromine in Theobroma cacao . The results show that theobromine is mainly synthesized in the young peels and cotyledons, and gradually accumulates in the seeds as the tissues mature. Metabolic pathway analysis revealed that the synthesis of theobromine is related to the transformation of purine nucleotides such as AMP and GMP, with key intermediates including 7-methylxanthosine and 3-methylxanthine. Genomic research has found that during the domestication process, genes related to theobromine metabolism were significantly selected, thereby affecting the theobromine content in different varieties. Multi-omics data also indicate that post-processing steps such as fermentation can lead to a decrease in theobromine levels. This study aims to provide molecular targets and theoretical references for improving cocoa quality and developing functional components.

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 it
