Abstract
Carbohydrate accumulation is common in frost-resistant plants, and many enzymes participate in this process. The sugar content and expression levels of metabolic enzymes related to sugar biosynthesis in response to drops in temperature were measured in two cultivars of winter wheat (Triticum aestivum) with different cold tolerances. The results indicate that the two cultivars examined, Dongnongdongmai 1 and Jimai 22, accumulated high levels of carbohydrate before November 4 (above 0°C), and that accumulation decreased as temperatures fell. However, this decrease was more modest in Dongnongdongmai 1, which had a higher sugar content. Sucrose and fructose were the main soluble sugars, indicating an important role in freezing tolerance. Gene expression studies revealed that expression of the genes encoding chloroplastic enzymes was significantly upregulated in the tillering nodes. Expression upregulation of TaSS and TaTPT may be helpful for sugar accumulation before November 4.

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
