A proposed role for the anaerobic pathway during low‐temperature sweetening in tubers of <i>Solanum tuberosum</i>
Bibliographic record
Abstract
Following exposure to low temperatures (i.e. < 9–10°C), tubers of potato ( Solanum tuberosum ) undergo a phenomenon known as low‐temperature sweetening (LTS), which results in the conversion of starch to sugars. LTS in stored potato tubers was evaluated by monitoring glycolysis, the oxidative pentose phosphate pathway, anaerobic respiration and mitochondrial respiration, in order to obtain an overview of the regulation of sugar metabolism during LTS. Carbohydrate metabolism during 4°C storage was evaluated in four different storage seasons, comparing tubers of cold‐tolerant (low sugar‐accumulating) clones (ND 860‐2, V 0056‐1 and Wis 1355‐1) and cold‐sensitive (high sugar‐accumulating) cultivars (Novachip and Monona). Parameters measured included whole tuber respiration, concentrations of sucrose, reducing sugars, ATP, NADH, NADPH, lactate and ethanol, as well as tissue pH. In three of the four seasons of study, the cold‐tolerant tubers maintained lower levels of reducing sugars, and higher levels of lactate and ethanol, relative to cold‐sensitive tubers. A higher anaerobic flux in tubers of cold‐tolerant genotypes may be partially responsible for a lower accumulation of reducing sugars relative to cold‐sensitive tubers. This study represents the first known report on the role of the anaerobic pathway during LTS in potato tubers.

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.
