Differences in cellular structure regulate stem elongation of alpine and prairie ecotypes of<i>Stellaria longipes</i>grown under two contrasting temperature regimes
Bibliographic record
Abstract
The objectives of this study were to explore differences in the structural features of stem elongation in alpine and prairie ecotypes of Stellaria longipes Goldie in response to two contrasting temperature regimes. The two ecotypes were grown under warmer, 28 °C (day) – 22 °C (night), and cooler, 10 °C (day) – 4 °C (night) temperatures, and under the same light irradiance (∼120 µmol·m–2·s–1) and photoperiod (16 h). Temperature exerts a significant effect on the stem elongation of alpine and prairie ecotypes of S. longipes. Significant retardation of growth occurred in plants grown in cooler temperatures (10 °C (day) – 4 °C (night)), while growth was profoundly enhanced when plants were grown under warmer conditions (28 °C (day) – 22 °C (night)). The ecotypes exhibited differential responses to temperature (owing to differences in their cellular structure), particularly in cell length, the timing of cell wall thickening, the deposition of phenolic compounds, and the changes in cortical microtubule orientation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
