Nitrate responses of Arabidopsis<i>cho1</i>mutants
Bibliographic record
Abstract
We reported a loss-of-function of an Arabidopsis double AP2 transcription factor CHOTTO1 (CHO1) gene results in the altered responses to high concentrations of nitrate (approximately 50 mM). Nitrate up to 10 mM promotes growth of the wildtype seedling, but inhibits it under higher concentrations. The cho1 seedlings responded to nitrate up to 10 mM similarly to the wildtype, but the inhibitory effect of excess nitrate is less prominent in the mutants. This phenotype is restricted to the cotyledons, and growth of the hypocotyl and roots of the cho1 mutants is inhibited by excess nitrate. The cho1 mutations caused the upregulation of two nitrate transporter genes, AtNRT1.4 and At1g52190. Altered nitrate distribution and storage may explain the phenotypes of the cho1 mutants.

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.
