Abstract
In rice (Oryza sativa L.) OsAMT1.1 is the most active and / or most N-responsive gene responsible for high-affinity NH4+ transport (HATS) activity. We measured 13NH4+ influx and plant biomass in transgenic overexpression lines and two wild type cultivars of rice, Jarrah and Taipei, with one or more copies of OsAMT1.1. 13NH4+ influx was higher for the overexpression lines of Jarrah line when grown at 10 µm external NH4+ concentration, but not for the overexpression lines of Taipei. For seedlings grown at 2 mm external NH4+ concentration Jarrah lines 77-1 and 75-4 showed an increased influx; however, two overexpression lines of Taipei showed reduced influx rates. The biomasses of the transgenic lines grown at low and high external NH4+ concentrations were either reduced or showed no statistically significant differences compared with wild type lines. While 13NH4+ influx into roots of Jarrah line 75-4 grown at 10 µm external NH4+ concentration was significantly higher than in wild type, measurements of 13NH efflux revealed no differences, and thus net uptake of NH4+ was higher in this overexpression line.

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
