Functional Characterization of a Putative Nitrate Transporter Gene Promoter from Rice
Bibliographic record
Abstract
Drought is one of the most significant abiotic stresses that influence plant growth and development. Expression analysis revealed that OsNRT1.3, a putative nitrate transporter gene in rice, was induced by drought. To confirm if the OsNRT1.3 promoter can respond to drought stress, a 2019 bp upstream sequence of OsNRT1.3 was cloned. Three OsNRT1.3 promoter fragments were generated by 5'-deletion, and fused to the beta-glucuronidase (GUS) gene. The chimeric genes were introduced into rice plants. NRT2019::GUS, NRT1196::GUS and NRT719::GUS showed similar expression patterns in seeds, roots, leaves and flowers in all transgenic rice, and GUS activity conferred by different OsNRT1.3 promoter fragments was significantly upregulated by drought stress, indicating that OsNRT1.3 promoter responds to drought stress and the 719 bp upstream sequence of OsNRT1.3 contains the drought response elements.

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.
