Abstract
The Target of Rapamycin (TOR) is a conserved multifunctional Serine/ Threonine protein kinase present in all eukaryotes, which controls several important signaling pathways related to growth and development. In the present investigation, we report that TOR overexpressing Arabidopsis plants ATR-1.4.27, and ATR-3.7.32 exhibit enhanced tolerance to osmotic and salt stress treatments. The TOR overexpressing lines ATR-1.4.27, and ATR-3.7.32 treated with mannitol (100 mM), NaCl (150 mM), sorbitol (200 mM), and PEG (7% w/v), showed improved performance in root growth, fresh weight, and lateral root density. The transgenic lines also exhibited increased proline and chlorophyll contents along with the significant upregulation of stress-responsive genes compared with their corresponding treated and untreated wild-type (WT) controls. More than 90% degradation of chlorophyll-a, chlorophyll b, and total chlorophyll contents was observed in WT plants under each stress treatment, whereas the two transgenic lines had very low degradation ranging from 40% to 50%. Stress treated TOR-OE lines also showed decreased malondialdehyde (MDA) content, and high chlorophyll fluorescence of PhotosystemII (PSII; Fv/Fm ratio) compared with the treated WT control. Taken together, our results show that the constitutive overexpression of TOR enhances salt and osmotic stress tolerance in Arabidopsis thaliana.

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
