Molecular analysis of genes related to phenylpropanoid and ascorbate biosynthesis in salt and UV-B treated pak choi grown under LEDs
Bibliographic record
Abstract
In this study, we measured the expression of genes related to the phenylpropanoid pathway and ascorbate oxidation by qRT-PCR to explore the mechanism of nutraceutical compounds enhancement in pak choi during stress treatments. The expression of most phenylpropanoid biosynthesis related genes (PAL, C4H, CHS, CHI, F3H1, DFR, and ANS1) was up-regulated in plants treated with NaCl, solar salt, and UV-B radiation, compared with the untreated controls under both white light and light emitting diode illumination. Moreover, CHS and ANS1 were expressed at levels 15 and 95 times higher than the untreated control. The expression of the ascorbate oxidation related gene tAPX was also up-regulated in the NaCl and UV-B treated samples compared with the control under both light conditions. By comparison, the expression of APX1 was down-regulated during the stress treatment under both light conditions. Total chlorophyll and total carotenoid contents were unaffected by the stress treatments, and there was no significant difference in the maximum quantum yield (F v /F m ) between the stress treatments and the untreated controls. These results suggest that the expression of genes involved in phenylpropanoid biosynthesis and ascorbate oxidation correlates with the previously reported enhanced production of phenolic compounds in pak choi plants subjected to stress treatments.

How this classification was reachedexpand
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.
