Molecular Mechanism of Silicon Response to Oat Root under Drought Stress
Bibliographic record
Abstract
There are many reports that silicon has beneficial effects on plant growth and development under abiotic stress, the molecular mechanism of silicon affecting oats under drought stress is unclear. This test variety was introduced from Canada, Sweety. Na 2 SiO 3 ·9H 2 O was used as the silicon source, and polyethylene glycol (PEG-6000) was used to simulate the drought stress environment. Normal growth as control, drought stress (25% PEG-6000), and silicon + drought stress (10 mmol/L Na 2 SiO 3 ·9H 2 O + 25% PEG-6000) on the root of oats were analyzed by transcriptome analysis (176 555 single genes) in order to compare the differential genes of plants under the three treatments. Comparative transcriptomics analysis showed that silicon plays an important role in changing the expression levels of 234 genes under drought stress. GO enrichment analysis showed that the enrichment of related genes such as oxidoreductase activity, cellular nitrogen compound metabolism, and cellular macromolecular metabolism significantly increased, and these genes are inextricably linked to abiotic resistance, indicating that silicon may induce drought tolerance in oat seedlings. By studying the mechanism of silicon-mediated drought resistance, it provides a theoretical basis for the application of silicon in crop production in arid regions.

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.
