Effect of Seed Soaking with Spermidine on Contents of Polyamines Conjugated to the Deoxyribonucleic Acid-protein in Maize(Zea mays L.) Seedling Roots under Osmotic Stress
Bibliographic record
Abstract
The contents of noncovalently conjugated polyamines(NCC-PAs) to deoxyribonucleic acid-protein(DNP) isolated from maize(Zea mays L.) seedling roots under osmotic stress were detected by HPLC.Results showed that after osmotic stress treatment for 7 d,the levels in NCC-spermidine(NCC-Spd) and NCC-spermine(NCC-Spm) of drought-tolerant Nongda 108 cv.increased more markedly than that of drought-sensitive Yedan 13 cv.,while the NCC-putrescine(NCC-Put) couldn't be statistically detected in two cultivars.Treatment of seed-soaking with Spd alleviated osmotic stress injury to Yedan 13 cv.seedlings,coupled with marked increases of NCC-Spd and NCC-Spm levels of this cultivar.These results suggested that Spd seed-soaking could enhance the tolerance of maize seedlings,especially of the drought-sensitive cultivar,to osmotic stress,via increasing NCC-Spd and NCC-Spm in DNP of roots.

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.
