Water-Soluble Carbon Nanotube Enhances Gossypol Production in Cotton Cell Suspension Culture
Bibliographic record
Abstract
Plant secondary metabolites are well-recognized medicinally important compounds. Gossypol is an important plant secondary metabolite with several medicinal properties. Carbon nanotubes (CNTs) are allotropes of carbon with diverse applicability in chemical, physical, and biological sciences due to their high surface area. The current study demonstrates the enhancement of gossypol production in cotton cell suspension culture in culture media supplemented with water-soluble carbon nanotubes. The fresh and dry weights of cotton cell suspension culture grown in MS media with 20 µg/mL CNTs were, respectively, 1.9 and 2.13 fold higher than in control MS media after one month. The net enhancement of gossypol production in MS media supplemented with 20 µg/mL CNTs was 2.47 fold higher than the control. Confocal and SEM imaging showed the presence CNTs on the cell surface, which mediated the formation of extra channels that resulted in high biomass production in cotton cell suspension culture. The gossypol produced by this cell suspension culture showed antiproliferative activity against the prostate cancer cell line. Thus, this study demonstrated a new method for enhanced gossypol production, which can prove beneficial for the production of other plant-based biological active compounds.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
