Stimulatory and Inhibitory Conditioning Factors that Regulate Cell Proliferation and Morphogenesis in Plant Cell Cultures.
Bibliographic record
Abstract
Proliferation and morphogenesis in plant cell cultures are influenced by the conditioning factors that are produced by the cultured cells themselves. Phytosulfokines(PSKs), sulfated peptide growth factors, have been identified as conditioning factors that promote cell proliferation in plant cell cultures. Our research has shown that the formation of carrot somatic embryos is regulated by both stimulatory and inhibitory conditioning factors. The stimulatory factor was found to be PSK, which markedly increased the frequency of somatic embryo formation. In contrast, the inhibitory factor was identified as 4-hydroxybenzyl alcohol(4HBA). 4HBA strongly inhibited somatic embryo formation by specifically suppressing the rapid cell division that is characteristic of the early globular stage. These findings suggest that dose-balancing of various plant growth regulators, including PSK and inhibitory factors, like 4HBA, might contribute to cell proliferation and morphogenesis in plant cell cultures.

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.
