Bibliographic record
Abstract
Abstract Ocimum sanctum is a multipurpose herb with highly significant medicinal properties. An in vitro direct regeneration protocol for propagation of a valuable medicinal plant Ocimum sanctum , using petiole explants has been successfully developed. The protocol employed regeneration of shoots directly, without any intervening callus using Murashige and Skoog (MS) medium fortified with 3 mg L -1 BAP + 1 mg L -1 NAA. The maximum regeneration frequency of 98% with 9.6 shoots per explants was achieved. Agrobacterium tumefaciens mediated genetic transformation (ATMT) protocol (transient and stable) was established using LBA4404 strain harboring pBI121 with uid-A reporter gene and neomycin phosphotransferase ( npt-II ) as selection marker. The putative transformants were screened on MS with 50 mg L -1 kanamycin and subsequently rooted on the half-strength MS medium. The confirmation was done via polymerase chain reaction (PCR) using npt-II and gus-A gene-specific primers. The maximum stable transformation frequency 70% ± 0.35. Thus, it is apparent that the established in vitro direct regeneration and ATMT method was suitable for integrating novel genes and modulating the metabolic flux for obtaining desired agronomic trait in planta .

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.
