Abstract
Objective To clone the full-length cDNA of the uridine diphosphate glycosyltransferase(UGT) gene in Bupleurum chinense(BcUGT8),which may be involved with the saikosaponin biosynthesis,and to construct the prokaryotic expression vector.The work will provide the foundation for its further function verification by in vitro expression and activity analysis of the purified protein.Methods RACE and LD-PCR were used to clone the full-length cDNA of BcUGT8,on the basis of its partial cDNA sequence obtained from our previous high-flux sequencing by Roche(454) GS FLX system.The open reading form(ORF) was PCR cloned using primers with corresponding restriction enzymes cutting sites.The PCR products were digested with corresponding restriction enzymes and then were inserted in expression vector pET-28a(+) to construct the recombinant expression vectors.Results The full-length cDNA of UGT gene was cloned from B.chinense,and the prokaryotic expression vector was obtained.Conclusion The full-length cDNA cloning,sequence analysis,and prokaryotic expression vector construction provide a substantial foundation for follow-up bio-function analysis of BcUGT8 through protein expression,purification,and activity analysis in vitro.

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 it
