Abstract

fetched live from OpenAlex

Ginkgo biloba L. leaves are a flavonoid resource for the pharmaceutical industry. The flavonoid 3′-hydroxylase (F3′H) is a key enzyme in the flavonoid biosynthesis pathway. However, the role of F3′H in flavonoid biosynthesis and metabolism is unclear. In this study, we characterized and functionally analyzed the ginkgo F3′H gene GbF3′H1 that encodes a protein of 520 amino acids. Expression profiling showed that GbF3′H1 was highly expressed in the leaves of ginkgo in September. Subcellular localization showed that GbF3′H1 occurred predominately in the cytoplasm. Transgenic poplars overexpressing GbF3′H1 had more red pigmentation in leaves than did wild-type (WT) plants. Furthermore, the concentrations of epigallocatechin, gallocatechin, and catechin in the downstream products synthesized by flavonoids were significantly higher in the transgenic plants than in the WT plants. These results indicate that the overexpression of GbF3′H1 enhances flavonoid production in transgenic plants and provides new insights into flavonoid biosynthesis and metabolism.

Teacher imitation

Not 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.
