Abstract
Isoflavonoids are a diverse group of biologically active natural products that accumulate in soybean seeds during development. The majority of isoflavonoids are accumulated in the form of their glyco- and malonyl-conjugates in soybean seeds. The conjugation step confers stability and solubility to isoflavone aglycones enabling their compartmentalization to vacuoles or transport to the site of accumulation. A functional genomic approach was used to identify isoflavonoid specific glycosyltransferase (UGT) and malonyltransferase (MT) from soybean (Glycine max) seeds. An expressed sequence tag database for soybean was searched by key words to make a list of candidate genes. The full-length cDNAs for candidate UGTs and MTs were obtained and cloned into an expression vector for the production of recombinant enzymes. The in vitro enzymatic activity assays were conducted for recombinant UGTs and MTs using uridine diphosphate glucose and malonyl CoA, respectively, as donors with isoflavone substrates. Among several recombinant enzymes, UGT73F2 showed glycosylation activity towards all three soybean isoflavone aglycones and GmMT7 exhibited malonylation activity towards isoflavone glycosides. The subcellular localization study revealed both UGT73F2 and GmMT7 to be in the cytoplasm. The transcripts and protein accumulation patterns for UGT73F2 and GmMT7 genes have provided further support for their in planta function.

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
