Abstract
For proper development of plants auxin levels need to be tightly controlled. For this, several routes have evolved and it is plausible that different organisms use these differently. To determine whether members of the family of GH3 proteins, which partially act as auxin conjugate synthetases in Arabidopsis thaliana, have similar roles in the moss Physcomitrella patens, we have investigated the in vitro activity of the two GH3 members in moss. We showed that both proteins can form amino acid conjugates with indole-3-acetic acid (IAA) but also with jasmonic acid (JA). Confirming these findings, single and double knockout-mutants showed lower levels of IAA conjugates than wild type. We discuss the results in light of the possible functions of IAA conjugate formation in lower land plants.

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
