MONOPTEROS directly activates the auxin-inducible promoter of the Dof5.8 transcription factor gene in Arabidopsis thaliana leaf provascular cells
Bibliographic record
Abstract
MONOPTEROS (MP) is an auxin-responsive transcription factor that is required for primary root formation and vascular development, whereas Dof5.8 is a Dof-class transcription factor whose gene is expressed in embryos as well as the pre- and procambial cells in the leaf primordium in Arabidopsis thaliana. In this study, it is shown that MP directly activates the Dof5.8 promoter. Although no apparent phenotype of the single dof5.8 mutants was found, phenotypic analysis with the mp dof5.8 double mutants revealed that mutations within Dof5.8 enhanced the phenotype of a weak allele of mp, with an increase in the penetrance of the 'rootless' phenotype and a reduction in the number of cotyledons. Furthermore, interestingly, although mp mutants showed reduced vascular pattern complexity in cotyledons, the mp dof5.8 double mutants displayed both more simplex and more complex vascular patterns in individual cotyledons. These results imply that the product of Dof5.8 whose expression is regulated by MP at least in part might be involved in multiple processes controlled by MP.

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.
