The <i>FUS3</i> transcription factor functions through the epidermal regulator <i>TTG1</i> during embryogenesis in <i>Arabidopsis</i>
Bibliographic record
Abstract
Loss-of-function mutations in the FUSCA3 (FUS3) gene of Arabidopsis result in alterations in cotyledon identity, inability to complete late seed maturation processes, and the premature activation of apical and root embryonic meristems, which indicates that this transcription factor is an essential regulator of embryogenesis. Although FUS3 shows a complex pattern of expression in the embryo, this gene is only required in the protoderm to carry out its functions. Moreover, the epidermal morphogenesis regulator TRANSPARENT TESTA GLABRA1 (TTG1) is negatively regulated by FUS3 in the embryo. When a loss-of-function ttg1 mutation is introduced into a fus3 mutant, a number of fus3-related phenotypes are rescued, indicating a functional TTG1 gene is required to manifest the fus3 mutant phenotype. It therefore appears that one of the functions of FUS3 is to restrict the domain of expression of TTG1 during embryogenesis. The FUS3-TTG1 interaction is both maternal and zygotic, suggesting a complex relationship is required between these gene products to allow correct seed development.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
