ABI3 expression ceases following, but not during, germination of tomato and Arabidopsis seeds
Bibliographic record
Abstract
In many plant species, including tomato and Arabidopsis, the inception of dormancy during seed development is mediated by abscisic acid (ABA) and the transcription factor ABSCISIC ACID INSENSITIVE3/VIVIPAROUS1 (ABI3/VP1). Consequently, seeds carrying mutations in this gene germinate precociously. The ABI3 orthologue isolated from tomato (LeABI3) is a single copy gene expressed only in seeds. ABI3 expression ceases following the completion of germination in both tomato and Arabidopsis seeds, suggesting that expression of this gene does not regulate germination. LeABI3 expression in tomato wild-type embryos, while present in intact seeds, is greater than in their isolated embryo axes. Decreased LeABI3 expression does not occur in isolated axes from the gibberellin (GA)-deficient gib-1 mutant of tomato, in contrast to embryos from the intact seeds. This is indicative of a signal passing from the endosperm to the embryo which acts to promote LeABI3 expression in the latter, and that this signal is GA or GA-derived.

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.
