An ABI3-interactor of conifers responds to multiple hormones
Bibliographic record
Abstract
CnAIP2 (Callitropsis nootkatensis ABI3-Interacting Protein 2) was previously identified as a protein that interacts with the yellow-cedar ABI3 protein. CnAIP2 plays important roles during several key transitions of the plant lifecycle and acts as a global regulator with functions opposite to those of ABI3 proteins. Here we report that the CnAIP2 gene promoter is strongly upregulated by all of the major plant hormones. Young Arabidopsis seedlings expressing a chimeric CnAIP2pro-GUS construct were subjected to exogenously applied hormones; the maximum fold-enhancement of GUS activity was as high as 47-fold, and each hormone showed a distinctive cell/tissue-specific pattern of GUS induction. By far the greatest response was elicited by the synthetic auxin 2,4-D (47-fold induction); the other hormones tested stimulated GUS activities by 8- to 21-fold. The CnAIP2 promoter also responded to glucose and salt (NaCl), albeit to a lesser extent (2- to 3-fold induction). As well as acting in an antagonistic way to the global regulator ABI3, CnAIP2 appears to participate in multiple hormonal crosstalk pathways to carry out its functions.

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.
