Constitutive expression of chrysanthemum <i>CmBBX29</i> delays flowering time in transgenic <i>Arabidopsis</i>
Bibliographic record
Abstract
BBX transcription factors are known to regulate the flowering time and the plant response to various abiotic stresses, but their functions in chrysanthemum have yet to be thoroughly explored. Here, a chrysanthemum homolog of the Arabidopsis thaliana gene AtBBX29 was isolated and characterized. The gene was transcribed in various plant organs but most strongly in the root and in the ligulate flowers. Its temporal pattern of transcription mirrored that of CmCO, the chrysanthemum homolog of the key flowering regulator CONSTANS (CO). Its constitutive expression in A. thaliana induced a delay to flowering, suppressing the transcription of FLOWERING LOCUS T (FT), SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 (SOC1), LEAFY (LFY), and APETALA 1 (AP1), while promoting that of FLOWERING LOCUS C (FLC). Our results indicate that CmBBX29 can regulate flowering time in A. thaliana by the integration of FLC and the photoperiod pathway.

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.
