Isolation and Characterization of plant TAF9, an Orthologous Gene for TATA Binding Protein Associated Factor 9, from Wintersweet (Chimonanthus praecox)
Bibliographic record
Abstract
TAF9 is one of the TATA-binding protein-associated factors (TAFs) that constitute the TFIID complex. We isolated a plant TAF9 ortholog from the Chimonanthus praecox (L.) Link cDNA library and named it CpTAF9. The CpTAF9 protein contained the conserved TAF9 and H2A superfamily domain, which is highly conserved among the TAF9s of other organisms. It also showed a specific tissue expression pattern that the transcript level of CpTAF9 was higher in mature leaves than in other tissues. In addition, CpTAF9 expression in wintersweet leaves could be induced by treatment with salt or high temperatures, or by exogenous abscisic acid application. Overexpression of CpTAF9 in Arabidopsis thaliana (L.) Heynh. under the cauliflower mosaic virus 35S promoter improved salt and high-temperature stress tolerance to some extent. These results demonstrated that CpTAF9 may have a role in gene regulation associated with salt and heat stress responses in wintersweet, providing a foundation for further elucidating the molecular mechanisms that underlined TAF-mediated control of the stress response processes in plant.

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.
