Abstract
含有三碳碳环的环丙烷脂肪酸（CPA．FAs）和环丙烯脂肪酸（CPE—FAs）由于具有特殊的理化性质因而在化工领域有特殊的应用。环丙烷脂肪酸合酶基因负责合成CPA—Fas，植物中尚没有这类基因启动子特征的相关报道。本研究克隆了一个棉花环丙烷脂肪酸合酶基因CPA—FAS一2的启动子区域，对该段区域进行生物信息学分析后发现其含有根、花器官以及种子特异表达元件，还含有磷（P）、硫（S）缺乏、病原菌和干旱等逆境响应元件等。通过构建该启动子序列与GUS基因融合表达载体并转化拟南芥，对T，代转基因材料染色后发现该启动子不仅具有器官表达差异性，并且还受发育时期影响。GUS基因在幼苗期并不表达，只在植株成熟期表达，并且表达部位只限于茎基部、根、种子以及花药。进一步利用GUS定量，结果表明该启动子受P缺失以及干旱胁迫的诱导。本研究进一步明确了环丙烷脂肪酸合酶基因的表达特征，有利于促进该基因在种质创新中的利用。

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.
