Abstract
依赖焦磷酸的磷酸果糖激酶（PFK）是糖酵解途径的关键酶。本研究首先构建带有种子特异性napin启动子和Nos终止子的植物表达载体2300-nap及带有组成型35S启动子和Nos终止子的植物表达载体2300-35S；然后用PCR法从甘蓝型油菜（Brassica napus L．）中油119总基因组中扩增出依赖焦磷酸的磷酸果糖激酶（PFK）基因片段，再以扩增出的PFK基因片段作模板设计引物扩增出一个相应的小片段。将两个PFK基因片段反向连接，插入到植物表达载体2300-nap的napin启动子和nos终止子之间，植物表达载体2300-35S的35S启动子和nos终止子之间，分别构建成可转录表达出发夹RNA（hairpin RNA，hpRNA）结构的种子特异型和组成型油菜RNA干扰载体，为今后油菜利用RNA干扰（RNAi）提高含油量的基因工程研究奠定了基础。

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.
