Abstract
中国水仙有金盏银盘和玉玲珑两个品种,玉玲珑由于雄蕊瓣化而形成重瓣花,而目前人们对这种重瓣花的分子机理不清楚。根据重瓣花多与C类花器官特性基因相关,本文通过RT-PCR方法分别克隆和分析了两种花型水仙品中的AGAMOUS同源基因NTAG1基因,序列分析表明,两种水仙中该基因序列完全相同,RT-PCR半定量分析它们的表达模式也相同,都仅在花器官中表达。将NTAG1基因在拟南芥中过量表达,转基因植物T0代和T1代有C类基因过量表达的类似表型,叶片卷曲、植株矮小,开花提前,少数转化子萼片、雄蕊等花器官发育异常,T3代纯合子稳定遗传的表型中不再有花器官发育异常,但植株矮小、叶片卷曲,开花提前,侧枝增多,植物提前进入衰亡期。文中对NTAG1基因在基因工程应用方面的改进进行了探讨。

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.
