Abstract
八氢番茄红素脱氢酶（PDS）是影响类胡萝卜素合成的一个重要限速酶,在植物花色发育过程中起着重要作用。采用RT-PCR技术从中国水仙（Narcissustazetta var.chinensis）幼嫩花蕾中分离到一个新的水仙花色发育相关的PDS基因,命名为NTPDS1（GenBank登记号：EU138883）。该基因长1719bp,具有一个1713bp的完整开放读码框（ORF）,编码570个氨基酸。序列分析表明,NTPDS1编码的氨基酸序列与其它植物的PDS蛋白有很高的相似性。系统进化树分析显示,NTPDS1与喇叭水仙亲缘关系最近。利用半定量PCR技术进行组织表达模式分析发现,该基因在中国水仙的花、叶片和根中均有表达,但以花器官中表达量最高;在花瓣和副冠中的表达量高于雄蕊和雌蕊。

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
