Abstract
开花抑制基因FLC（FLOWERING LOCUS C）是春化作用中的关键基因,是控制开花时间的枢纽。本研究采用RT-PCR方法,以柱型苹果杂交后代群体中早花株系为试验材料,克隆得到柱型苹果花发育相关基因Md FLC。结果显示,Md FLC开放阅读框长度为603 bp,编码201个氨基酸,推测蛋白质分子量为47.68 k D,等电点为5.18;Md FLC蛋白二级结构包含9个α-螺旋,2个β-折叠区和12个β-转角,具有MADS典型的结构域。系统进化树分析表明,Md FLC与沙梨FLC进化关系最近,与豌豆的亲缘关系最远。半定量PCR及荧光定量PCR分析结果表明,Md FLC基因在普通型苹果‘富士’及柱型苹果株系（95-31,95-41,95-45,95-107,95-152）的花芽和花不同部位（花瓣,花蕊,花萼,花托）均有表达,在柱型苹果花芽、花瓣、花蕊、花萼及花托中的表达量均低于在富士苹果中对应部位的表达量,在花芽中的表达差异尤为显著,暗示了Md FLC基因参与了柱型苹果花芽分化以及开花进程。

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; a candidate call from one teacher head, not a consensus.
