Abstract
甘蓝型油菜细胞核雄性不育是杂种优势利用的重要途径。隐性上位互作核不育系9012A已经广泛用于杂交种子生产,其不育性受两对隐性重叠不育基因（ms1和ms2）与一对隐性上位抑制基因（rf）互作控制。ms1和ms2同时纯合（ms1ms1ms2ms2）表现不育,但隐性纯合rf（rfrf）对ms1ms1ms2ms2的表达起抑制作用,又可使其表现可育（TAM系,ms1ms1ms2ms2rfrf）。本研究利用AFLP和SRAP分子标记技术,分别筛选了884对AFLP引物和506对SRAP引物,筛选到了14个与不育基因Ms1基因紧密连锁的标记,其中4个标记与育性共分离。Ke等发表的AFLP标记E-ACA/P-CTG在本研究群体中与Ms1基因相距0.1cM。紧密连锁标记测序序列BLASTN结果表明,其和拟南芥第五染色体高度同源,并且通过和已测序的甘蓝C基因组序列进行比对,将其定位在C9染色体的末端。本研究结果有助于该基因的分子标记辅助选择和克隆。本文还对前人发表的与Ms1基因连锁的标记在本研究群体中的分离情况作了探讨。

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.
