Abstract
CMS／Rf测交F1结实率与花粉可育率检测表明，Ansanbyeo和南34对三种不同细胞质来源的粳稻不育系（CMS—DT1，CMS—BT和CMS—HE）都有较强的恢复力。根据已公布的水稻基因组序列，在水稻恢复基因定位区段内设计引物，确定出一对与两个滇型CMS的恢复系Ansanbyeo和南34恢复基因紧密连锁的分子标记引物M43804和M43558，首次克隆了滇型恢复基因Rf-D1（t），编码16个PPR蛋白。序列比对表明，该基因与BT型恢复基因Rf-1相似度达99％，两个恢复基因之间在ORF区仅存在一个碱基差异，即Rf-D1（t）第1149bp位的A变成Rf-1的C，并产生一个氨基酸的改编即K（赖氨酸）变成N（天冬酰胺）。该差异处于一个PPR结构域中，暗示该氨基酸是恢复基因的关键位点之一，它的改变可能影响对水稻CMS育性恢复力的变化。

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.
