Abstract
斑茅是甘蔗近缘野生种之一,具有较强的抗逆性,研究并开发利用斑茅的强抗逆基因,对甘蔗育种具有重要意义。本研究以高粱Cu/Zn-SOD(登录号:XM 002445626.1)cDNA序列为探针,对甘蔗属EST数据库进行检索、比对、拼接,通过设计特异引物,PCR扩增和序列分析验证,克隆得到2个Cu/Zn-SOD(SaSOD-1a和SaSOD-1b,登录号:KJ001795和KJ001796)基因全序列,其中SaSOD-1a基因组序列全长2 473 bp,SaSOD-1b基因组序列全长2 228 bp,均有8个外显子,7个内含子,其cDNA序列长度均为692 bp,编码206个氨基酸。序列比较分析表明,SaSOD-1a和SaSOD-1b序列相似性为98.6%,有8个单核苷酸多态性位点,蛋白质相似性为99.0%,2个氨基酸变异位点。用推导出的氨基酸序列与其它植物做同源进化分析,与高粱、玉米、谷子等比较均表现出较高的保守性。研究结果可为进一步了解超氧化物歧化酶与斑茅耐旱性的关系奠定基础。

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.
