Abstract

fetched live from OpenAlex

我们在明恢86的转基因后代中发现了一个水稻花器官发育突变体,暂命名为开颖不育(open hull sterile 1,ohs1(t))突变体。ohs1(t)突变体表现颖花开裂,内外稃片变细,内稃微弯向外稃,有雌雄蕊分化,但雌雄蕊较野生型株的小,大多数花药没有花粉,少数花药中含有不育花粉,雌雄配子均不育。突变体ohs 1(t)分别与明恢86、R527、93-11和中花16号杂交后代遗传分析表明,ohs 1(t)是一个隐性基因控制的突变体。以ohs 1(t)和93-11杂交F2群体中突变个体作为初步定位群体,采用已报道的SSR标记将OHS1(t)初步定位在1号染色体的长臂端RM493和RM5638两个标记间。随后利用已公布的水稻基因组序列(http://rgp.dna.affrc.go.ip/E/index.html)及93-11和日本晴间SSR标记数据库(http://www.gramene.org/),新开发和筛选了SSR和InDel标记,并以ohs1(t)和中花16号杂交F2群体中突变个体作为新定位群体,将OHS1(t)基因进一步定位在NSSR0115和InDe10102之间,遗传距离分别为0.2cM和0.3cM,物理距离约66kb。

Not 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.
