Abstract
本研究以柱型苹果＂鲁加6号＂试管苗叶片外植体为转化材料,以卡那霉素抗性基因为选择标记,建立了根癌农杆菌介导的柱型苹果＂鲁加6号＂苹果的遗传转化体系。研究结果表明：在MS＋6-BA4.0mg/L＋NAA0.05mg/L培养基上,叶片不定芽分化阶段Km的选择压力为20mg/L,不定芽生根阶段Km的选择压力为15mg/L,脱菌培养阶段头孢霉素的适宜浓度为300mg/L。在农杆菌介导的遗传转化过程中,外植体经过36h预培养,侵染10min,共培养48h时,有利于提高遗传转化效率,获得的抗性愈伤组织和抗性芽数均最高。获得的Km抗性植株经PCR检测,扩增出特异条带,初步证明目的基因已整合到苹果基因组DNA中。

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.
