Abstract
高盐对作物造成渗透胁迫和离子毒害,是影响作物生长发育的主要非生物胁迫因子之一。Na^＋/H^＋逆向转运蛋白能够通过将Na^＋排出细胞或将其区隔化入液泡中来调节细胞内的离子平衡,是植物耐盐的关键因子。本研究将质膜Na^＋/H^＋逆向转运蛋白基因nhaA构建到植物表达载体pBI121上,通过发根农杆菌介导转化大豆子叶节,获得6株卡那霉素抗性再生植株。对抗性植株进行PCR、Southern blot和RT-PCR鉴定,3株植株呈阳性,平均转化率为0.42%。对阳性植株的耐盐生理指标测定结果显示,盐胁迫后转基因植株的质膜相对电导率显著低于对照植株,叶绿素含量和脯氨酸含量显著高于对照植株。nhaA基因在大豆植株中的表达显著提高了大豆对盐胁迫的耐受性,为大豆耐盐新品种的选育和广泛应用该基因进行其它农作物的耐盐性改良提供了材料和依据。

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.
