Abstract
籽粒硬度是小麦品质改良的重要目标性状之一,主要由5D短臂上的Hardness（Ha）位点的两个主效基因,即Puroindoline a（Pina-D1）和Puroindoline b（Pinb-D1）控制,同时受基因Grain Softness Protein-1（Gsp-1）的影响。本研究以一粒小麦（T.monococcum）DV92作为Pina^m、Pinb^m和Gsp^m基因的供体,将三基因各自完整的表达盒串联连接到载体pGEM-TEasy上,构建Pina^m-Pinb^m-Gsp^m三基因串联的表达载体。利用基因枪介导的转化方法转化普通小麦科农199幼胚,共轰击5608个小麦幼胚愈伤,经Biolaphos（化学除草剂）筛选,获得933株再生植株,经PCR检测,鉴定出11株阳性植株,有关转基因小麦的籽粒硬度还需进一步实验验证;本实验实现了串联三基因在普通小麦中的遗传转化,为利用基因枪介导的遗传转化方法改善小麦籽粒硬度提供了可行性。

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.
