【摘要】 本文利用花粉管通道在大豆自花受粉后,将野生大豆DNA导入栽培大豆,从而引起了后代性状的广泛变异。结果进一步证明了外源DNA片段直接导入受体植物卵细胞、合子或早期胚细胞,部分片段可被受体细胞DNA整合乃至表达理论的可行性和实用价值。更多还原

【Abstract】 This study reports that wild soybean DNA was introduced into cultivar soybean through pollen tube after soybean self-fertilizing,it led to wide variation in offspring characteristics.This indicates that outside DAN segments can be directly introduced into host plant egg cells,zygotes or early embryos,some segments can insert into host cell DNA and express.The study shows this method has significant practical value for breeding.更多还原
