In this study,the ovary-drip method with higher transformation frequency and reproducibility was established for soybean. In addition,a marker-free and vector-free AlNHX1 gene cassette was transferred into soybean via ovary-drip method.
本研究优化了一种转化率较高、重复性较好的大豆子房滴注法,通过该方法将无载体骨架序列无选择标记的AINHX1基因元件导入大豆,提高了大豆的耐盐性,为其它功能基因在大豆转化中的应用奠定了基础。
