以国产基因枪ＪＱ－７００分别将ＧＵＳ（β－葡糖醛酸苷酶）基因射入谷子和玉米的花粉，经人工授粉获得种子。在加卡那霉素（Ｋａｎ）的培养液中筛选获得Ｋａｎ抗性植株。对抗性植株进行ＧＵＳ组织化学和Ｓｏｕｔｈｅｒｎ杂交检测，结果表明有外源基因的整合与表达。转基因谷子和玉米的频率分别为０．１８％和０．０５％～０．２１％。 GUS (β-glucuronidase) gene was injected into pollen of millet and corn with domestic gene gun JQ-700 respectively, and seeds were obtained by artificial pollination. Kan resistant plants were screened in the medium of Kanamycin (Kan). The antagonistic plants were tested by GUS histochemistry and Southern blotting. The results showed that foreign genes were integrated and expressed. The frequency of transgenic millet and maize was 0.18% and 0.05% -0.21%, respectively.
