将甘蔗近缘植物陇川割手密 DNA提取液分别以共培养导入法和基因枪导入法转导到桂糖 11号的离体细胞内并分化成苗。结果 ,基因枪导入法获得的变异株系与供体桂糖 11号相比 ,其叶片过氧化物酶同工酶谱有差异 ,而共培养导入法获得的转导再生变异苗的叶片过氧化物酶同工酶谱与供体桂糖 11号的完全一致 The sugarcane-related plants Longchuan cut hand Mipi DNA extract were introduced by co-culture and gene gun into Guitang No. 11 in vitro cells and differentiated into seedlings. As a result, the variation of the peroxidase isoenzyme pattern of the mutant strains obtained by the gene gun introduction method was different from that of the donor Guitang 11, while the leaf peroxidation of the transduced regenerated mutant seed obtained by the co-culture introduction method The isozyme pattern of the enzyme is exactly the same as that of donor Guitang 11
