本文分析了利用花粉管通道导入外源DNA所获得的变异后代(D_2)的过氧化物酶同工酶酶谱。结果表明,酶谱谱带清晰,变异后代的各株系的酶谱与其亲本的酶谱差异明显。所有的材料除具有两条共同的谱带外,在表型变异明显的各株系间,其酶谱差异很大。这表明外源DNA片断已整合到受体基因组中,或调控了受体某些基因并得到表达。 In this paper, we analyzed the peroxidase isoenzyme patterns of mutant progenies (D 2) obtained by introducing foreign DNA with pollen tube channels. The results showed that the zymogram bands were clear, and the zymogram of each strain of the mutant progeny was significantly different from that of its parental zymogram. In addition to having two common bands for all materials, there are significant differences in their zymograms between strains with significant phenotypic variability. This indicates that the exogenous DNA fragments have been integrated into the recipient’s genome or have regulated some of the receptors and expressed.
