激光与DNA非线性作用会使DNA变异、断裂。因此激光辐照DNA导入番茄 ,有利于供体的一些显性基因性状在受体后代得到表达 ,品质得到改善。对细胞色素氧化酶同工酶的研究表明 ,受体后代与受体对照的同工酶图谱差异较大而与供体对照的同工酶图谱差异较小 ,这与它们在叶形与生长型表达上的差异是吻合的。这些表明了激光辐照DNA已经导入受体 ,并得到整合表达 Non-linear laser and DNA will make DNA mutation, fracture. Therefore, the laser irradiation of DNA into tomato is conducive to some of the donor gene expression traits expressed in the recipient, the quality is improved. Studies on cytochrome oxidase isoenzymes showed that isozyme patterns of the progeny and the recipient of the receptor differed greatly but isoenzyme patterns of the isozyme of the donor and the control were smaller, The differences in expression are consistent. These indicate that the laser-irradiated DNA has been introduced into the recipient and has been integratedly expressed
