番茄种子经搭载返地卫星宇宙飞行３５５ｈ，回收后地面种植，选择３个同工酶有差异的宇宙飞行处理群体植株进行ＲＡＰＤ检测。结果表明：在５０个供试引物中，有１８个扩增出了ＤＮＡ带，共有１６６条，其大小在２００～２０００ｂｐ之间。与地面对照相比，宇宙飞行处理植株的ＤＮＡ在５个引物出现差异，其突变的程度分别为４．５％、１．３％和３．２％。
The tomato seeds were transported back to earth for 355h, and were planted on the ground after the recovery. Three groups of cosmodial groups with different isozymes were selected for RAPD detection. The results showed that among the 50 primers, 18 amplified DNA bands with a total of 166 bands ranging in size from 200 to 2000 bp. Compared with the ground control, the DNA of the plants treated by space flight showed a difference of 5 primers, with the degree of mutation being 4.5%, 1.3% and 3.2% respectively.
