摘    要:选用对TMV有抗性和敏感的番茄品种、制备其ct-DNA, 用限制性内切酶BumHI、EcoRI和PstI完全酶解, 三种酶切图谱与前人报道一致, 由酶切片段计算番茄ct-DNA。分子量约为156.9kb。比较抗性和敏感品种的ct-DNA图谱, 发现三种酶切图谱均存在差异, 但由差异片段计算分子量之和又很除近。我们推测这是由于检基顺序变异或小段DNA顺序插入或缺失所造成, 由此证明, 叶绿体基因组与核中的TMV抗性基因, 共同决定着植物体对TMV的抗性。

关 键 词:番茄  TMVct-DNA  限制性内切酶

Abstract:We analyze ct-DNA of tomato which is resistant and sensitive to TMV with restriction enzyme. Our electrophoretogram of BamHI, EcoRI. Pst I is similar to other report.Molecular weight of ct-DNA is 156. 9kb, it is similar to others' study.We find some difference in BamHI EcoRI, PSt I electrophoretogram between resistant group and sensitive group. We guess this maybe the alternation of base sequence or insertion or deletion of short DNA sequence. We also infer that nucleus genome and chloroplast genome together decide the resistance of plant to Tobbacco Mossic Virus.
Keywords:Tomato  TMV  ct-DNA  Restriction endonucleases.
