摘要: 根据烟草和大麦中反转录转座子Bare-1和Tto1的LTR保守区域设计引物,对14份茄子材料进行PCR扩增,分别采用琼脂糖和聚丙烯酰胺凝胶电泳检测扩增产物,建立了茄子IRAP(inter-retrotransposon amplified polymorphism)和REMAP(retrotransposon-microsatellite amplified polymorphism)分子标记技术体系。两种方法均得到了多态性丰富的指纹图谱,为茄子品种鉴定和指纹图谱构建提供了新途径。

关键词: 茄子, 反转录转座子, IRAP, REMAP

Abstract: Primers were designed based on LTR reserve region of Bare-1 and Tto1 in tobacco and barley.14 varieties of eggplant were used as experimental materials for PCR amplification.Agarose and polyacrylamide gel electrophoresis were adopted to detect amplification products and the technique of IRAP and REMAP molecular marker was constructed.Polymorphic fingerprints were obtained using two methods (IRAP and REMAP),new methods were developed for variety appraisal and fingerprint in eggplant.

Key words: eggplant, retrotransposon, IRAP, REMAP
