PCR-aided RFLP기술을 이용한 인삼의 DNA분석

다국어 초록 (Multilingual Abstract)

This study was carried out to obtain basic information on breeding using PCR-aided RFLP technology which can identify the variation inter- and intra-species of ginseng in the level of DNA. It was intended to investigate banding pattern on psbA and rbcL genes of chloroplast DNA in ginseng after treating with restriction enzymes. To isolate psbA and rbcL genes of chloroplast, both psbA-N, psbA-C primer and rbcL-N, PX-1 primer were used. As a result, 1,008 bp<br/>
band of psbA gene and 1, 336bp band of rbcL gene were appeared, which was optimal and expected molecular weight. In addition, primers to isolate atpB, rpoB, trnL, and trnF genes were used, resulting in the expected 1366, 900, 1500 and 1008 bp bands. Genes of psbA and rbcL isolated by PCR were cut by restriction enzymes, Sau3A, TaqI, AluI, HaeIII, and RFLP pattern was investigated. KG line and other species of ginseng were cut by TaqI treatment, and bands were located in 800 bp. The treatment treated by AluI also showed the same 800 bp band in KG line and other species. In HaeIII treatment, 500 bp of faint bands were shown in case of KG line, whereas any bands were not observed in other species. All<br/>
chloroplast genes formed bands by PCR amplification. However, it was not evident to distinguish intra-or inter-species of ginseng after restriction enzyme treatment. Therefore, more restriction enzyme treatment or sequence comparison method should be considered for further experiment.
