Mycobacteria에 대해 항균력을 나타내는 엉겅퀴의 분류를 위한 ITS1, 5,8S rRNA, ITS2의 염기서열 분석

국문 초록 (Abstract)

세균 및 진균류의 증식을 억제하는 능력이 있는 것으로 보고된 누로와 대계의 추출물을 사용하여 Mycobacterium smegmatis 및 Mycobacterium fortuitum의 증식을 억제하는 능력이 있는지를 시험하였다. 그 결과, 누로의 추출물에서는 증식억제능을 발견할 수 없었으나, 대계의 추출물에서는 뚜렷한 증식억제능이 관찰되었다. 따라서 본 연구에 사용된 대계(엉겅퀴)에 대한 분류학적 또는 진화적 분석을 수행하기 위하여 genomic DNA를 추출한 후, ITSl, 5.85 rRNA 유전자 및 ITS2를 포함하는 부분을 PCR로 증폭시켰다. PCR 산물의 염기서열을 분석한 결과, 733-bp의 염기서열이 얻어졌고, 이것을 GenBank에 등록하였다(accession number GU188570). 이렇게 얻어진 염기서열을 사용하여 BLAST analysis를 수행한 결과, 염기서열이 일치하는 생물체는 아직까지 GenBank에 보고된 적이 없고, 가장 가까운 식물들로는 귀화식물로서 전국적으로 분포하는 Carduus crispus (지느러미엉겅퀴) 및 현재까지 국내에 자생하는 것으로 보고된 적이 없는 Carduus defloratus로서 각각 3개씩의 염기가 다른 것으로 나타났다.

다국어 초록 (Multilingual Abstract)

It has been reported that extracts of globe thistle (Echinops spp.) and thistle (Circium spp., Carduus spp. and Onopordum spp.) have anti-bacterial and anti-fungal activities. Methanol extracts of Echinops setifer and Carduus spp. were used to test and see if the extracts of these plants could suppress growth of Mycobacterium smegmatis and Mycobacterium fortuitum. Although extract of Echinops setifer showed no anti-mycobacterial activities, extract of Carduus spp. showed inhibition zones when tested with filter discs. Genomic DNA was isolated from Carduus spp. and PCR was performed to clone a DNA fragment containing ITS1, 5.8S rRNA gene and ITS2. A 733-bp PCR product was obtained and its DNA sequence was reported to the GenBank (accession number GU188570). BLAST search of the obtained DNA sequence did not show a match with any DNA sequences in the Genbank. Carduus crispus and Carduus defloratus had the closest phylogenetic relationships to this plant.
