구지뽕 나무의 엽록체 TrnL-F 영역 염기서열 분석을 통한 특이적 SNP 분자마커의 확인

초록

Cudrania tricuspidata Bureau is a widely used medicinal perennial woody plant. For conservation and germplasm utilization of the plant, it is imperative to obtaining information regarding the genetic diversity of the plant populations. Although C. tricuspidata is an important medicinal plant registered in South Korea, no molecular markers are currently available to distinguish Korean-specific ecotypes from other ecotypes of different countries. In this study, we developed single nucleotide polymorphism (SNP) markers derived from chloroplast genomic sequences to identify distinct Korean-specific ecotypes of C. tricuspidata via the amplification refractory mutation system (ARMS)-PCR analyses. Molecular authentication of twelve C. tricuspidata ecotypes from different regions was performed, using DNA sequences in the trnL-F chloroplast intergenic region. The SNP markers developed in this study are useful for rapidly identifying specific C. tricuspidata ecotypes from different regions. ? Korean Society for Plant Biotechnology.
