Abstract
Inter-simple sequence repeat (I-SSR) markers were analyzed from diploid genomes of 95 nutmeg trees (Torreya nucifera Siev. et Zucc.) in 5 populations. A total of 62 I-SSR amplicons were observed and 7 of them were monomorphic in 95 individuals. DNA fingerprint of each tree was verified by pooling the observed I-SSR amplicons. Most of the genetic diversity was allocated within population (90.65%) and all the populations revealed similar level of I-SSR amplicon diversity within population. Degree of population differentiation (
국내 5개 지역에서 채집한 비자나무(Torreya nucifera Siev. et Zucc.) 95개체를 대상으로 I-SSR 표지자를 분석하였다. 총 62개의 I-SSR 증폭산물(增幅産物)이 관찰되었으며, 그 중 7개의 증폭산물(增幅産物)은 분석된 95개 개체에서 단형성(單形性)이었다. 관찰된 전체 I-SSR 증폭산물(增幅産物)을 통합(統合)하여 분석한 결과 개체목에 대한 DNA지방판별(指放判別)이 가능하였다. 대부분의 유전다양성(遺傳多樣性)이 임분(林分)내의 개체목 간에 존재하는 것으로 나타났고(90.65%), 전체 5개 임분(林分)에서 유사한 수준의 유전다양성(遺傳多樣性)을 보였다. 집단간의 유전적(遺傳的) 분화(分化)정도는 심하지 않았다(
