RAPD 분석에 의한 고마리(마디풀과)의 유전적 변이 및 유연관계
Genetic Variations and Relationships of Persicaria thunbergii (Sieb. &Zucc.) H. Gross ex Nakai (Polygonaceae) by the RAPD Analysis
RAPD analyses were performed from twenty-four populations of Persicaria thunbergii (Sieb. & Zucc.) H. Gross ex Nakai. The length of amplified DNA fragments ranged from 200 to 1,900bp. 184 scorable RAPD markers were found from PCR reactions with sixteen random oligoprimers. Based on the results, populations of Persicaria thunbergii were classified into disturbance streams of urban and rural streams as well as natural streams. And the populations from natural streams showed having higher genetic similarites than those from highly disturbed streams. Also, the heterogenetic differences between the populations from natural and disturbed areas could be represented the results of the stream environmental changes.
