Genomic Differentiation of Far Eastern Nelumbo nucifera Based on DNA Markers

다국어 초록 (Multilingual Abstract)

Nelumbo nucifera has been used for many purposes from the prehistoric times Today, N nucifera is considered by many botanists as having great potential as a genetic resource This research used molecular markers to identify geographical genomic differentiation of .V nucifera based on the randomly amplified polymorphic DNA(RAPD) method Data matrix was made from 13 primers x 62 genetic characters The profile of amplification products was almost shown to have polymorphic band patterns Numbers of genetic characters represented as autopomorphy and synapomorphy were 3 and 6 each These numbers occupy 14.5% among the total genetic characters These results showed that the genome of N nucifera had high genetic diversity The genome of N nucifera was divided into two subgenomic groups Subgenomic group I was differentiated from an early stage and had great genomic diversity Subgenomic group Ⅱ was differentiated into 3-4 small groups Geographical genomic differentiation of N nucifera is differentiated in three directions from southeastem region(cluster I region) to northwestern region of the Korean peninsula(cluster Ⅱ region)
