ABSTRACT | Enzyme electrophoresis was used to estimate genetic diversity and population structure of Pyrola japonica KLENZE in Korea. The percent of polymorphic loci within the enzymes was 58.8%. Genetic diversity at both the species level and at the population level was high (Hes = 0.226; Hep = 0.179, respectively) whereas the extent of the population divergence was relatively low (GST = 0.143). FIS, a measure of the deviation from random mating within the 14 populations, was 0.184. An indirect estimate of the number of migrants per generation (Nm = 1.50) indicates that gene flow is moderate among Korean populations of the species. In addition, analysis of fixation indices revealed a substantial heterozygosity deficiency in some populations and at some loci. This indicates that some populations sampled may have been substructured largely due to rhizotamous spread and restricted gene flow coupled with founder effects and genetic drift. |
