  • In the previous studies, some genetic polymorphisms in the human mitochondrial DNA have been associated with athletic performance in several populations. To investigate the relationship between mitochondrial DNA 5178A/C polymorphism and athletic performance in Korean population, blood samples were collected from 100 male Korean elite athletes and 64 sedentary controls. There was no significant difference in allele frequency of mitochondrial DNA 5178A/C polymorphism between two groups (P > 0.05). However, 5178A allele frequency in Korean population was very higher than those in other populations studied. Because it has been reported that this genetic polymorphisms is associated with longevity, further study will be needed to clarify the relationship between this genetic polymorphism and life expectancy of Korean population.

  • Eight strains of Trichaptun (Polyporaceae), two strains from each species of T. abietinum, T. biforme, T. fusco-violaceum, and T. laricinum were examined to see their phylogenetic relationship by digesting mitochondrial DNAs with EcoRV, Hind III, XbaI, and PstI, and then analyzing fragmentation patterns with the methods of Nei and Li. T. abietinum, T. biforme, and T. laricinum developed an independent phylogenetic lineage, respectively, but T. fusco-violaceum FP-133997-sp showed a close relationship with two strains of T. bioforme, and T. fusco-violaceum HHB-4016-sp barely grouped with those of T. laricinum. Based on the results of the RFLP analysis of mtDNA, it is concluded that T. fusco-violaceum is under way to differentiation into two different subgroups.
