Mitochondrial DNA Diversity of Korean Native Goats
Odahara, S.,Chung, H.J.,Choi, S.H.,Yu, S.L.,Sasazaki, S.,Mannen, H.,Park, C.H.,Lee, J.H. 충남대학교 형질전환복제돼지연구센터 2007 논문집 Vol. No.10
Korean native goats have lived on the Korean peninsula for more than 2,000 years and are regarded as a valuable genetic resource for the world. As an initial step to investigate the genetic structures of this breed, phylogenetic analysis and calculation of genetic diversities have been performed using mitochondrial DNA (mtDNA) sequence variations. A total of 19 Korean native goats were grouped into six haplotypes and the large majority of haplotypes were present in 13 animals. All mtDNA of these Korean goats belonged to the mitochondrial (mt) lineage A and revealed remarkably small genetic distances within the population when compared with other Asian goat populations, indicating less genetic variation in the Korean native goats. These results indicate high-inbred status of the Korean native goats and will influence breeding and conservation strategies adopted for this breed.

Mitochondrial DNA Variation and Genetic Relationships in Japanese and Korean Cattle
Sasazaki, S.,Odahara, S.,Hiura, C.,Mukai, F.,Mannen, H. Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.10
The complete mtDNA D-loop regions of Japanese and Korean cattle were analyzed for their mtDNA variations and genetic relationships. Sequencing the 30 Higo substrain and 30 Tosa substrain of Japanese Brown, respectively 12 and 17 distinct Bos haplotypes were identified from 77 polymorphic nucleotide sites. In order to focus on the relationships among Japanese and Korean cattle, two types of phylogenetic tree were constructed using individual sequences; first, a neighbor-joining tree with all sequences and second, reduced median networks within each Japanese and Korean cattle group. The trees revealed that two major mtDNA haplotype groups, T3 and T4, were represented in Japanese and Korean cattle. The T4 haplogroup predominated in Japanese Black and Japanese Brown cattle (frequency of 43.3-66.7%), while the T3 haplogroup was predominant (83.3%) and T4 was represented only twice in the Korean cattle. The results suggested that the mitochondrial origins of Japanese Brown were Japanese ancient cattle as well as Japanese Black in despite of the considerable introgression of Korean and European cattle into Japanese Brown.
Nuclear structure and β -decay schemes for Te nuclides beyond N=82

<P>We study for the first time the internal structure of Te-140 through the beta-delayed gamma-ray spectroscopy of Sb-140. The very neutron-rich Sb-140 nuclei with Z = 51 and N = 89 were produced by the in-flight fission of U-238 beams at the Radioactive Isotope Beam Factory, RIKEN. The half-life and spin-parity of Sb-140 are reported as 173 +/- 12 ms and 3(-), respectively. In addition to the excited states of Te-140 produced by the beta-decay branch, the beta-delayed one-neutron and two-neutron emission branches were also established. By identifying the first 2(+) and 4(+) excited states of Te-140, we found that Te isotopes persist in their vibrator character with E(4(+))/E(2(+)) = 2. We discuss the distinctive features manifest in this region revealed in pairs of isotopes with the same neutron holes and particles with respect to N = 82.</P>
