Objectives : This study was performed to determine if an antler could be identified as one of the Cervus species by phylogenetic analysis, which was used to assess genetic authentication. Methods : The DNAs of an antler were extracted, amplified by PCR, and sequenced. The DNAs of an antler were identified by Phylogenetic analysis. Phylogenetic analysis was made using MEGA software (Molecular Evolutionary Genetics Analysis, 3.1) Results : By phylogenetic analysis an antler was identified as Cervus elaphus nelsoni not as Cervus elaphus sibericus. This work showed that authentication can efficiently be performed by phylogenetic analysis. Conclusion : These results suggest that phylogenetic analysis might be able to provide the authentication of Cervus species.

Fascioliasis is a parasitic infection caused by liver flukes. Although several cases have been reported in Korea, phylogenetic analysis of isolates is lacking. In this study, a 66-year-old woman with right upper quadrant (RUQ) abdominal pain was diagnosed as fascioliasis involving abdominal muscle by imaging study. She received praziquantel treatment, but symptoms were not improved. Lateral movement of the abscess lesion was followed. Trematode parasite was surgically removed from the patient's rectus abdominis muscle. The fluke was identified as Fasciola hepatica based on sequence analysis of 18S rDNA. To determine the phylogenetic position of this Fasciola strain (named Korean Fasciola 1; KF1), the cox1 gene (273 bp) was analyzed and compared with the genes of 17 F. hepatica strains isolated from cows, sheep, goats, and humans from various countries. Phylogenetic analysis showed that KF1 was closely related with the isolates from China goat.

The phylogenetic study of Penicilium chrysogenum was performed based on amino acid sequence comparison of chitin synthase. Phylogenetic trees were constructed with the deduced amino acid sequences of the highly conserved region of chitin synthease gene fragments amplified by PCR. The BlasP similarity searcch and the bootstrap analysis of the deduced amino acid sequences of chitin synthase from P. chrysogenum with those form other fungi showed a close evolutionary relationship of Penicillium to ascomycetous fungi, especially to genus Aspergilus. The result from bootstrap analysis of the deduced amino acid sequences of the Class II chitin synthase from ascomyceteous fungi supported the usefulness of the Class II chitin synthease for phylogenetic study of filamentous fungi.

동양달팽이의 EST 서열 4개의 클론을 어셈블리하여 추출되어진 NsCO-I (partial)서열의 코딩 영역은 852 bp, 284개의 아미노산으로 구성되어 있었다. BLAST 결과를 토대로 하여 유사도가 높은 68개의 서열을 추출 하였으며 MEGA6 프로그램을 통해 clustalW 엔진을 통해 다중서열정열을 수행하고 molecular phylogenetic analysis를 수행한 결과 Heterobranchia, Nudibranchia, Cephalaspidea, Sacoglossa, Pulmonata 등의 카테고리별로 잘 분류 되었으며 Mastigeulota kiangsinensis, Helix aspersa, Cepaea nemoralis, Elona quimperiana, Camaena cicatricosa, Cylindrus obtusus 등 육산패류들과 잘 묶인다는 사실을 확인 할 수 있었다.

Lilium is a perennial bulbous plant belonging to the liriotypes genus. Our aim was to study the phylogenetic relationships of the Lilium family. Two varieties of Lilium ledebourii, 44 varieties of the gene bank, and one variety from the Tulipa family served as the out group. In order to study the diversity between lilium masses, ITS regions were used to design the marker. The results showed that the guanine base is the most abundant nucleotide. Relatively high conservation was observed in the ITS regions of the populations (0.653). Phylogenetic analysis showed that sargentiae and hybrid varieties are older than other varieties of the Lilium family. Also, the location of L. ledebourii varieties (Damash and Namin) was identified in a phylogenetic tree by using the ITS marker. Overall, our research showed that ITS molecular markers are very suitable for phylogenetic studies in the Lilium family.

Molecular phylogenetic analyses of Korean Elaeagnus L. were conducted using seven species, one variety, one forma and four outgroups to evaluate their relationships and phylogeny. The sequences of internal transcribed spacer regions in nuclear ribosomal DNA were employed to construct phylogenetic relationships using maximum parsimony (MP) and Bayesian analysis. Molecular phylogenetic analysis revealed that Korean Elaeagnus was a polyphyly. E. umbellata var. coreana formed a subclade with E. umbellata. Additionally, the genetic difference between E. submacrophylla and E. macrophylla was very low. Moreover, E. submacrophylla formed a branch from E. macrophylla, indicating that E. submacrophylla can be regarded as a variety. However, several populations of this species were not clustered as a single clade; therefore, further study should be conducted using other molecular markers. Although E. glabra f. oxyphylla was distinct in morphological characters of leaf shape with E. glabra. But E. glabra f. oxyphylla was formed one clade by molecular phylogenetic with E. glabra. Additionally, this study clearly demonstrated that E. pungens occurs in Korea, although it was previously reported near South Korea in Japan and China. According to the results of ITS regions analyses, it showed a resolution and to verify the relationship between interspecies of Korean Elaeagnus.

Phylogenetic analyses on the Phylum Mollusks has so far been conducted by many researchers in the world. However, there was no report on taxonomic analysis on Acila divaricata vigila which is belonging to Class Bivalvia, Subclass Protobranchia. In this study, we performed molecular phylogenetic analysis on Acila divaricata vigila using 16S rRNA sequence through maximum likelihood method. As a result, it is clearly divided into the legion of mollusk classification unit (when you zoom in order) and represented to support the current classification in the Phylum Mollusca belong to Class Bivalvia, Subclass Protobranchia, Subclass Pteriomorphia, Subclass Paleoheterodonta, Subclass Heterodonta and Subclass Anomalodesmacea. To our knowledge, this is the first report of molecular phylogenetic analysis on Acila divaricata vigila using 16S rRNA gene and these data suggests that 16S rRNA gene will be useful for analyzing the phylogenetic relationship of Subclass Protobranchia.

엽록체 DNA atpF-H, psbA-trnH region을 마커로 활용하여 국내에 분포하는 소나무속 식물들 중 17분류군에 대한 분자계통학적 연구를 수행하여 한국산 소나무속의 계통학적 유연관계를 규명하고, 소나무속의 유연관계를 잘 나타낼 수 있는 분자마커를 찾아내고자 연구가 수행되었다. atpF-H, psbA-trnH region의 조합분석결과 한국산 소나무속은 100%의 BP로 지지되는 단계통군으로 확인되었으며, 소나무아속과 잣나무아속으로 명확히 구분되어졌다. 본 연구에서 이용된 두 개의 분자마커 중 psbA-trnH region이 atpF-H region보다 한국산 소나무속의 계통 및 유연관계를 규명하는데 다소 높은 해상력을 나타내었다.

Taxonomic and phylogenetic studies of firefly in Japan have been reviewed. Fourty-six lampyrid species and one rhagophthalmid are distributed in the Japanese Islands including the Ryukyus. Recently, molecular phylogenetic approaches have been employed in the systematic study of firefly using mitochondrial and luciferase genes. Based on the molecular phylogenetic trees, evolutionary process of flashing patterns related strictly to mating behavior was estimated. Furthermore, genetic diversity studies revealed geographic differentiation patterns within species, and conservation measures of firefly were proposed to protect genetic resources endemic to the localities.
