Candida glabrata is the second most prevalent causative agent for candidiasis following C. albicans. The opportunistic yeast, C. glabrata, is able to cause the critical bloodstream infections in hospitalized patients. Conventional identification methods for yeasts are often time consuming and labor intensive. Therefore, recent studies on sequence-based identification have been conducted. Recently, sequencing the D1/D2 domain of the large subunit ribosomal RNA gene and the internal transcribed spacers (ITS) 1 and ITS2 regions of the ribosomal DNA has proven useful for DNA-based identification of most species of fungi. In the present study, therefore, fungal ITS and D1/D2 domain regions were targeted and analyzed by DNA sequencing for the accurate identification of C. glabrata clinical isolates. A total of 102 C. glabrata clinical isolates from various clinical samples including bloodstream, catheterized urine, bile and other body fluids were used in the study. The results of the DNA sequence analysis showed that the mean standard deviation of species identity percent score between ITS and D1/D2 domain regions was $97.8%{\pm}2.9$ and $99.7%{\pm}0.46$, respectively. These results revealed that the D1/D2 domain region might be a better target for identifying C. glabrata clinical isolates based on DNA sequences than the ITS1 and ITS2 regions. However, in order to evaluate the usefulness of D1/D2 domain region for species identification of all Candida species, other Candida species such as C. albicans, C. tropicalis, C. dubliniensis, and C. krusei should be verified in further studies additionally.

Agaricus 속의 계통분류학적 유연관계를 알아보기 위하여 Internal transcribed spacers 1,2, 와 5.8S rDNA 에 해당하는 부위를 PCR 기법으로 증폭하여 염기서열을 비교 조사하였다. 본 실험에 사용되어진 aGARICUS 속 5균주에 대한 염기서열을 분석한 결과, 이들 속은 크게 두 개의 군으로 분류되었다. 첫 번째 분류군은 aGARICUS BLAZEI atcc 76739, 현재 우리나라에서 배양중인 Agaricus blazei, agaricus arvensis IMSNU 32049, 그리고 Agaricus campestris VPI-OKM 25665로 이루어 졌다. 특히, Agaricus blazei ATCC 76739와 현재 우리나라 농가에서 배양중인 Agaricus blazeisms ITS 부위에서 5개의 염기서열에서 변이가 발견되었다. 이러한 변이는 지리적 또는 배양상의 변이로 인하여 특정염기서열에서 변이가 발생한 것으로 간주되므로 이들은 상호 동일종일 것으로 추정된다. 또한, Agaricus arvensis IMSNU 32049 와 Agaricus ampestris VPI-LKM 25665는 Agaricus blazei 하위 분류군을 형성하였다. 두 번째 분류군은 Agaricus bisporus CH 3004와 Agaricus pocillator DUKE-J 173 으로 이루어졌다.

The bramble cultivated widely in South Korea, which is known as Bokbunja-ddal-gi, is regarded as having originated from Korean native Rubus coreanus. This study was carried out to obtain basic phylogenetic information on Korean cultivated bramble (KCB) by comparing the internal transcribed spacer (ITS) regions with those of R. coreanus, blackberry (R. lanciniatus), black (R. occidentalis) and red (R. idaeus) raspberry. Sequences of the ITS 1 suggest that some KCB accessions share a significant similarity with both R. occidentalis and R. coreanus in the ITS 1 region. The ITS 2 sequences of the three KCB accessions clustered more closely to those of two R. occidentalis accessions than to those of R. coreanus. These results suggest that there exist variations in the sequences of ITS among KCB accessions and KCB accessions are more closely related to black raspberry than R. coreanus in the ITS regions.

Background : Plants belonging to 5 species of the genus Eleutherococcus are currently distributed in the Korean peninsula. The traditional medicine 'Ogapi', derived from Eleutherococcus sessiliflorus and other related species, and 'Gasiogapi', derived from Eleutherococcus senticosus, are frequently mixed up and marketed. Therefore, accurated identification of their origins in urgently required. Methods and Results : Candidate genes from nuclear ribosomal DNA (nrDNA) and chloroplast DNA (cpDNA) of Eleutherococcus plants were analyzed. Whereas the nrDNA-internal transcribed spacer (ITS) regions were useful in elucidating the phylogenetic relationships among the plants, the cpDNA regions were not as effective. Therefore, a combined analysis with nrDNA-ITS was performed. Various combinations of nrDNA and matK were effective for discriminating among the plants. However, the matK and rpoC1 combination was ineffective for discriminating among some species. Based on these results, it was found that OG1, OG4, OG5, OG7, GS1, GS2, and GS3 were derived from E. sessiliflorus. In particular, it was confirmed that GS1, GS2, and GS3 were not derived from E. senticosus. However, more samples need to be analyzed because identification of the origins of OG2, OG3, OG6 and GS4 was not possible. Conclusion : The ITS2, ITS5a, and matK combination was the most effective in identifying the phylogenetic relationship among Eleutherococcus plants and traditional medicines based on Eleutherococcus.

The relativity of four isolates of C. polykrikoides was determined by comparative sequence analysis based on direct sequencing of PCR amplified ribosomal DNA (the internal transcribed spacer region and the 5.8S rDNA). Sequence comparisons indicated that four isolates had the same nucleotide sites in the ITS regions, as well as a total of 585 nucleotide length and 100% homology. The molecular data revealed that C. polykrikoides in Korean coastal waters show no genetical difference.
