  • 행정자치부 소방국이 매년 화재건수를 조사, 분석한 통계에 따르면 97년 한해동안 발생된 화재중 전기화재는 약 34.2%의점유율을 차지해 여전히 1위를 고수하고 있다. 이는 미국, 일본보다 높은 수치이며 노후 전기설비등 개선대책 마련이 시급하고 미확인 화재는 전기화재를 집계하는 문제 등을 내포하고 있다.

  • Endophytic fungal strains were isolated from the sterilized roots of a medicinal plant, Ligusticum chuanxiong and identified based on morphological characteristics and molecular analysis of internal transcribed spacer, large subunit rDNA, and beta-tubulin DNA regions. Our results confirmed the presence of Pithomyces chartarum and Plectosphaerella niemeijerarum in the fungal strains. To the best of our knowledge, the fungal strains have not been reported in Korea. In this report, we describe morphological characteristics and phylogenetic trees of these endophytic fungal strains.

  • We isolated endophytic fungi from the coniferous leaves of Abies koreana and Taxus cuspidata inhabiting Mt. Hallasan, Korea. The isolated fungal strains were identified based on a phylogenetic analysis using nucleotide sequences of the internal transcribed spacer region, large subunit region of ribosomal DNA, and translation elongation factor region. Results confirmed four prevously unreported endophytic fungi in Korea: Lachnellula hyalina, Ochrocladosporium elatum, Phacidium lacerum, and Phyllosticta cussoniae. In this report, we describe the morphological characteristics of these fungi and the results of the phylogenetic analysis.

  • We isolated endophytic fungal strains from the leaves of Abies koreana growing in Korea. The fungal strains were identified as Coleophoma parafusiformis and Coniochaeta ligniaria, based on morphological characteristics and sequence analysis of the internal transcribed spacer region and large subunit region of ribosomal DNA. These species have not been previously reported in Korea. In this study, we report the morphological characteristics and results of phylogenetic analysis of the two novel fungal strains.

  • Endophytic fungi were isolated from the leaves of plants inhabiting the Hansando Island in Korea. We identified the fungal strains based on their morphological characteristics and on the phylogenetic analysis using DNA sequences of the internal transcribed spacer, small subunit rDNA, large subunit rDNA, and translation elongation factor 1- α regions. In this study, we isolated five endophytic fungi that have not been recorded in Korea, Arthrinium camelliaesinensis, Beltraniella humicola, B. portoricensis, Microxiphium theae, and Piceomphale pinicola. Their morphological characteristics as well as the results of molecular phylogenetic analysis are reported here.

  • We isolated fungal spores belonging to the phylum Glomeromycota from the rhizospheres of Smilax china, cultured in a greenhouse. We identified the isolated spores using sequence analysis of 18S partial rDNA region, internal transcribed spacer and 28S rDNA regions. We confirmed 2 unreported spores of Glomeromycota fungal species, Diversispora eburnea and Paraglomus laccatum. Here, we described the morphological characteristics and results of phylogenetic analysis of the confirmed species.

  • Endophytic fungi were isolated from the leaves of diverse plants inhabiting Jeju Island, Korea. The fungal isolates were identified through phylogenetic analyses incorporating nucleotide sequences derived from the internal transcribed spacer region, large subunit region of ribosomal DNA, and beta-tubulin gene. Our results identified six endophytic fungi previously unknown in Korea namely, Diaporthe goulteri, Diaporthe vaccini, Rhizosphaera pini, Valsa friesii, Xylaria primorskensis, and Zalerion arboricola were identified. Here, we present their cultural and morphological characteristics and phylogenetic relationship.

  • We isolated endophytic fungal strains from the roots of three medicinal crops, Ligusticum chuanxiong, Angelica gigas, and Cnidium officinale, cultivated at Yeongju, Korea. The fungal strains were identified based on their morphological characteristics and molecular analyses of their internal transcribed spacer, large subunit rDNA, and beta-tubulin regions. Thereby, we identified three previously unrecorded endophytic fungal species, Dactylonectria pauciseptata, Rhizopycnis vagum, and Sistotrema sernanderi, in Korea. In this report, we describe the morphological characteristics and phylogenetic analyses of these three fungal species.
