  • Euphorbia ebracteolata Hayata is a perennial herb of Euphorbiaceae that has a cyathumal inflorescence, the glands of the involucres are rounded-cordate and reddish, stems are erect, thick and 40-50 cm high. The leaves are alternate and rather numerous. So far this plant has been known as a unreported species in Korea. However, as the result of this study, this plant was found to be widely distributed in Korea over eight habitats, i.e. Keunduk, Dokye and Kaliwangsan, Kangwon-do: Dunduksan, Kyongsangbuk-do: Okcheon, Chungcheongbuk-do: Manduksan, Baekyangsan and Naejangsan, Jeolanam-do. On the other hand, its variety, E. ebracteolata var. coreana Hurusawa which grows only in Poong-do, Kyongki-do was reviewed by comparative morphology and chemotaxonomy to be resulted in the same species, E. ebracteolata.

  • 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.

  • We isolated endophytic fungi from the leaves of the conifer Juniperus chinensis var. sargentii inhabiting Mt. Hallasan. The fungal isolates were identified based on phylogenetic analysis using nucleotide sequences of the internal transcribed spacer region, large subunit region of ribosomal DNA, translation elongation factor, and ${\beta}$-tubulin region. In this study, we confirmed four species of unreported endophytic fungi in Korea, Allantophomopsis lycopodina, Epicoleosporium ramularioides, Kabatina juniperi, and Seiridium podocarpi. We describe their morphological characteristics and the results of the phylogenetic analysis.

  • The purpose of this study was to isolate and identify wild yeasts from the soil collected in Gwangju and Pocheon City, Gyeonggi Province, Republic of Korea. Among 10 strains, six strains were already reported, but four strains were unrecorded in Republic of Korea. To identify wild yeast strains, pairwise sequence comparisons of the D1/D2 region of the 26S rRNA gene sequence were performed using Basic Local Alignment Search Tool (BLAST). The cell morphologies were observed by phase contrast microscope and assimilation tests were carried out using API 20C AUX kit. The 10 strains were assigned to the phyla Basidiomycota (8 strains) and Ascomycota (2strains). The unrecorded four yeast strains, NH33, NH19, NH20, and YP416, belong to the phylum Basidiomycota and the genera Buckleyzyma, Leucosporidium, Holtermanniales, and Mrakia, respectively. All strains had oval-shaped and polar budding cells. In this research, the morphological and biochemical properties of four unreported yeast species were characterized intensively, which were not officially reported in Korea.

  • In this study, the fungal strain KNUF-21-F39 was isolated from a declined apple tree (Malus domestica) in the Chungcheongbuk province in Korea. The strain KNUF-21-F39 presented a slow growth rate and a variety of macroconidia shapes and sizes ranging from ovoid to fusoid and 1- to 5-septate, primarily showing 3- and 4-septate, with "S" -shaped macroconidia rarely observed. The strain was identified based on morphological characteristics along with phylogenetic analysis performed using the internal transcribed spacer region (ITS) and partial sequences of translation elongation factor 1-α (tef1), RNA polymerase largest subunit (rpb1), and calmodulin (cal) genes. The fungal strain KNUF-21-F39 was identified as Fusarium diversisporum, which has not been previously reported in Korea. The ice nucleation activity (INA) of the strain was also evaluated, identifying the strain as positive for INA. This is the first report characterizing F. diversisporum as an IN-active fungal species.

  • In this study, we aimed to study carnation italian ringspot virus (CIRV) in Erigeron annuus (L.) Pers. in Bonghwa County, Korea. The collected samples showed mosaic and malformation symptoms. To identify the virus species, we performed high-throughput sequencing, reverse transcription polymerase chain reaction, and cloning. The virus was confirmed to be an unreported species, and therefore we performed genome sequencing of the samples. The complete genome was 4,746 nucleotides in length. The CIRV contained five open reading frames (ORFs), and it showed the typical features of members of the genus Tombusvirus. Phylogenetic analyses revealed that ClRV isolates had the highest nucleotide identities with the CZ isolate (95.89%) from Korea. In recent years, these viruses have sporadically been reported in floral scent and medicinal plants. This research found the first natural host infected with CIRV, and provides baseline information to determine the correlation between weeds and crops.

  • An unstable yet efficient phenanthrene-degrading bacterium strain Ph-3 was isolated from a petroleum-contaminated site at the Mathura Oil Refinery, India. The strain was identified as Pseudomonas sp. using a polyphasic approach. An analysis of the intermediates and assays of the degradative enzymes from a crude extract of phenanthrene-grown cells showed a novel and previously unreported pattern of 1, 2-dihydroxy naphthalene and salicylic acid production. While strain Ph-3 lost its phenanthrene- degrading potential during successive transfers on a rich medium, it maintained this trait in oligotrophic soil conditions under the stress of the pollutant and degraded phenanthrene efficiently in soil microcosms. Although the maintenance and in vitro study of unstable phenotypes are difficult and such strains are often missed during isolation, purification, and screening, these bacteria constitute a substantial fraction of the microbial community at contaminated sites and play an important role in pollutant degradation during biostimulation or monitored natural attenuation.
