  • As a subset study to discover indigenous prokaryotic species in Korea in 2014, a total of 34 bacterial strains assigned to the phylum Actinobacteria were isolated from various environmental samples collected from activate sludge, biotite, freshwater, gut of marine organisms, mud flat, sediment, soil, spent mushroom compost and sea water. On the basis of high 16S rRNA gene sequence similarity and a tight phylogenetic association with the closest species, it was revealed that each strain was assigned to independent and previously described bacterial species, with the exception of one isolate. There is no official report that these 34 species included in the phylum Actinobacteria have been described in Korea: 6 species of 5 genera in the order Corynebacteriales, 1 species of 1 genus in the order Frankiales, 2 species of 2 genera in the Micromonosporales, 14 species of 10 genera in Micrococcales, 2 species of 2 genera in the Propionibacteriales, 1 species of 1 genus in the Pseudonocardiales, 4 species of 2 genera in the Streptomycetales, 2 species of 2 genera in the Streptosporangiales and 1 species of 1 genus in the Solirubrobacterales. Gram reaction, cell and colony morphology, pigmentation, physiological characteristics, isolation sources and strain IDs are described in the section of species description.

  • During recent screening to discover indigenous prokaryotic species in South Korea, a total of 31 bacterial strains assigned to the class Gammaproteobacteria were isolated from a variety of environmental samples including soil, tidal flat, freshwater, seawater, and plant roots. From the high 16S rRNA gene sequence similarity (>98.7%) and formation of a robust phylogenetic clade with the closest species, it was determined that each strain belonged to each independent and predefined bacterial species. There is no official report that these 31 species have been described in South Korea; therefore 5 species of 3 genera in the order Alteromonadales, 11 species of 3 genera in the order Pseudomonadales, 8 species of 6 genera in the order Enterobacteriales, 2 species of 1 genera in the order Vibrionales, 1 species of 1 genera in the order Oceanospirillales, 3 species of 3 genera in the order Xanthomonadales, and 1 species in the order Spongiibacter_o within the Gammaproteobacteia are reported for proteobacterial species found in South Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are also described in the species description section.

  • The filamentous freshwater red alga Compsopogon caeruleus(Compsopogonophyceae, Compsopogonaceae, Rhodophyta) occurs in tropical and subtropical regions of worldwide. This species has been reported from Asia, America, Africa, Europe and Oceania, and the worldwide distribution of Compsopogon caeruleus is in variable water habitats. Several morphospecies of the genus Compsopogon had been recorded, but recent molecular phylogenetic analyses with worldwide sampling identified a monospecific genus, C. caeruleus. In the present study, we first report a freshwater red alga Compsopogon caeruleus from Korea. We identified Compsopogon caeruleus in an urban river in Yongin City, and analyzed its morphological and genetic characteristics. Nuclear 18S rDNA, plastidal rbcL gene and mitochondrial cox1 gene sequences isolated from Korean Compsopogon caeruleus showed high sequences similarity with Compsopogon caeruleus from worldwide (98.6-100% (18S rDNA), 99-100% (rbcL) and 97.7-100% (cox1)). These sequences similarities support the identification of a red alga found in Korea as Compsopogon caeruleus. This new geographical report provides the useful information for understanding the distribution and habitat range of Compsopogon caeruleus especially concerning urban freshwater environments.

  • Objectives : Through surveying the vegetation of woody plants naturally growing in the Chonnam Area. we expect to make good use of the surveyed data for the conservation and utilization of woody plants in the Chonnam Area. And also we hope that we could make a good opportunity to love and conserve the Chonnam Area through this report. Methods : we inspected native and cultivated medicinal woody plants in the Chonnam Area by report and survey, and researched medicinal part through the herbalogy literature. Results : 1. According to the investigation of medicinal woody plant in the Chonnam area, it bears 189 species, 139 genera and 62 families. 2. Rosaceae and Quercus are the biggest share of medicinal woody plants in the Chonnam area. 3. In aspect of medicinal part, roots of 100 species, leaves of 102 species, fruits of 80 species, and barks of 67 species have been using. The leaves part of the most plants are abundantly used. 4. About 30 species of medicinal woody plants are distributed distinctively in Korea. Conclusions : According to the investigation of medicinal woody plant in the Chonnam area, it bears 189 species, 139 genera and 62 families.

  • An aeolid nudibranch species Flabellina athadona (Bergh, 1875) is newly recorded from Korean waters. This species is distinguished from other congeneric species by the following characteristics: translucent white body, deep orange colored digestive glands, plenty of white specks, and a reversed Y-shaped marking on the head between rhinophores and oral tentacles. In this report, we also provide an identification key for the genus Flabellina in Korea, photographs, and diagnostic characteristics of F. athadona. Molecular identification using mtDNA cox1 partial sequences is also provided to help differentiate F. athadona from some of its closely related congeneric species.

  • One newly recorded species, Dryopteris namegatae, sect. Hirtipedes, was collected in forests in Jeju-do. Dryopteris namegatae (vernacular name: 'Tam-ra-top-ji-ne-go-sa-ri') was distinguished from other Korean congeners of sect. Hirtipedes of the genus Dryopteris by having stiff black scales on stipe and rachis, less narrowed base of lamina, and adaxial surface of pinna immersed along veins. Dryopteris hangchowensis ('Gak-si-top-ji-ne-go-sa-ri', new local name), recorded without any comments and description, was reexamined with similar taxa and was distinguished by smaller plants, brilliant leaves, many prominent fimbriate blackish scales on stipe and rachis, long-pointed apex of lamina and pinna, halfway-lobed pinna, and narrowest pinna. Descriptions and illustrations of the two species and their photographs in the habitat are provided along with a key to the species of sect. Hirtipedes of Dryopteris in Korea.

  • As a subset study to discover indigenous prokaryotic species in Korea, a total of 42 bacterial strains assigned to the class Alphaproteobacteria were isolated from diverse environmental habitats including plant roots, ginseng soil, forest soil, marsh, mud flat, freshwater, and seawater. From the high 16S rRNA gene sequence similarity (>99.1%) and formation of a robust phylogenetic clade with the closest species, it was determined that each strain belonged to each independent and predefined bacterial species. There is no official report that these 42 species have been described in Korea; therefore 4 species of 1 genera in the order Caulobacterales, 18 species of 10 genera in the order Rhizobiales, 7 species of 5 genera in the order Sphingomonadales and 13 species of 11 genera in the order Rhodobacterales within the Alphaproteobacteria are reported for alphaproteobacterial species found in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are also described in the species description section.

  • During a comprehensive investigation of indigenous prokaryotic species in Korea, a total of 46 bacterial strains assigned to the classes Alphaproteobacteria, Betaproteobacteria, Deltaproteobacteria, and Epsilonproteobacteria were isolated from a diversity of habitats including freshwater, seawater, brackish water, ginseng soil, plant roots, natural caves, and tidal flats. Based on their high 16S rRNA gene sequence similarities (>98.7%) and formation of strongly-supported phylogenetic clades with the closest type species, each strain was assigned to an independent, predefined bacterial species. Since there were no published or official reports regarding the isolation of these 46 species in Korea, here we report them as new species to Korea: 34 species in 14 families in the five orders of Alphaproteobacteria, 10 species in five families in the three orders of Betaproteobacteria, one species of Deltaproteobacteria and one species of Epsilonproteobacteria. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are described in the species description section.
