  • The RAD4 gene of Saccharomyces cerevisiae is essential for the incision step of UV-induced excision repair. A yeast RAD4 gene has been previously isolated by functional complementation. In order to identify the RAD4 homologous gene from fungus Coprinus cinereus, we have constructed cosmid libraries from electrophoretically separated chromosomes of the C. cinereus. The 13 C. cinereus chromosomes were resolved by pulse-field gel electrophoresis, hybridized with S. cerevisiae RAD4 DNA, and then isolated homologous C. cinereus chromosome. The insert DNA of the RAD4 homolog was contained 3.2 kb. Here, we report the characterization of fungus C. cinereus homolog of yeast RAD4 gene. Southern blot analysis confirmed that C. cinereus contains the RAD4 homolog gene and this gene exists as a single copy in C. cinereus genome. When total RNA isolated from C. cinereus cells was hybridized with the 1.2 kb PvuII DNA fragment of the S. cerevisiae RAD4 gene, a 2.5 kb of transcript was detected. In order to investigation whether the increase of transcripts by DNA damaging agent, transcripts levels were examined after treating the cells. The level of transcript did not increase by untraviolet light (UV). This result indicated that the RAD4 homologous gene is not UV inducible gene. Gene deletion experiments indicate that the RAD4 homologous gene is essential for cell viability.

  • Higher fungi were collected in Mt. Jiri National Park areas from May, 1987 to October, 1987. These higher fungi were identified. As a result of identification, Conocybe rickenii (Schaeffer) Kuhner, Coprinus rhizophorus kawam et al., Agaricus comtulus Fr., Tricholomopsis decora (Fr.) Sing., Gymnopilus penetrans (Fr. ex Fr.) Murr., Amanita abrupta Peck, A. rufoferruginea Hongo and Stropharia semiglobata (Batsch ex Fr.) Quel. were newly recorded in Korea.

  • Through a floral study and resource investigation of Korean mushrooms during the year 1993, five species of Agaricales, Pseudoclitocybe cyathiformis (Bull.: Fr.) Sing.; Pholiota brunnescens A.H. Smith & K. Hesler; Coprinus angulatus Peck; Rhodophyllus bisporus Hongo; Suillus viscidipes Hongo and one form of Gasteromycetes, Lysurus mokusin (L.: Pers.) Fr.f. sinensis (Lloyd) Kobayashi, were found and described new to Korean flora. Pseudoclitocybe is described as an unrecorded genus to Korea. The color names cited are from Kornerup & Wanscher's Methuen Handbook of Colour (1984). All the specimens are deposited in the RDAGB's and ASIK's herbarium.

  • To investigate the fungal diversity in Mt. Paekwoon, higher fungi were collected in July, 1991 from the two locations of Seoul National University Forests in Kwangyang-gun, Chonnam Province. A total of 137 fungal species were collected and classified. Following six species were identified as new species unrecorded in Korea. Their morphological and taxonomic features including microscopic characteristics of spores and cystidia were also reported in this paper. Marasmius pulcherripes Peck ; Agaricus purpurellus(Moller) Moller ; Coprinus echinosporus Buller ; Xerocomus nigromaculatus Hongo ; Boletellus shichianus(Teng & Ling) Teng ; Russula kansaiensis Hongo.

  • Two fractions with unusual antifungal activity that suppress asexual sporulation of several fungi were obtained from culture filtrate of Pseudomonas aeruginosa and were partially purified through the repeated silicagel flash column chromatographies. The sporulation-suppressive actions of these fractions in Aspergillus nidulans, Rhizopus stolonifer, and Coprinus cinereus, were analyzed by light and electron microscopes. The germination ability of the spores produced in the presence of these fractions were also checked to determine the persistent effects of these antifungal substances on the next generation. Light microscopic observation of developing sporangia of R. stolonifer grown in the presence of both fractions revealed that the significant number of sporangia failed to reach maturity, and frequently, uncontrolled growths of hyphae and rhizoids from the sporangiophores were found. In A. nidulans addition of these fractions appeared to cause different classes of morphological abnormality in conidia development, which included aborted formation of conidiogenous cells from the apex of conidiophores and enhanced hyphal growths either at the tip or middle of the conidiophores. Germination abilities of spores obtained from the cultures grown in the presence of antifungal fractions were 40∼60% in Aspergillus, 50∼80% in Coprinus (thallic spores), and 30∼40% in Rhizopus compared to those of normal spores.

  • Alkaline cellulolytic enzymes from cultured medium of Coprinus cinereus 2249 were purified with gel and ion-exchange chromatography and characteristics of those enzyme proteins were investigated. A fiber length distribution and a crystallinity of cellulose and sugar composition of enzyme treated Mixed Office Wastepaper(MOW) and Unbleached Kraft Pulp(UKP) were analysed. The conclusion could summarized as follows; \circled1 Alkaline and acidic, endo- and exo-glucanases were purified from cultured medium of Coprinus cinereus 2249. \circled2 The approximate molecular weight of alkaline endo-glucanase was 42 kDa, and also that of alkaline exo-glucanase was 50 kDa. A fiber length distribution and a crystallization of cellulose and sugar composition of enzyme treated MOW and UKP were not so much changed with original paper and pulp.
