  • We prepared supernatants and cell-free extracts of yeasts isolated from wild flowers in Korea, and their antioxidant activity and inhibitory activities of xanthine oxidase and tyrosinase were investigated. Among them, cell-free extracts of Kuraishia capsulata UL40-2 and Sporobolomyces ruberrimus 121-Z-3 showed significantly high xanthine oxidase inhibitory activity of 46.4% and 48.3%, respectively. Starmerella bombicola 80-J-1 also showed tyrosinase inhibitory activity of 36.2% in the cell-free extract. Other antioxidant activities and tyrosinase inhibitory activities were not detected or were below 20%. Maximal production of the xanthine oxidase inhibitors were observed when Kuraishia capsulate UL40-2 and Sporobolomyces ruberrimus 121-Z-3 were cultured in the yeast extract-peptone-dextrose media at $30^{\circ}C$ for 24 hour, respectively.

  • To develope wild flower collected from Chollabuk-do area resource plant species were investigated from May 1996 to April 1997. This study was focussed to make the basic data for better quality of breeding species from wild flower species and to keep proper gene pool for development with competitive power internationally in future. There was 131 species blooming in spring season(34.7%), 219 species in summer(58.1%), 25 species in autumn(6.6%) and 2 species in winter(0.5%), respectively. Flower color of all the plants was 26 kinds in diverse, among them, white flowers were occupied dominantly of 28.9%, yellow flowers, 20.7%, violet flowers, 16.4% and red purple flowers, 7.9%, respectively. Transplanted wild flower plants at the garden in the study area frequently were Chelidonium majus var. asiaticum, Hemerocallis fulva, Iris nertschinskia, Rhododendron yedoense var. poukhanense, Rhododendron mucronulatum, Pulsatilla koreana, Chrysanthemum zawadskii var. latilobum, Taraxacum platycarpum, Chrysanthemum boreale, Liriope platyphylla and Lycoris radiata. Twenty-six species of wild flowers such as Cymbidium goeringii, H. fulva, L. radiata, C. zawadskii var. latilobum, etc. were collected from their habitat and being selling at the market or road side. Total 343 taxa of wild flowers to prevent carrying out to foreign countries and to improve better quality were selected and recommended in this study, for example, they were 41 taxa of Compositae plant, 25 of Rosaceae, 20 of Liliaceae and 18 of Ranunculaceae in order. Acorus calamus var. angustatus, Cypripedium japonicum, C. macranthum, Calanthe discolor, Dicentra spectabilis, Ilex cornuta, Stewartia koreana, Abeliophyllum distichum, Forsythia saxatilis and Campanula glomerata var. dahurica should be protected as wild flowers because their numbers are decreasing remarkably, belong to rare species, being at a crisis to extinct species and important plants for research materials.

  • 희귀식물은 야생화 애호가의 선망의 대상이다. 희귀식물을 찾기 위한 애로호가들의 활동은 참으로 열성적이다. 그런데 희귀동식물은 단순히 희귀성을 쫓는 사람들에게만 중요한 존재가 아니다. 희귀식물은 미래의 자원으로서 활용가치가 뛰어나기 때문에 국가 차원의 보호노력이 요구된다. 특히 우리만이 가지고 있는 자원이라면 그 상대적 활용가치는 무궁무진하다. 세계 여러 나라가 생물다양성협약에 주목하는 이유이기도 하다.

  • Sporulation in the fission yeast Schizosaccharomyces pombe has been regarded as an important model of cellular development and differentiation. S. pombe cells proliferate by mitosis and binary fission on growth medium. Deprivation of nutrients especially nitrogen sources, causes the cessation of mitosis and initiates sexual reproduction by matting between two sexually compatible cell types. Meiosis is then followed in a diploid cell in the absence of nitrogen source. DNA fragment complemented with the mutations of sporulation gene was isolated from the S. pombe gene library constructed in the vector, pDB 248' and designated as pDB(spo5)1. We futher analyzed six recombinant plasmids, pDB(spo5)2, pDB(spo5)3, pDB(spo5)4, pDB(spo5)5, pDB (spo5)6, pDB(spo5)7 and found each of these plasmids is able to rescue the spo5-2, spo5-3, spo5-4, spo5-5, spo5-6, spo5-7 mutations, respectively. Mapping of the integrated plasmid into the homologous site of the S. pombe chromosomes demonstrated that pDB(spo5)1, and pDB(spu5)Rl contained the spo5 gene. Transcripts of spo5 gene were analyzed by Northern hybridization. Two transcripts of 3.2 kb and 2.5kb were detected with 5kb Hind Ⅲ fragment containing a part of the spo5 gene as a probe. The small mRNA(2.5kb) appeared only when a wild-type strain was cultured in the absence of nitrogen source in which condition the large mRNA (3.2kb) was produced constitutively. Appearance of a 2.5kb spo5-mRNA depends upon the function of the meil, mei2 and mei3 genes.

  • This study focused on isolation of wild yeasts from natural flowers and elucidation of yeast diversity. Wild yeasts were isolated from various flowers collected from mountains on the islands including Jejudo, Ulleungdo, Yokjido, and Seonyudo as well as inlands including Gyejoksan, Oseosan, Beakamsan, and Deogyusan in Korea. Isolated yeasts were identified by comparison of nucleotide sequences for polymerrase chain reaction-amplified D1/D2 region of 26S rDNA or internal transcribed spacer 1 and 2 including 5.8S rDNA using BLAST. 289 strains belonging to 134 yeast species were isolated. Cryptococcus genus strains were the most frequently isolated species among the identified yeasts. Metschnikowia reukaufii was also frequently isolated. Twenty three species including Cryptococcus aureus were overlapped between those of mountains on islands and inland. Physiological functionalities such as antioxidant activity, xanthine oxidase inhibitory activity, and tyrosinase inhibitory activity for the 289 identified yeast strains were investigated using their supernatant and cell-free extracts. The supernatants of Candida sp. 78-J-2 and Metschnikowia reukaufii SY44-6 showed antioxidant activity of 22.5%, and anti-gout xanthine oxidase inhibitory activity of 49.6%, respectively.

  • Several yeasts were isolated from flowers found in Gyonggi-do Province and Jeju island in Korea. They were then identified by a comparison of their PCR-amplified D1/D2 regions of 26S rDNA, internal transcribed spacer 1 and 2 inclusive of 5.8S rDNA, using the BLAST database. A total of fifty four yeast strains were isolated from wild flowers in Gyonggi-do and the genus Pseudozyma was noted as being dominant. A total of thirty two strains were isolated from Songaksan and Seongsan-ilchulbong in Jeju island and Sporobolomyces ruberrimus was seen to be dominant. The anti-gout xanthine oxidase inhibitory activities of the culture broths and cell-free extracts from eighty six yeast strains were then determined. The cell-free extracts of Pseudozyma hubeiensis 228-S-1 exhibited the highest xanthine oxidase inhibitory activity of 19.6%. The XOD inhibitor was also maximally produced when Pseudozyma hubeiensis 228-S-1 was cultured at $30^{\circ}C$ for 36h in YEPD medium.

  • Several kinds of yeasts were isolated from wild flowers collected from Muju resort of Deogyu mountain in Korea and identified by comparison of nucleotide sequences of D1/D2 region of 26S rDNA using BLAST. Totally twenty-two strains of eight species were isolated and Cryptococcus magnus (9 strains) and Cryptococcus flavescenes (6 strains) were dominant species. The supernatant and cell-free extracts were prepared and their antioxidant activity, anti-gout xanthine oxidase inhibitory activity and whitening tyrosinase inhibitory activity were investigated. Anti-gout xanthine oxidase inhibitory activities of Sporobolomyces phaffii JS00583 and Rhodotorula graminis JS00581 were 40.4% and 39.1%, respectively and also was 36.1% whitening tyrosinase inhibitory activity in the supernatant of Cryptococcus magnus JS00570.
