  • Korean folk medicine 'Mul Bong Seon' has been used to cure hypertension and a toxicide. The botanical origin of the crude drug has been no pharmacognostical confirmation on it. To clarify the botanical origin of 'Mul Bong Seon', the morphologial and anatomical characteristics of the leaves of Impatiens species growing in Korea, i.e. I. balsamina, I. noli-tangere, I. textori, I. textori forma. pallescens were studied. As a result, it was clarified that 'Mul Bong Seon' was the leaf of Impatiens textori and Impatiens textori forma. pallescens.

  • Korean folk medicine 'Man Byung Cho' has been used to cure abdominal pain, athlete's foot and neuralgia. The botanical origin of the crude drug has never been studied pharmacognostically. To clarify the botanical origin of 'Man Byung Cho', the leaf morphology and anatomy were examined for the Korean species of Rhododendron subgenus Hymenanthes, such as R. brachycarpum G. Don, R. brachycarpum var. rosueum Koidz. and R. aureum Georgi. The study shows that 'Man Byung Cho' is the leaf of R. brachycarpum and R. brachycarpum var. roseum.

  • The Korean folk medicine 'Am Cho' has been used as the folk remedy for diuretic, stomach and liver cancer. The botanical origin of the crude drug has not been studied pharmacognostically. To clarify the botanical origin of 'Am Cho', the comparative morphological and anatomical characteristics have been studied of Lepisorus species growing wild in Korea, i.e. L. annuifrons, L. onoei, L. thunbergianus, L. ussuriensis and 'Am Cho' form Korea. As a result, it was clarified that 'Am Cho' from Korea was derived from Lepisorus onoei.

  • Korean folk medicine 'Ki Rin Cho' has been used to cure stanching and counteracting poison. The botanical origin of the crude drug has never been studied pharmacognostically. To clarify the botanical origin of 'Ki Rin Cho', the morphological and anatomical characteristics of Sedum species growing in Korea, i.e. S. aizoon, S. kamtschaticum and S. latiovalifolium were studied. As a result, 'Ki Rin Cho' was proved to be Sedum kamtschaticum and Sedum aizoon.

  • Chromosome number, morphological variation and RAPD analysis were investigated to study on the speciation of Indigofera in Korea. Chromosome numbers of I. kirilowii (2n=16) and I. koreana (2n=32) are consistent with the previous reports. In this study tetraploid (2n=32) and hexaploid (2n=48) of I. grandiflora are newly observed. Indigofera grandiflora is distributed around Mt. Kaya area together with I. kirilowii and I. koreana. The former species has the larger sizes in plant height, leaves and flowers than the latter two and shows intermediate form between the two species in hairs on leaves and flowers which are one of the most important taxonomic characters in this group. In the RAPD analysis, I. grandiflora is similar to I. koreana than I. kirilowii but RAPD band patterns revealed difference between tetra- and hexaploid of the species. These results suggested that Korean endemic species of I. grandiflora (2n=16, 32, 48) might has multiple origin through polyploidization and/or hybridization between I. kirilowii (2n=16) and I. koreana (2n=32) around Mt. Kaya area where the latter two grow together.

  • According to our previous study, 500 species of yeast exist in Korea, including nine variants comprising 142 genera and 48 classes in two phyla. Additionally, 4,483 fungal species have been documented at the National Institute of Biological Resources (NIBR). However, despite the industrial use of several yeasts, only 173 species formed part of the National Species List of Korea (NSLK) as of December 2021, mainly due to the lack of taxonomic descriptions. This study aimed to investigate the taxonomy of seven newly isolated yeast species (Hyphopichia burtonii, Starmerella sorbosivorans, Cyberlindnera mycetangii, Cutaneotrichosporon oleaginosum, Nakazawaea ernobii, Pichia kudriavzevii, and Schizosaccharomyces japonicus) for inclusion in the NSLK. The strains were clustered for the phylogenetic analysis of fungal rDNA (D1/D2-26S) sequences. This study provides descriptions of their cell morphology and physiological characteristics, the results of which confirm the indigenous origin of these seven species in Korea and recommend their inclusion in the NSLK.

  • In recent years, the knowledge about bifidobacteria has considerably evolved thanks to recent progress in molecular biology. The analysis of the whole genome sequences of 48 taxa of bifidobacteria offers new perspectives for their classification, especially to set up limit between two species. Indeed, several species are presenting a high homology and should be reclassified. On the other hand, some subspecies are presenting a low homology and should therefore be reclassified into different species. In addition, a better knowledge of the genome of bifidobacteria allows a better understanding of the mechanisms involved in complex carbohydrate metabolism. The genome of some species of bifidobacteria from human but also from animal origin demonstrates high presence in genes involved in the metabolism of complex oligosaccharides. Those species should be further tested to confirm their potential to metabolize complex oligosaccharides in vitro and in vivo.

  • Comparative morphology of winter buds of 16 species of gymnosperms which belong to six families and 13 genera was investigated. All the species examined except Taxaceae had bracts and ovuliferous scales in female buds, and the bract was fused with ovuliferous scale in various degrees. Comparison of the modern conifers with fossil ones in the position of ovule and structure of bract-scale complex suggested that Taxaceae should be placed in Coniferales, rather than treating as a distinct order. The disposition of bract surrounding the ovules of Cephalotaxus and Torreya indicated that the origin, of ovules had separate evolutionary line in spite of similar structure of female bud. The shape of microsporophyll in male bud was diverse among the species. The dehiscence of microsporangium was transverse in Abies and Tsuga, while longitudinal in other species. Descriptions and key to the species based on bud morphology were provided.
