  • In this study, endophytic fungi were isolated from the leaves of evergreen woody plants in Hansando Island in South Korea. The fungal isolates were identified based on morphological characteristics and phylogenetic analysis of the DNA sequences of the internal transcribed spacer and the large subunit regions of rDNA. It was confirmed that two endophytic fungal species, Muyocopron lithocarpi and Didymocyrtis cladoniicola, isolated in this study have not previously been reported in South Korea.

  • We isolated endophytic fungi from the roots of Quercus spp. in Korea. The isolates were identified based on morphological and molecular characteristics from the nucleotide sequences of the internal transcribed spacer and large subunit of rDNA regions. We confirmed that the four species we isolated - Oidiodendron citrinum, Acremonium crotocinigenum, Mammaria echinobotryoides, and Pleotrichocladium opacum - have not been recorded previously in Korea. Herein, we present their morphological characteristics and the result of phylogenetic analysis.

  • The genus Pseudoperonospora, an obligate biotrophic group of Oomycota, causes the most destructive foliar downy mildew disease on many economically important crops and wild plants. A previously unreported disease by Pseudoperonospora was found on oriental pickling melon (Cucumis melo var. conomon) in Korea, which is a minor crop cultivated in the temperate climate zone of East Asia, including China, Korea, and Japan. Based on molecular phylogenetic and morphological analyses, the causal agent was identified as Pseudoperonospora cubensis, and its pathogenicity has been proven. Importantly, two phylogenetic clades of P. cubensis, harboring probably two distinct species, were detected within the same plots, suggesting simultaneous coexistence of the two clades. This is the first report of P. cubensis causing downy mildew on oriental pickling melon in Korea, and the confirmation of presence of two phylogenetic clades of this pathogen in Korea. Given the high incidence of P. cubensis and high susceptibility of oriental pickling melon to this disease, phytosanitary measures, including rapid diagnosis and effective control management, are urgently required.

  • In July 2023, previously unrecorded fungi belonging to the genus Helvella were collected from the city of Taebaek, South Korea. These fungi are morphologically similar to Helvella crispa, but their differences include a wide, saddle-shaped apothecium and white hair on the receptacle surface. By analyzing DNA sequences combining the internal transcribed spacer (ITS) and nuclear ribosomal large subunit (nrLSU) regions and comparing them with various related species of Helvella, the collected fungi were identified as H. orienticrispa.

  • Fourteen bacterial strains, low10-4-1, J11015, 17J27-22, 17G22-9, 17G9-4, 17Bio_15, 17gy_33, 17SD1_21, Strain8, 17Sr1_17, J21014T, H31021, 17J49-9, and 17J80-6 assigned to the phylum Actinobacteria, Bacteroidetes, Deinococcus-Thermus, and Firmicutes were isolated from soil samples. Phylogenetic analysis based on 16S rRNA gene sequence revealed that strains low10-4-1, J11015, 17J27-22, 17G22-9, 17G9-4, 17Bio_15, 17gy_33, 17SD1_21, Strain8, 17Sr1_17, J21014T, H31021, 17J49-9, and 17J80-6 were most closely related to Marmoricola aurantiacus (98.9%), Calidifontibacter indicus (99.8%), Gordonia soli (98.8%), Rhodococcus globerulus (99.5%), Pseudarthrobacter siccitolerans (99.1%), Hymenobacter qilianensis (98.7%), Hymenobacter terrae (99.0%), Deinococcus yunweiensis (99.2%), Deinococcus proteolyticus (99.7%), Domibacillus indicus (99.2%), Exiguobacterium mexicanum (100.0%), Kurthia senegalensis (99.1%), Lysinibacillus composti (99.6%), and Bacillus loiseleuriae (99.3%). These fourteen species have never been reported in Korea, therefore we report them here for the first time.

  • In this study, bacterial communities within the guts of several longicorn beetles were investigated by a culture-dependent method. A total of 142 bacterial strains were isolated from nine species of longicorn beetle, including adults and larvae. A comparison of their partial 16S rRNA gene sequences showed that most of the bacteria constituting the gut communities can typically be found in soil, plants and the intestines of animals, and approximately 10% were proposed as unreported. Phylogenetic analysis demonstrated that the bacterial species comprised 7 phyla, and approximately half were Gammaproteobacteria. Actinobacteria were the second most populous group (19%), followed by Firmicutes (13%) and Alphaproteobacteria (11%). Betaproteobacteria, Flavobacteria, and Acidobacteria were minor constituents. The taxonomic compositions of the isolates were variable according to the species of longicorn beetle. Particularly, an abundance of Actinobacteria existed in Moechotypa diphysis and Mesosa hirsute, which eat broadleaf trees; however, no Actinobacteria were isolated from Corymbia rubra and Monochamus alternatus, which are needle-leaf eaters. Considerable proportions of xylanase and pectinase producing bacteria in the guts of the longicorn beetles implied that the bacteria may play an important role in the digestion of woody diets. Actinobacteria and Gammaproteobacteria were the dominant xylanase producers in the guts of the beetles.

  • Eight bacterial strains, 18JY8-13, 18JY13-16, 18JY43-7, 18JY12-7, 18JY1-1, 18JY1-7, 18JY15-3, and 18JY7-2 assigned to the phylum Firmicutes were isolated from a variety of soil samples collected in the Jeju Island, Korea. Cells of the eight strains were Gram-positive, aerobic and showed resistant to UV-radiation. Phylogenetic analysis based on 16S rRNA gene sequence revealed that strains 18JY8-13, 18JY13-16, 18JY43-7, 18JY12-7, 18JY1-1, 18JY1-7, 18JY15-3, and 18JY7-2 were most closely related to Bacillus paranthracis(99.9%), Bacillus paramycoides(99.6%), Bacillus australimaris(99.9%), Bacillus wiedmannii (100%), Bacillus halosaccharovorans(99.6%), Bacillus deserti(98.7%), Bacillus cereus (99.8%), and Bacillus albus(100%), respectively. This is the first report of these eight species in Korea.
