    ABSTRACT: Cilia are microtubule-based structures that project into the extracellular space. Ciliary defects are associated with several human diseases, including polycystic kidney disease, primary ciliary dyskinesia, left-right axis patterning, hydrocephalus and retinal degeneration. However, the genetic and cellular biological control of ciliogenesis remains poorly understood. The IFT46 is one of the highly conserved intraflagellar transport complex B proteins. In zebrafish, ift46 is expressed in various ciliated tissues such as Kupffer's vesicle, pronephric ducts, ears and spinal cord. We show that ift46 is localized to the basal body. Knockdown of ift46 gene results in multiple phenotypes associated with various ciliopathies including kidney cysts, pericardial edema and ventral axis curvature. In ift46 morphants, cilia in kidney and spinal canal are shortened and abnormal. Similar ciliary defects are observed in otic vesicles, lateral line hair cells, olfactory pits, but not in Kupffer's vesicle. To explore the functions of Ift46 during mouse development, we have generated Ift46 knock-out mice. The Ift46 mutants have developmental defects in brain, neural tube and heart. In particular Ift46(-/-) homozygotes displays randomization of the embryo heart looping, which is a hallmark of defective left-right (L/R) axis patterning. Taken together, our results demonstrated that IFT46 has an essential role in vertebrate ciliary development. Copyright © 2015 Elsevier Inc. All rights reserved.

    ABSTRACT: Insects impact human health through vector-borne diseases and cause major economic losses by damaging crops and stored agricultural products. Insect-specific growth regulators represent attractive control agents because of their safety to the environment and humans. We identified plant compounds that serve as juvenile hormone antagonists (PJHANs). Using the yeast two-hybrid system transformed with the mosquito JH receptor as a reporter system, we demonstrate that PJHANs affect the JH receptor, methoprene-tolerant (Met), by disrupting its complex with CYCLE or FISC, formation of which is required for mediating JH action. We isolated five diterpene secondary metabolites with JH antagonist activity from two plants: Lindera erythrocarpa and Solidago serotina. They are effective in causing mortality of mosquito larvae at relatively low LD50 values. Topical application of two diterpenes caused reduction in the expression of Met target genes and retardation of follicle development in mosquito ovaries. Hence, the newly discovered PJHANs may lead to development of a new class of safe and effective pesticides.

    ABSTRACT: A novel, Gram-stain positive, facultative anaerobic, non-motile and straight to curve rod shaped bacterium, strain LV19(T) was isolated from the larval gut of the rhinoceros beetle, Trypoxylus dichotomus, which was collected from Yeong-dong, Chuncheongbuk-do, South Korea. The colonies of the new isolate were convex, circular, cream white in color and 1-2 mm in diameter after 3 days incubation on Tryptic Soy Agar at 37 °C. Based on the 16S rRNA gene sequence similarity, the new isolate was most closely related to Erysipelothrix inopinata MF-EP02(T), E. rhusiopathiae ATCC 19414 (T) and E. tonsillarum T-305(T) (94.8, 93.8 and 93.7 % similarity, respectively). Strain LV19(T) grew optimally at 37 °C, at pH 8.0 and in the presence of 0.5 % (w/v) NaCl. Oxidase activity and catalase activity were negative. The major cellular fatty acids (>10 %) were C18:2 cis-9,12 (28.9 %), C18:1 cis-9 (22.3 %), C16:0 (22.2 %) and C18:0 (18.5 %). The cell-wall hydrolysates contained ribose as a major sugar. Major polar lipids were phosphatidylglycerol and three unidentified glycolipids. No quinone was detected. The G+C content of the genomic DNA was 36.3 mol%. The levels of DNA-DNA relatedness between strain LV19(T) and all the reference strains were less than 20 %. On the basis of polyphasic evidence from this study, the isolate is considered to represent a novel species of the genus Erysipelothrix, for which the name Erysipelothrix larvae sp. nov. is proposed; the type strain is LV19(T) (=KCTC 33523(T) = DSM 28480(T)).

    ABSTRACT: Clusterin, a protein associated with multiple functions, is expressed in a wide variety of tissues. Although clusterin is known to be involved in neurodegenerative diseases, ageing, and tumorigenesis, a detailed analysis of the consequences of gain- or loss-of-function approaches has yet to be performed to understand the underlying mechanisms of clusterin functions. Since clusterin levels change in neurological diseases, it is likely that clusterin contributes to cell death and degeneration in general. Zebrafish was investigated as a model system to study human diseases. During development, zebrafish clusterin was expressed in the notochord and nervous system. Embryonic overexpression of clusterin by mRNA microinjection did not affect axis formation, whereas its knock-down by anti-sense morpholino treatment resulted in neuronal cell death. To analyze the function of clusterin in neurodegeneration, a transgenic zebrafish was investigated, in which nitroreductase expression is regulated under the control of a neuron-specific huC promoter which is active between the stages of early neuronal precursors and mature neurons. Nitroreductase turns metronidazole into a cytotoxic agent that induces cell death within 12 h. After metronidazole treatment, transgenic zebrafish showed neuron-specific cell death. Interestingly, we also observed a dramatic induction of clusterin expression in the brain and spinal cord in these fish, suggesting a direct or indirect role of clusterin in neuronal cell death and thus, more generally, in neurodegeneration.

    ABSTRACT: A novel bacterium, designated strain 13-2-B6(T), was isolated from seawater adjacent to Songak Mountain on Jeju Island, South Korea. The novel strain was observed to be Gram-negative, aerobic, rod-shaped and motile with a single polar flagellum. On the basis of 16S rRNA gene sequence similarity, strain 13-2-B6(T) was determined to be phylogenetically closely related to the type strain of Antarctobacter heliothermus, currently the sole species of the genus Antarctobacter (family Rhodobacteraceae). Sequence similarity between the 16S rRNA genes of strain 13-2-B6(T) and A. heliothermus EL-219(T) is 96.9 %. Strain 13-2-B6(T) was found to grow optimally at 25-30 °C, pH 7.0-8.0 and 3 % (w/v) NaCl. The predominant isoprenoid quinone in strain 13-2-B6(T) was identified as ubiquinone Q-10 and the major fatty acids were identified as C18:1 ω7c and/or C18:1 ω6c. Phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, two unknown aminolipids, two unknown phospholipids, an unknown glycolipid and an unknown lipid were found to be components of the polar lipid profile. The G + C content of strain 13-2-B6(T) was determined to be 62 mol %. On the basis of its phenotypic, chemotaxonomic and phylogenetic distinctiveness, strain 13-2-B6(T) is considered to represent a novel species of the genus Antarctobacter, for which the name Antarctobacter jejuensis sp. nov. is proposed. The type strain is 13-2-B6(T) (=KCTC 42009(T) =JCM 19898(T)).

    ABSTRACT: Habitat changes of butterflies are caused by various factors, including food plants, natural enemies, and climate change. Recently, new habitats of the large copper have been reported on the Korean Peninsula, mostly along a riverside. This implies that this butterfly may move along a drainage system. In this study, new habitats of the large copper along the Geum River were investigated and the population dynamics of the butterfly were monitored in selected areas through the mark–release–recapture method. The results showed that the large copper had dispersed inland along the Geum River, which runs along the central western seashore of South Korea. In addition, the habitat distribution of the butterfly showed good coincidence with the distribution of a sorrel, Rumex japonicas, the main food plant of the large copper. A study on the moving distance of the butterfly showed that females moved further than males, while males showed more frequent movement within a short distance. The movement of the large copper along the Gum River, which lies over 100 km south of the Han River (a habitat previously reported in 1973), suggests that the movement of the butterfly might be more affected by human activities, such as the development of bike paths along the Gum River and maintenance of the riverbed, than climate change.

    ABSTRACT: A novel strain, designated W-15T, was isolated from the gut of the long-horned beetle, Massicus raddei, collected in South Korea. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the strains belonged to the suborder Micrococcineae. The strain W-15T was most closely related to Luteimicrobium album RI148-Li105T (97.9% similarity). Strain W-15T was Gram- positive, rod and coccus shaped, non-motile. Growth was observed at 15-37 °C, at pH 4.5-8.5 and in the presence of 0-5.0% NaCl. The cell-wall peptidoglycan of the strain was A4α (L-Lys-D-Ser-D-Asp). The major menaquinone present in this strain was MK-8 (H2) and the major cellular fatty acids were anteiso-C15:0, iso-C16:0, iso-C15:0 and anteiso-C17:0. The major polar lipids were diphosphatidylglycerol, phosphatidylinositol, an unknown lipid an unknown phospholipid and an unknown phosphoglycolipid. The G+C content of genomic DNA of the strain was 73.8%. On the basis of evidence from our polyphasic taxonomic study, strain W-15T is classified within a novel genus and species in the suborder Micrococcineae, for which the name Luteimicrobium xylanilyticum sp. nov. is proposed. The type strain of this genus is strain W-15T (= KCTC 19882 T = JCM 18090 T).
