HMG1 proteins from evolutionary distant organisms distort B-DNA conformation in similar way. (1/233)

The abundant high-mobility group proteins 1/2 (HMG1/2) represent a group of potent architectural elements of chromatin. They are able to induce strong bends and untwist DNA. Here, we compared the abilities of diverse HMG1 proteins to distort the B-DNA conformation of 30-base pair DNA fragment. The DNA bending was measured in solution by monitoring fluorescence resonance energy transfer between fluorescence probes attached to opposite ends of the DNA fragment. Various insect and plant proteins which differ in size, in composition of their HMG1-box domains (HMG1-BD), and in composition of the N- and the C-terminally flanking regions were analyzed in these experiments. Despite these structural differences the extent of the induced changes in DNA conformation upon binding to various proteins was similar, as the estimated bend angle was 150+/-20 degrees for all the tested proteins. Our results suggest that a set of highly conserved residues stabilizing the tertiary structure of the HMG1-BD mainly determines the extent of DNA bending in the complex. Even extended positively charged regions flanking the HMG1-BD are apparently not able to influence this conformational distortion of DNA.  (+info)

Identification of Chironomus kiiensis allergens, a dominant species of non-biting midges in Korea. (2/233)

Non-biting midges are known to contain potent inhalant allergens. IgE antibody responses to the crude extract of Chironomus kiiensis adults, a dominant chironomid species in Korea, were examined. With the IgE-ELISA or passive cutaneous anaphylaxis reactions, increased levels of chironomid-specific IgE were detected in the skin test positive human sera, or immunized BALB/c mouse sera with the crude extract adsorbed to alum. IgE-immunoblot analysis showed major IgE-reacting protein band patterns, which reacted with more than 50% of the skin test positive human sera, at 110, 80, 73, 46, 40, 37, 34, and 31 kDa. The reactive band patterns were largely similar between skin test positive humans and immune BALB/c mice. However, the bands of 55, 31, 27, 26, 24, and 23 kDa were found only in sensitized humans, but not in immunized mice.  (+info)

Electron tomography reveals posttranscriptional binding of pre-mRNPs to specific fibers in the nucleoplasm. (3/233)

Using electron tomography, we have analyzed whether the Balbiani ring (BR) pre-mRNP particles in transit from the gene to the nuclear pore complex (NPC) are bound to any structure that could impair free diffusion through the nucleoplasm. We show that one-third of the BR particles are in contact with thin connecting fibers (CFs), which in some cases merge into large fibrogranular clusters. The CFs have a specific protein composition different from that of BR particles, as shown by immuno-EM. Moreover, we have identified hrp65 as one of the protein components of the CFs. The sequencing of hrp65 cDNA reveals similarities with hnRNP proteins and splicing factors. However, hrp65 is likely to have a different function because it does not bind to nascent pre-mRNA and is not part of the pre-mRNP itself. Taken together, our observations indicate that pre-mRNPs are not always freely diffusible in the nucleoplasm but interact with fibers of specific structure and composition, which implies that some of the posttranscriptional events that the pre-mRNPs undergo before reaching the NPC occur in a bound state.  (+info)

The Ct-RAE1 protein interacts with Balbiani ring RNP particles at the nuclear pore. (4/233)

RAE1 is an evolutionarily conserved protein that associates with both mRNPs and nucleoporins, and may bridge the interaction between mRNP export cargoes and the nuclear pore complex (NPC). However, the mechanism by which RAE1 functions in mRNA export is still unknown and the time point at which RAE1 interacts with the exported RNP has not been directly investigated. Here we have addressed this question in the Balbiani ring (BR) system of Chironomus tentans using immunoelectron microscopy. The RAE1 protein of C. tentans, Ct-RAE1, is 70% identical to human RAE1/mrnp41 (hRAE1) and is recognized by antibodies raised against hRAE1. As in vertebrate cells, Ct-RAE1 is concentrated at the nuclear envelope and also dispersed throughout the nuclear interior. Here we show that Ct-RAE1 does not bind to the BR particle either cotranscriptionally or in the nucleoplasm. Instead, the interaction between Ct-RAE1 and the exported BR particle occurs at the NPC. Moreover, the localization of Ct-RAE1 at the NPC is correlated with the presence of an exported RNP in the NPC. Finally, the anti-RAE1 antibody does not label the cytoplasmic side of BR particles in transit through the central channel, which indicates that Ct-RAE1 either remains anchored at the nuclear side of the NPC during translocation of the RNP through the central channel or becomes transiently associated with the RNP but is rapidly released into the cytoplasm.  (+info)

Actin bound to the heterogeneous nuclear ribonucleoprotein hrp36 is associated with Balbiani ring mRNA from the gene to polysomes. (5/233)

In the salivary glands of the dipteran Chironomus tentans, a specific messenger ribonucleoprotein (mRNP) particle, the Balbiani ring (BR) granule, can be visualized during its assembly on the gene and during its nucleocytoplasmic transport. We now show with immunoelectron microscopy that actin becomes associated with the BR particle concomitantly with transcription and is present in the particle in the nucleoplasm. DNase I affinity chromatography experiments with extracts from tissue culture cells indicate that both nuclear and cytoplasmic actin are bound to the heterogeneous RNP (hnRNP) protein hrp36, but not to the hnRNP proteins hrp23 and hrp45. The interaction is likely to be direct as purified actin binds to recombinant hrp36 in vitro. Furthermore, it is demonstrated by cross linking that nuclear as well as cytoplasmic actin are bound to hrp36 in vivo. It is known that hrp36 is added cotranscriptionally along the BR mRNA molecule and accompanies the RNA through the nuclear pores and into polysomes. We conclude that actin is likely to be bound to the BR transcript via hrp36 during the transfer of the mRNA from the gene all the way into polysomes.  (+info)

Consecutive steps of phosphorylation affect conformation and DNA binding of the chironomus high mobility group A protein. (6/233)

The high mobility group (HMG) proteins of the AT-hook family (HMGA) lie downstream in regulatory networks with protein kinase C, Cdc2 kinase, MAP kinase, and casein kinase 2 (CK2) as final effectors. In the cells of the midge Chironomus, almost all of the HMGA protein (cHMGA) is phosphorylated by CK2 at two adjacent sites. 40% of the protein population is additionally modified by MAP kinase. Using spectroscopic and protein footprinting techniques, we analyzed how individual and consecutive steps of phosphorylation change the conformation of an HMGA protein and affect its contacts with poly(dA-dT).poly(dA-dT) and a fragment of the interferon-beta promoter. We demonstrate that phosphorylation of cHMGA by CK2 alters its conformation and modulates its DNA binding properties such that a subsequent phosphorylation by Cdc2 kinase changes the organization of the protein-DNA complex. In contrast, consecutive phosphorylation by MAP kinase, which results in a dramatic change in cHMGA conformation, has no direct effect on the complex. Because the phosphorylation of the HMGA proteins attenuates binding affinity and reduces the extent of contacts between the DNA and protein, it is likely that this process mirrors the dynamics and diversity of regulatory processes in chromatin.  (+info)

In situ transcription and splicing in the Balbiani ring 3 gene. (7/233)

The Balbiani ring 3 (BR3) gene contains 38 introns, and more than half of them are co-transcriptionally excised. We have determined the in situ structure of the active BR3 gene by electron tomography. Each of the 20-25 nascent transcripts on the gene is present together with splicing factors and the RNA polymerase II in a nascent transcript and splicing complex, here called the NTS complex. The results indicate that extensive changes in overall shape, substructure and molecular mass take place repeatedly within an NTS complex as it moves along the gene. The volume and calculated mass of the NTS complexes show that, maximally, one complete spliceosome is assembled on the multi-intron transcript at any given time point. The structural data show that the spliceosome is not a structurally well-defined unit in situ and that the C-terminal domain of the elongating RNA polymerase II cannot carry spliceosomal components for all introns in the BR3 transcript. Our data indicate that spliceosomal factors are continuously added to and released from the NTS complexes during transcription elongation.  (+info)

Assembly and transport of a premessenger RNP particle. (8/233)

Salivary gland cells in the larvae of the dipteran Chironomus tentans offer unique possibilities to visualize the assembly and nucleocytoplasmic transport of a specific transcription product. Each nucleus harbors four giant polytene chromosomes, whose transcription sites are expanded, or puffed. On chromosome IV, there are two puffs of exceptional size, Balbiani ring (BR) 1 and BR 2. A BR gene is 35-40 kb, contains four short introns, and encodes a 1-MDa salivary polypeptide. The BR transcript is packed with proteins into a ribonucleoprotein (RNP) fibril that is folded into a compact ring-like structure. The completed RNP particle is released into the nucleoplasm and transported to the nuclear pore, where the RNP fibril is gradually unfolded and passes through the pore. On the cytoplasmic side, the exiting extended RNP fibril becomes engaged in protein synthesis and the ensuing polysome is anchored to the endoplasmic reticulum. Several of the BR particle proteins have been characterized, and their fate during the assembly and transport of the BR particle has been elucidated. The proteins studied are all added cotranscriptionally to the pre-mRNA molecule. The various proteins behave differently during RNA transport, and the flow pattern of each protein is related to the particular function of the protein. Because the cotranscriptional assembly of the pre-mRNP particle involves proteins functioning in the nucleus as well as proteins functioning in the cytoplasm, it is concluded that the fate of the mRNA molecule is determined to a considerable extent already at the gene level.  (+info)

In vertebrates, a nuclear cap-binding complex (CBC) formed by two cap- binding proteins, CBP20 and CBP80, is involved in several steps of RNA metabolism, including pre-mRNA splicing and nuclear export of some RNA polymerase II-transcribed U snRNAs. The CBC is highly conserved, and antibodies against human CBP20 cross-react with the CBP20 counterpart in the dipteran Chironomus tentans. Using immunoelectron microscopy, the in situ association of CBP20 with a specific pre-mRNP particle, the Balbiani ring particle, has been analyzed at different stages of pre-mRNA synthesis, maturation, and nucleo-cytoplasmic transport. We demonstrate that CBP20 binds to the nascent pre-mRNA shortly after transcription initiation, stays in the RNP particles after splicing has been completed, and remains attached to the 5 domain during translocation of the RNP through the nuclear pore complex (NPC). The rapid association of CBP20 with nascent RNA transcripts in situ is consistent with the role of CBC in splicing, ...

Balbiani ring (BR) granules are premessenger ribonucleoprotein particles (RNPs) generated in giant chromosomal puffs, the BRs, in the larval salivary glands of the dipteran chironomus tentans. Monoclonal antibodies were raised against nuclear proteins collected on a single-stranded-DNA-agarose affinity column, and two of them were used to identify RNA-binding proteins in BR granules. First, in Western blots (immunoblots), one of the antibodies recognized a 36-kDa protein and the other recognized a 45-KDa protein. Second, both antibodies bound to the BRs in immunocytological experiments. It was shown in cross-linking experiments that the two proteins are associated with heterogeneous nuclear RNP (hnRNP) complexes extracted from C. tentans nuclei. By immunoelectron microscopy of isolated and partly unfolded BR RNPs, it was specifically demonstrated that the BR granules contain the two proteins and, in addition, that both proteins are distributed frequently along the RNP fiber of the particles. ...

The base composition of DNA was determined for individual chromosomes from the dipteran Chironomus tentans and for each one of six different segments of one of the chromosomes. The isolations were carried out by micromanipulation and the DNA purines were first extracted from the isolated components and afterwards separated by means of microelectrophoresis on a cellulose fiber. It was found that DNA from this material has an unusual composition corresponding to a guanine + cytosine content of about 30%. This composition was not a function of the polytenic condition but was also found for DNA from testis tissue. Furthermore Drosophila has a more traditional base composition for the bulk of DNA. Statistically significant variations in base data were found between whole chromosomes as well as between the segments from one of the chromosomes.. ...

The potential of chironomid larvae-based metrics in the bioassessment of non-wadeable riversThe potential of chironomid larvae-based metrics in the bioassessment of non-wadeable rivers
The chironomid community in non-wadeable lotic systems was tested as a source of information in the construction of biological metrics which could be used into the bioassessment protocols of large rivers. In order to achieve this, we simultaneously patterned the chironomid community structure and environmental factors along the catchment of the Danube and Sava River. The Self organizing map (SOM) recognized and visualized three different structural types of chironomid community for different environmental properties, described by means of 7 significant abiotic factors (a multi-stressor gradient). Indicator species analysis revealed that the chironomid taxa most responsible for structural changes significantly varied in their abundance and frequency along the established environmental gradients. Out of 40 biological metrics based on the chironomid community, the multilayer perceptron (MLP), an supervised type of artificial neural network, derived 5 models in which the abundance of ...

Chironomidae - WikipediaChironomidae - Wikipedia
Larval stages of the Chironomidae can be found in almost any aquatic or semiaquatic habitat, including treeholes, bromeliads, rotting vegetation, soil, and in sewage and artificial containers. They form an important fraction of the macro zoobenthos of most freshwater ecosystems. They are often associated with degraded or low-biodiversity ecosystems because some species have adapted to virtually anoxic conditions and are dominant in polluted waters. Larvae of some species are bright red in color due to a hemoglobin analog; these are often known as bloodworms.[9] Their ability to capture oxygen is further increased by their making undulating movements.[10] Many reference sources in the past century or so have repeated the assertion that the Chironomidae do not feed as adults, but an increasing body of evidence contradicts this view. Adults of many species do, in fact, feed. The natural foods reported include fresh fly droppings, nectar, pollen, honeydew, and various sugar-rich materials.[1] The ...

Data about the karyotype characteristics, features of chromosomal polymorphism and larval morphology of populations of Chironomus bernensis Wülker & Klötzli, 1973 (Diptera, Chironomidae) from the Central Caucasus (the northern macroslope) and Ciscaucasia are presented. The characteristics of the pericentromeric regions of the long chromosomes of this species from Caucasian populations were very similar to the ones from some European populations (from Poland and Italy), but differed from Swiss and Siberian populations. In the North Caucasian populations 10 banding sequences were found: two in arms A, C, and E, and one in arms B, D, F, and G. Nine of them were already known for this species, and one, berC2, is described for the first time.

We compared feeding rates of the well-established, non-invasive amphipod Gammarus roeselii with those of the invasive Dikerogammarus villosus at different prey densities and different temperatures in laboratory experiments using chironomid larvae as prey. Feeding rates were very variable in both species but higher in the invader species than in the well-established non-invasive species. These results were age independent. At high temperature (18-20 °C) and high prey density (≥1000 prey m-2) one large adult D. villosus consumed 6-9 prey day-1 on average while one G. roeselii consumed 4-7 prey d-1 and one smaller D. villosus of a length of 8-10 mm consumed 2-5 prey d-1 while one G. roeselii of the same length consumed 3 prey d-1. Predation rate decreased considerably from high (18-20 °C) to low temperature (3±2 °C), from 9 to 4 prey predator-1 d-1 in D. villosus and from 7.5 to 2.5 prey predator-1 d-1 in G. roeselii.

Reflected polarization guides chironomid females to oviposition sites | Journal of Experimental BiologyReflected polarization guides chironomid females to oviposition sites | Journal of Experimental Biology
Chironomids (Diptera: Chironomidae; non-biting midges) are distributed worldwide, occupying a range of freshwater habitats such as streams, lakes and ponds. Mating occurs in the air during twilight (Armitage et al., 1995). After mating, the male dies, and the female descends to oviposit on the water surface. The eggs are laid in the form of egg batches (EB), each containing thousands of eggs wrapped in a gelatinous layer. Since the adults do not feed and are short lived, most females lay only once or twice and die soon after. Females usually oviposit in two stages, at the start of the evening and around sunrise. After emerging from the egg, the larva descends to the bottom of the water, where it feeds on the substrate and on suspended matter in the water. Then, 2-3 weeks later, the larva pupates and once the metamorphosis is complete, the pupa swims to the water surface, where the adult emerges into the air and is ready to mate (Pinder, 1986). Mating takes place within a couple of ...

Non-biting midges are one of the most diverse and widespread dipteran groups known. They inhabit virtually the entire range of aquatic ecosystems, both fresh and marine, as well as semi-terrestrial and terrestrial habitats. Most species have aquatic wormlike larval stages that start as egg masses laid on the water surface. After going through a pupal stage, floating at the surface of the water, a full-grown midge emerges and flies away. Larvae of some species build a protective capsule made of secretions and debris that they live in during the stage, emerging only long enough to feed.

Karyotypes of Chironomus Meigen (Diptera: Chironomidae) species from AfricaKaryotypes of Chironomus Meigen (Diptera: Chironomidae) species from Africa
The karyotypes of six African Chironomus species (Ch. alluaudi Kieffer, 1913, Ch. transvaalensis Kieffer, 1923, Ch. sp. Nakuru, Ch. formosipennis Kieffer, 1908, Ch. prope pulcher Wiedemann, 1830, Ch. sp. Kisumu) were investigated; four of these karyotypes were described for the first time (Ch. sp. Nakuru, Ch. formosipennis, Ch. prope pulcher, Ch. sp. Kisumu). Of the six Chironomus karyotypes, three had “pseudothummi” cytocomplex chromosome arms combinations AE CD BF G (Ch. alluaudi, Ch. transvaalensis, Ch. sp.

Diptera
The ZSM Diptera collection contains around 12,500 determined species (see lists of families, species, types), representing about 10% of the worlds scientifically described fly fauna. About 1,250 species are represented by type material. Additionally, there are large amounts of material still awaiting conclusive analysis. In the dry collection the core families are Asilidae, Bombyliidae, Conopidae, Diopsidae, Dolichopodidae, Leptogastridae, Limoniidae, Mycetophilidae, Pantophthalmidae, Stratiomyidae, Syrphidae, Tabanidae, Tachinidae, Tephritidae, and Tipulidae. The ZSMs special collection of Chironomidae (non-biting midges) includes about 60 000 microscope slides, making it one of the largest and most important of its kind. Another major part of the Diptera Section is the extensive alcohol collection, with the Chironomidae, Limoniidae and Mycetophilidae particularly well represented in terms of determined material. In addition, it contains much highly valuable yet incompletely studied material ...

A novel conserved RNA-binding domain protein, RBD-1, is essential for ribosome biogenesisA novel conserved RNA-binding domain protein, RBD-1, is essential for ribosome biogenesis
Synthesis of the ribosomal subunits from pre-rRNA requires a large number of trans-acting proteins and small nucleolar ribonucleoprotein particles to execute base modifications, RNA cleavages, and structural rearrangements. We have characterized a novel protein, RNA-binding domain-1 (RBD-1), that is involved in ribosome biogenesis. This protein contains six consensus RNA-binding domains and is conserved as to sequence, domain organization, and cellular location from yeast to human. RBD-1 is essential in Caenorhabditis elegans. In the dipteran Chironomus tentans, RBD-1 (Ct-RBD-1) binds pre-rRNA in vitro and anti-Ct-RBD-1 antibodies repress pre-rRNA processing in vivo. Ct-RBD-1 is mainly located in the nucleolus in an RNA polymerase I transcription-dependent manner, but it is also present in discrete foci in the interchromatin and in the cytoplasm. In cytoplasmic extracts, 20-30% of Ct-RBD-1 is associated with ribosomes and, preferentially, with the 40S ribosomal subunit. Our data suggest that ...

Biogenesis of messenger and ribosomal RNPs in the eukaryotic cellBiogenesis of messenger and ribosomal RNPs in the eukaryotic cell
In eukaryotic cells, gene expression involves multi-step processes in the nucleus and the cytoplasm. The different processes engage specific RNA-protein complexes, RNPs. Upon activation of most, if not all genes, a precursor RNA molecule is synthesized that has to be extensively processed and modified. In addition, the RNA has to associate with a distinct set of proteins. The composition of the RNP is often dynamic and changes over time. Several RNPs are exported to the cytoplasm, where they are involved in late steps of gene expression, including the synthesis of proteins.. The aim of this thesis has been to increase our knowledge about specific steps in messenger RNP (mRNP) and ribosomal RNP (rRNP) biogenesis in the eukaryotic cell.. We have characterized a novel protein, RBD-1, that is essential for ribosome biogenesis. RBD-1 contains six RNA-binding domains and is conserved in eukaryotes. In the dipteran Chironomus tentans, RBD-1 (Ct-RBD-1) is mainly located in the nucleolus, in an RNA ...

Species-specific PCR primers for identification of the sibling species Chironomus plumosus (Linnaeus, 1758) and Chironomus...Species-specific PCR primers for identification of the sibling species Chironomus plumosus (Linnaeus, 1758) and Chironomus...
Applicability of the polymerase chain reaction (PCR) with species-specific primers to obtaining molecular markers for identification of the sibling species of Chironomus plumosus group - C. plumosus and C. balatonicus - has been estimated. The nucleotide sequences of internal transcribed spacer (ITS) from the locus encoding ribosomal RNA (rRNA) were used as the source for designing the species-specific primers. The primers allowing for identification of C. plumosus and C. balatonicus were constructed. One primer pair (plu107F/plu363R) gives the PCR product MAR2, specific of C. plumosus, and the other (bal86F/plu363R), the PCR product MAR6, specific of C. balatonicus. The testing involving 18 species of the genus Chironomus confirmed the specificity of the primers. The results suggest that the PCR with species-specific primers is promising for construction of molecular markers for identification not only of these two, but also of other Chironomus species.. doi: 10.5324/fn.v31i0.1381..

Torbjørn Ekrem - NTNU
I am interested in evolution, systematics and biogeography, in particular of non-biting midges of the family Chironomidae (Diptera). My research focuses on taxonomy, biology, phylogeny, zoogeography and molecular systematics of genera and species in the tribe Tanytarsini, but I am also involved in work with other groups of animals and plants. Among these, tardigrades through the project Tardigrades in Norwegian forests.. The last few years I have been heavily involved in various priojects testing and using DNA barcoding in biosystematics. I am currently chairing the Norwegian Barcode of Life network and project (NorBOL) which is a national research infrastructure on DNA Barcoding. NorBOL aims to develop a barcode reference database for Norwegian species to support barcoding in applied projects (such as EBAI). I am also involved in the COST action DNAqua-Net as member of the Management Committee and co-lead of the working group on reference libraries.. ...

Benthic invertebrates affect microbial processes and communities in freshwater sediment by enhancing sediment-water solute fluxes and by grazing on bacteria. Using microcosms, the effects of larvae of thewidespread midge Chironomus plumosus on the efflux of denitrification products (N2O and N2+ N2O) and the diversity and abundance of nitrate- and nitrous-oxide-reducing bacteria were investigated. Additionally, the diversity of actively nitrate- and nitrous-oxide-reducing bacteria was analyzed in the larval gut.The presence of larvae increased the total effluxes of N2O and N2+N2O up to 8.6- and 4.2-fold, respectively, which was mostly due to stimulation of sedimentary denitrification; incomplete denitrification in the guts accounted for up to 20% of the N2O efflux. Phylotype richness of the nitrate reductase gene narG was significantly higher in sediment with than without larvae. In the gut, 47 narG phylotypes were found expressed, which may contribute to higher phylotype richness in colonized ...

Heavy metals and organophosphorus insecticide is known to act as disruptors for the enzyme system, leading to physiologic disorders. The present study was conducted to investigate the potential use of these enzymes as biomarkers in assessment of contaminated sediments on tropical chironomid species. Acetylcholinesterase (AChE), glutathione-S-transferase (GST) and metallothionein (MT) activity was measured in the fourth-instar chironomid larvae, Chironomus javanus, Kieffer, after either 48-hr or 96-hr exposure to organophosphorus insecticide, chlorpyrifos (0.01- 0.25 mg kg-1) or heavy metal cadmium (0.1-25 mg kg-1). Exposure to chlorpyrifos (0.01 mg kg-1) at 48 and 96 hr significantly of AChE activity (64.2 % -85.9%) and induced GST activity (33.9 - 63.8 %) when compared with control (P,0.05). Moreover, exposure to cadmium (0.1mg kg-1) at 48 and 96 hr also showed significant increas GST activity (11.7 - 40 %) and MT level (9.0 % - 70.5 %) when compared with control (P,0.05).
