Abstract. We estimated the phylogeny of order Odonata, based on sequences nuclear ribosomal genes 5.8 S, 18S, and ITS1 2. An 18S‐only analysis resolved deep relationships well: as well suborders Zygoptera Epiprocta (Anisoptera + Epiophlebia ), emerged monophyletic. Some other clades well, but support for more recently diverged was generally weak. A second, simultaneous, 5.8S 18S with intergenic spacers 2 some recent branches better, appeared less reliable with, example, suborder Anisoptera...
Pinpointing processes that structure the geographical distribution of genetic diversity marine species and lead to speciation is challenging because lack obvious dispersal barriers likelihood substantial (passive) in oceans. In addition, cryptic radiations with sympatric distributions abound species, allopatric mechanism. Here, we present a phylogeographical study nematode complex Rhabditis (Pellioditis) marina investigate shaping speciation. (P.) lives on decaying macroalgae intertidal, may...
Correct taxonomy is a prerequisite for biological research, but currently it undergoing serious crisis, resulting in the neglect of many highly diverse groups organisms. In nematodes, species delimitation remains problematic due to their high morphological plasticity. Evolutionary approaches using DNA sequences can potentially overcome problems caused by morphology, they are also affected theoretical flaws. A holistic approach with combination and molecular methods therefore produce...
Oxford Nanopore Technologies (ONT) is a third-generation sequencing technology that gaining popularity in ecological research for its portable and low-cost possibilities. Although the excels at long-read sequencing, it can also be applied to sequence amplicons. The downside of ONT low quality raw reads. Hence, generating high-quality consensus still challenge. We present Amplicon_sorter, tool reference-free sorting sequenced amplicons based on their similarity length building solid sequences.
The diversity of eukaryote organisms and viruses associated with wild bees remains poorly characterized in contrast to the well-documented pathosphere western honey bee, Apis mellifera. Using a deliberate RNA shotgun metagenomic sequencing strategy combination dedicated bioinformatics workflow, we identified (micro-)organisms two bumble bee hosts, Bombus terrestris pascuorum, solitary Osmia cornuta Andrena vaga. Ion Torrent semiconductor generated approximately 3.8 million high quality...
Most aging hypotheses assume the accumulation of damage, resulting in gradual physiological decline and, ultimately, death. Avoiding protein damage by enhanced turnover should slow down process and extend lifespan. However, lowering translational efficiency extends rather than shortens lifespan C. elegans. We studied individual proteins long-lived daf-2 mutant combining SILeNCe (stable isotope labeling nitrogen Caenorhabditis elegans) mass spectrometry. Intriguingly, majority displayed...
Aim To reconstruct the phylogeographic history of Holarctic carnivorous genus Leptodora (Crustacea: Cladocera: Haplopoda). Location We studied DNA between one and five specimens each from 28 populations distributed across Holarctic, but with emphasis on Eurasia. Methods sequenced a mitochondrial (cytochrome c oxidase subunit I) nuclear (elongation factor-1α) gene, combined this molecular information geological palaeoclimatological data. Haplotype networks phylogenetic trees were constructed...
The emergence of high throughput genome sequencing facilities and powerful performance bioinformatic tools has highlighted hitherto unexpected wide occurrence globins in the three kingdoms life. In silico analysis C. elegans identified 33 putative globin genes. It remains a mystery why this tiny animal might need so many globins. As an inroad to understanding complexity we initiated structural functional family elegans.All genes are transcribed. translated sequences have essential signatures...
Abstract Aim The brackish water mysid, Neomysis integer , is one of the most common mysid species along coasts north‐east Atlantic. In present study, phylogeographical patterns were examined throughout distribution range N. . particular, latitudinal trends in genetic diversity and variation order to elucidate imprints Pleistocene glaciations. Location North‐east Atlantic from Baltic Sea south Spain. Methods A total 461 specimens 11 populations analysed by means single‐stranded conformation...
Background All globins belong to one of three families: the F (flavohemoglobin) and S (sensor) families that exhibit canonical 3/3 α-helical fold, T (truncated fold) characterized by a shortened 2/2 fold. eukaryote hemoglobins are related bacterial single domain globins. It is known Fungi contain flavohemoglobins Our aims provide census fungal examine their relationships Results Examination 165 genomes revealed present in >90% Ascomycota ∼60% Basidiomycota genomes. The occur...
Aeshnidae Rambur, 1842 are impressive large insects distributed worldwide. Currently, over 500 species recognized. Nevertheless, the phylogeny of this family is not completely understood. We applied molecular phylogenetic analysis using two popular markers, mitochondrial COI gene fragment (barcoding sequence) and nucleic ITS region, containing ITS1, 5.8S rRNA, ITS2 sequences. used available credible published sequences 96 newly sequenced specimens. Our involved all West Palaearctic species,...
Taxonomy of the genus Cordulegaster Leach in Brewster, 1815 Eastern part Western Palaearctic is poorly resolved. A two-step approach was applied: sequences mitochondrial and nuclear DNA fragments were used to sort specimens; known or new taxa with their phenotypic variation described. The existence two traditional groups (boltonii- bidentata-group) confirmed. coronata Morton, 1916, however, belongs a different group. Molecular-analysis supported three one species (C. heros Theischinger,...
Abstract The aim of our study was to annotate sequences for 35 putative globins from the nematode Caenorhabditis elegans. All these proteins are expressed, but seven differ gene predictions in Wormbase. entire polypeptide 31 genes and core globin domain four were confirmed or corrected. domains aligned manually following a procedure that designed fit crystal structure based alignment 56 known structures. Neighbor‐joining analysis resulting showed majority very divergent each other, possibly...
The placement and relationships of the red-and-black zygopteran Pyrrhosoma, currently considered to be part Teinobasinae, has long been uncertain.DNA fragments (COI ITS) reveal that Pyrrhosoma s.s. is restricted West Palaearctic, with two morphologically distinct name-bearing clades (nymphula, elisabethae), a indistinct third clade in Middle Atlas, Morocco, might close common ancestor all three.Chromagrion, closest relative found North America, not South Asia.Two isolated Chinese taxa...
