Invertebrate nervous systems are highly disparate between different taxa. This is reflected in the terminology used to describe them, which very rich and often confusing. Even general terms such as 'brain', 'nerve', 'eye' have been various ways animal groups, but no consensus on exact meaning exists. impedes our understanding of architecture invertebrate system evolutionary transformations characters taxa.We provide a glossary neuroanatomical with precise consistent terminology,...
Despite a large and multifaceted effort to understand the vast landscape of phenotypic data, their current form inhibits productive data analysis. The lack community-wide, consensus-based, human- machine-interpretable language for describing phenotypes genomic environmental contexts is perhaps most pressing scientific bottleneck integration across many key fields in biology, including genomics, systems development, medicine, evolution, ecology, systematics. Here we survey phenomics...
Three-dimensional (3D) laser micro- and nanoprinting has become a versatile, reliable, commercially available technology for the preparation of complex 3D architectures diverse applications. However, vast majority structures published so far have been composed only single constituent material. Here, we present system based on microfluidic chamber integrated into state-of-the-art lithography apparatus. This is scalable in terms number materials eliminates need to go back forth between...
Although the biology of reptantian Decapoda has been much studied, last comprehensive review systematics was published more than 80 years ago. We have used cladistic methods to reconstruct phylogenetic system Decapoda. can show that Reptantia represent a monophyletic taxon. The classical groups, ‘Palinura’, ‘Astacura’ and ‘Anomura’ are paraphyletic assemblages. Polychelida is sister-group all other reptantians. Astacida not closely related Homarida, but part large taxon which also includes...
A highly specific stromal processing activity is thought to cleave a large diversity of precursors targeted the chloroplast, removing an N-terminal transit peptide. The identity this key component import machinery has not been unequivocally established. We have previously characterized chloroplast enzyme (CPE) that cleaves precursor light-harvesting chlorophyll a/b binding protein photosystem II (LHCPII). Here we report overexpression active CPE in Escherichia coli . Examination recombinant...
Understanding the evolution of Tetraconata or Pancrustacea-the clade that includes crustaceans and insects-requires a well-resolved hypothesis regarding relationships within among its constituent taxa. Here, we assembled taxon-rich phylogenomic dataset focusing on crustacean lineages based solely genomes new-generation Illumina-generated transcriptomes, including 89 representatives Tetraconata. This constitutes, to our knowledge, first study specifically addressing internal Malacostraca...
The phylogenetic relationships of branchiopod crustaceans have been in the focus a number recent morphological and molecular systematic studies. Although agreeing some respects, major differences remain. We analyzed sequences characters for 43 branchiopods two outgroups. terminals comprise all eight "orders". data include six loci: nuclear ribosomal genes (18S rRNA, 28S rRNA), mitochondrial (12S 16S one protein coding gene (elongation factor 1α), (cytochrome c oxidase subunit I). A total 65...
The current epidemic of infections caused by antibiotic-resistant Gram-positive bacteria requires the discovery new drug targets and development therapeutics. Lipoteichoic acid (LTA), a cell wall polymer bacteria, consists 1,3-polyglycerol-phosphate linked to glycolipid. LTA synthase (LtaS) polymerizes polyglycerol-phosphate from phosphatidylglycerol, reaction that is essential for growth bacteria. We screened small molecule libraries compounds inhibiting Staphylococcus aureus but not...
Throughout the history of biology since time Goethe, morphology as a discipline has been not only descriptive but explanatory too. Both, itself and its central concept, homology, are pre-Darwinian in origin, result dubious eyes many. Although taken evolution into account Darwin, contribution scientific to evolutionary is matter dispute. This paper can be regarded conceptualization research program for Evolutionary Morphology, term we use characterize field which includes description,...
We demonstrate that by formulating guidelines for evolutionary morphology the transparency, reproducibility, and intersubject testability of hypotheses based on morphological data can be enhanced. The five main steps in our concept are (i) taxon sampling, (ii) structural analysis, (iii) character conceptualization, (iv) phylogenetic (v) interpretation. illustrate this example circulatory organs peracarid Malacostraca. analysis is recently published accounts which detailed analyses were...
Advances in supramolecular chemistry are often underpinned by the development of fundamental building blocks and methods enabling their interconversion. In this work, we report use an underexplored dynamic covalent reaction for synthesis stimuli-responsive [2]rotaxanes. The formamidinium moiety lies at heart these mechanically interlocked architectures, because it enables both exchange binding simple crown ethers. We demonstrated that rotaxane self-assembly follows a unique pathway complex...
This study investigates whether managers' voluntary tax forecasts provide a unique signal of future firm performance and the market fully incorporates information into earnings expectations. We propose that release forecast serves as an implicit indicator management's optimism about performance. find firms voluntarily disclosing effective rate (ETR) during conference calls have higher profitability sales revenue in periods. In addition, this does not seem to be incorporated by participants,...
The main goal of this study has been to explore and compare the functional morphology photoadaptive patterns compound eyes two closely related prawn species both inhabiting different infralittoral visual environments. Using light transmission electron microscopy we investigated light- dark-adapted ommatidia light-resistant Palaemon elegans shade-preferring xiphias. Ommatidia generally share same cellular architecture, except for irregular 8th retinula cell building up distal rhabdom. This...
A stromal processing peptidase (SPP) cleaves a broad range of precursors targeted to the chloroplast, yielding proteins for numerous biosynthetic pathways in different compartments. SPP contains signature zinc-binding motif, His-X-X-Glu-His, that places it metallopeptidase family which includes mitochondrial peptidase. Here, we have investigated mechanism cleavage by SPP, late, yet key event import pathway. Recombinant removed transit peptide from variety single endoproteolytic step. Whereas...
The Brachyura, within the decapod crustaceans, is one of most species-rich taxa with up to 10 000 species. However, its phylogenetic history, evolution and fossil record remain subjects controversy. In our study, we examined relationships Brachyura based on morphological characters foregut. cladistic analysis supports a monophyletic including Dromiidae Raninidae. A clade comprising Dynomenidae forms basal assemblage followed by Homolidae Latreilliidae. As result, neither Podotremata nor...
Bacillus anthracis, the causative agent of anthrax, is a dangerous biological weapon, as spores derived from drug-resistant strains cause infections for which antibiotic therapy no longer effective. We sought to develop an anti-infective anthrax and targeted CapD, enzyme that cleaves poly-gamma-D-glutamate capsule generates amide bonds with peptidoglycan cross-bridges deposit capsular material into envelope B. anthracis. In agreement model confers protection phagocytic clearance, anthracis...
The unambiguous delineation and identification of species remain central problems in systematic taxonomic studies. Species depends on the data utilized concept applied. In recent years, morphology-based has been complemented by DNA sequence data, leading to an integrative taxonomy. Such approaches, however, are hampered partial incongruence various types with certain concepts. this study, we delineated Australian Limnadopsis employing one mitochondrial (cytochrome c oxidase subunit I, COI)...
Abstract 3D optical security features manufactured by multistep laser lithography are presented. These microstructures composed of a nonfluorescent cross‐grid scaffold and fluorescent markers, realized an acrylate‐based resist containing CdSSe‐based core–shell semiconductor quantum dots, arranged onto this at will. The readout these can be (exclusively) achieved sectioning methods, for example, confocal fluorescence scanning microscopy. As examples, structures with five different layers...
