The abyssal plains of the Clarion-Clipperton Zone (CCZ) are famous for their fields polymetallic nodules, which inhabited by benthic invertebrates. Ten specimens from Interoceanmetal Joint Organisation (IOM) licence area in CCZ were collected 2014 and submitted to a short-read genome skimming sequencing. In total, mitochondrial genomes nuclear ribosomal genes retrieved nine different organisms belonging Ophiuroidea, Holothuroidea, Polychaeta, Bryozoa, Porifera, Brachiopoda (assigned these...

Daniszewska-Kowalczyk, G.; Kierzek, A., and Hajrah, N. H., 2016. Multigene assessment of biodiversity diatom (Bacillariophyceae) assemblages from the littoral zone Bohai Yellow Seas in Yantai region Northeast China with some remarks on ubiquitous taxa. Diatoms are important contributors to benthic...
Dozens of monoclonal cultures small-celled araphid diatoms from brackish or marine habitats worldwide were analyzed using morphological observations (light and electron microscopy) molecular data (nuclear-encoded small subunit ribosomal RNA chloroplast encoded rbcL psbC). As a result, we established one new genus Gedaniella, distinguished by shared character (occlusions branched volae, projecting the apical sides areolae) some data, including five species: G. alfred-wegeneri, arenaria,...
Abstract A monophyletic group of dinoflagellates, called ‘dinotoms’, are known to possess evolutionarily intermediate plastids derived from diatoms. The diatoms maintain their nuclei, mitochondria, and the endoplasmic reticulum in addition with plastids, while it has been observed that host dinoflagellates retain permanently by controlling diatom karyokinesis. Previously, we showed dinotoms have repeatedly replaced Here, show process replacements is at two different evolutionary stages...
Plagiogrammaceae, a poorly described family of diatoms, are common inhabitants the shallow marine littoral zone, occurring either in sediments or as epiphytes. Previous molecular phylogenies Plagiogrammaceae were inferred but included only up to six genera: Plagiogramma, Dimeregramma, Neofragilaria, Talaroneis, Psammogramma and Psammoneis. In this paper, we describe new plagiogrammoid genus, Orizaformis, obtained from Bohai Sea (China) present based on three four genes (nuclear-encoded large...
:The focus of this paper is the sexual reproduction and phylogeny Schizostauron Grunow, which were studied using clonal cultures isolated from Indian Ocean coast Mozambique near Tofo Bazaruto. Taxa characterized by light electron microscopy a derived three genes (rbcL, psbC short subunit). was established in second half 19th century, then forgotten, with its taxa included Cocconeis or Achnanthes sensu lato. Schizostauron, together Astartiella perhaps also Kolbesia Karayevia, seems to form...
Abstract The genus Simonsenia is reviewed and S . aveniformis described as new for science by light electron microscopy. species originated from estuarine environments in southern Iberia (Atlantic coast) was isolated into culture. In LM, resembles Nitzschia , with bridges (fibulae) beneath the raphe, which marginal. It only microscope (EM) examination that reveals true structure of raphe system, consists a canal raised on keel (wing), supported rib like braces (fenestral bars) tube-like...
In many marine littoral and sublittoral benthic habitats, we find small diatoms with few features resolvable light microscopy (LM) other than internal costae across their valves. While classically those have defined identification classification, the use of electron molecular data started to reveal true diversity unrelated forms genera (e.g., Anaulus, Eunotogramma, Hustedtiella, or Plagiogramma) which possess these structures. Here describe new genus Ambo, in an attempt clarify some...
The family Cymatosiraceae, composed of two subfamilies (Cymatosiroideae and Extubocelluloideae), are elongate, non‐pennate diatoms commonly reported in marine planktonic benthic assemblages all over the world. combination gross bilateral symmetry frustule radial valve poration, distinct pore fields at apices DNA sequence data place this controversial diatom class Mediophyceae, sister to pennate diatoms. relationships Cymatosiraceae within monophyly cymatosiroid subfamilies, have become less...
In the present investigation, fucoxanthin—one of major pigments in diatoms—has been extracted from Nanofrustulum shiloi SZCZM1342, and its reducing efficiency biogenesis gold nanoparticles (GNPs) was checked. Fucoxanthin golden-brown cells N. compared to healthy, growing biomass standard fucoxanthin after separate exposure 25 mg L−1 aqueous hydrogen tetrachloroaurate solutions at room temperature.

Nanostructures-assisted laser desorption/ionization mass spectrometry (NALDI-MS) is gaining attention for the analysis of a wide range molecules. In this present investigation, Pseudostaurosira trainorii mediated biosynthesized iron-oxide nanoparticles (IONPs) have been utilized as nanostructures assisting ionization and desorption (LDI-MS). The chain forming diatom, P. showed efficiency in production IONPs against 0.01 M Fe+3 (pH 2) aqueous solution at intracellular extracellular level....
Diatoms represent, in terms of species number, one the largest groups microalgae that have ability to synthesize phenomenal mineral composites characterized by complex hierarchical structures. Their shells, called frustules, create intricately ornamented structures, reminiscent most sophisticated, natural mosaics. Ordinated pore systems perforate siliceous walls frustules with diameters ranging from nano micro-scale, forming openwork three-dimensional silica The use these features is main...
Lipid nanocarriers smaller than 200 nm may be used as pharmaceutical/cosmetic raw materials they are able to penetrate the skin. The nanostructured lipid carriers (NLCs) based on microalgae oil (Schizochytrium) and lipids extracted from diatoms (Halamphora cf. salinicola (strain SZCZM1454A)) were produced by HSH (high shear homogenization) method. Fatty acid profile of crude indicated presence palmitoleic, palmitic, stearic acid, oleic myristic acids most common fatty in strain investigated....
Dinoflagellates of the family Kryptoperidiniaceae, known as "dinotoms", possess diatom-derived endosymbionts and contain individuals at three successive evolutionary stages: a transiently maintained kleptoplastic stage; stage containing multiple permanently diatom endosymbionts; further permanent single endosymbiont. Kleptoplastic dinotoms were discovered only recently, in Durinskia capensis; until now it has not been investigated behavior metabolic genetic integration host prey. Here, we...
Presented here are new insights into the marine monoraphid diatom genera Schizostauron and Astartiella , based on molecular morphological data, including descriptions of species. Although no unambiguous synapomorphies between two currently recognized, they closely related by DNA sequence data.
