A group of protist experts proposes a two-step DNA barcoding approach, comprising universal eukaryotic pre-barcode followed by group-specific barcodes, to unveil the hidden biodiversity microbial eukaryotes.
Abstract Photosynthetic eukaryotes have a critical role as the main producers in most ecosystems of biosphere. The ongoing environmental metabarcoding revolution opens perspective for holistic biological studies these organisms, particular unicellular microalgae that often lack distinctive morphological characters and complex life cycles. To interpret sequences, necessarily relies on taxonomically curated databases containing reference sequences targeted gene (or barcode) from identified...
Background Dinoflagellates are an ecologically important group of protists with functions as primary producers, coral symbionts and in toxic red tides. Although widely studied, the natural diversity dinoflagellates is not well known. DNA barcoding has been utilized successfully for many protist groups. We used this approach to systematically sample known “species”, a reference measure three marine environments. Methodology/Principal Findings In study, we assembled large cytochrome c oxidase...
DNA barcoding offers an efficient way to determine species identification and measure biodiversity. For dinoflagellates, ancient alveolate group of about 2000 described extant species, studies have revealed large amounts unrecognized diversity, most which is not represented in culture collections. To date, two mitochondrial gene markers, Cytochrome Oxidase I (COI) b oxidase (COB), been used assess both failed amplify all taxa suffered from low resolution. Nevertheless, genes yielded many...
Infection of bovine leukocytes by the apicomplexan parasite Theileria annulata results in alteration host cell gene expression and stimulation proliferation. At present, parasite-derived factors involved these processes are unknown. Recently, we described characterisation a (TashAT2), whose polypeptide product bears AT hook DNA-binding motifs may be transported from to nucleus. We now describe isolation further two genes (TashAT1 TashAT3) that very closely related TashAT2. All three TashAT...
Abstract. Scientific debate on whether or not the recent increase in reports of jellyfish outbreaks represents a true rise their abundance has outlined lack reliable records Cnidaria and Ctenophora. Here we describe different data sets produced within EU programme EURO-BASIN. These were assembled with aim creating an improved baseline providing new that can be used to evaluate current diversity standing stocks North Atlantic region. Using net adapted sample gelatinous zooplankton...
Chlorarachniophytes are a small group of marine photosynthetic protists. They best known as examples an intermediate stage secondary endosymbiosis: their plastids derived from green algae and retain highly reduced nucleus, called nucleomorph, between the inner outer pairs membranes. can be challenging to identify species level, due size, complex life cycles, fact that even genus-level diagnostic morphological characters observable only by EM. Few have been formally described, many available...
The phylogeny of ligulate and sulfuric-acid containing species Desmarestia, occurring worldwide from polar to temperate regions, was revised using a multigenic polyphasic approach. Sequence data, gametophyte characteristics, sporophyte morphology support reducing total 16 taxa four different species. (1) D. herbacea, broad-bladed highly branched forms, has dioecious gametophytes. three other have monoecious gametophytes: (2) ligulata which is profusely and, except for one subspecies,...
Two monospecific genera of marine benthic dinoflagellates, Adenoides and Pseudadenoides, have unusual thecal tabulation patterns (lack cingular plates in the former; no precingular a complete posterior intercalary plate series latter) are thus difficult to place within phylogenetic framework. Although both share morphological similarities, they not formed sister taxa previous molecular analyses. We discovered characterized new species P. polypyrenoides sp. nov., at ultrastructural levels....
