A group of three related eukaryotic phyla whose members possess an alveolar membrane system, consisting of flattened membrane-bound sacs lying beneath the outer cell membrane.
Flagellate EUKARYOTES, found mainly in the oceans. They are characterized by the presence of transverse and longitudinal flagella which propel the organisms in a rotating manner through the water. Dinoflagellida were formerly members of the class Phytomastigophorea under the old five kingdom paradigm.
One of the three domains of life (the others being BACTERIA and ARCHAEA), also called Eukarya. These are organisms whose cells are enclosed in membranes and possess a nucleus. They comprise almost all multicellular and many unicellular organisms, and are traditionally divided into groups (sometimes called kingdoms) including ANIMALS; PLANTS; FUNGI; and various algae and other taxa that were previously part of the old kingdom Protista.
The relationships of groups of organisms as reflected by their genetic makeup.

Telomeres and telomerase activity in scleractinian corals and Symbiodinium spp. (5/52)

Telomeres are the repetitive sequences of DNA and associated proteins that cap the ends of eukaryotic chromosomes and play an essential role in maintaining chromosome stability. Compromised telomeres can lead to cell cycle arrest, senescence, apoptosis, or genetic instability, whereas maintenance of telomeres can endow cells with the capacity for indefinite self-renewal. Telomere integrity is maintained in most cells by the activity of telomerase, a ribonucleoprotein that can catalyze the addition of repeat sequences onto chromosome ends. Using the telomeric repeat amplification protocol (TRAP) assay, we detected telomerase activity in host nuclear extracts prepared from two scleractinian corals, Madracis auretenra and Madracis decactis, and also in cultured Symbiodinium, the symbiotic algae that live within corals. Sequencing the TRAP reaction products indicated that the telomeric DNA repeat sequence was TTAGGG for coral and TTTAGGG for Symbiodinium. Using this sequence information, we estimated telomere lengths by terminal restriction fragment (TRF) analysis to be greater than 19 kb for several species of coral and their associated Symbiodinium. Maintenance of coral telomeres by telomerase activity may be a mechanism that confers continuous growth and reproductive plasticity to these long-lived organisms.  (+info)

Apicomplexa are protist parasites that include Plasmodium spp., the causative agents of malaria, and Toxoplasma gondii, responsible for toxoplasmosis. Most Apicomplexa possess a relict plastid, the apicoplast, which was acquired by secondary endosymbiosis of a red alga. Despite being nonphotosynthetic, the apicoplast is otherwise metabolically similar to algal and plant plastids and is essential for parasite survival. Previous studies of Toxoplasma gondii identified membrane lipids with some structural features of plastid galactolipids, the major plastid lipid class. However, direct evidence for the plant-like enzymes responsible for galactolipid synthesis in Apicomplexan parasites has not been obtained. Chromera velia is an Apicomplexan relative recently discovered in Australian corals. C. velia retains a photosynthetic plastid, providing a unique model to study the evolution of the apicoplast. Here, we report the unambiguous presence of plant-like monogalactosyldiacylglycerol and
Chromera velia is an autotrophic protist isolated from stony corals. C. velia possesses a chloroplast thought to be most closely related to the apicoplasts of non-photosynthetic apicomplexa. . The ventral side of the flagellated C. velia cell has two grooves extending from the anterior flagella insertion point with a ridge rising towards the anterior apex of the cell. The anterior flagellum is shorter than the posterior flagellum and possesses a distinct, small curved appendage. The insertion point of the anterior flagellum is partly enclosed by a flap extending from the cell. The posterior flagellum is approximately four times the length of the cell and possesses mastigonemes. ...
Empirical evidence to assess the likely recovery rate of Sabellaria alveolata reefs from impacts is limited and significant information gaps regarding recovery rates, stability and persistence of Sabellaria alveolata reefs were identified for the biotope LS.LBR.Sab.Salv. No evidence was found regarding recovery of subtidal Sabellaria reefs on sediment and the resilience assessments are based on evidence for intertidal or shallow subtidal reefs on rock. Although the recovery mechanisms and life-history information should be applicable, the more limited extent of subtidal biotopes may restrict larval supply and the biotope will be more affected by sediment and water column conditions.. Studies carried out on reefs of Sabellaria alveolata within the low inter-tidal suggest that areas of small, surficial damage within reefs may be rapidly repaired by the tube building activities of adult worms. Vorberg (2000) found that trawl impressions made by a light trawl in Sabellaria alveolata reefs ...
We focus on the key results from a 3-year intensive investigation of soil protozoan diversity sponsored by the Natural Environment Research Council (UK). The investigation enabled us to study simultaneously all major protozoan groups at a single site-the 1 ha area of upland grassland at the Macaulay Land Use Research Institutes Sourhope Research Station in Southern Scotland. A total of 365 protozoan species were recorded, in four broad taxonomic groups-ciliates, testate amoebae, naked amoebae and flagellates. We explored the natural history of these groups, recording species richness, growth rates, and absolute abundance, as well as community structures within the context of the fractal character of the soil. We developed methods for estimating the abundance and growth potential of the soil protozoan community, plus seasonal variation in protozoan abundance within taxonomic groups. We isolated new species, re-described others, and produced a guide to the identification of testate amoebae in ...

Coral reefs, and their associated diverse ecosystems, are of enormous ecological importance. In recent years, coral health has been severely impacted by environmental stressors brought on by human activity and climate change, threatening the extinction of several major reef ecosystems. Reef damage is mediated by a process called coral bleaching where corals, sea anemones, and other cnidarians lose their photosynthetic algal symbionts (family Symbiodiniaceae) upon stress induction, resulting in drastically decreased host energy harvest and, ultimately, coral death. The mechanism by which this critical cnidarian-algal symbiosis is lost remains poorly understood. The larvae of the sea anemone, Exaiptasia pallida (commonly referred to as Aiptasia) are an attractive model organism to study this process, but they are large (∼100 mm in length, ∼75 mm in diameter), deformable, and highly motile, complicating long-term imaging and limiting study of this critical endosymbiotic relationship in live

The phylogenetic relationships of the Dinophyceae (Alveolata) are not sufficiently resolved at present. The Thoracosphaeraceae (Peridiniales) are the only group of the Alveolata that include members with calcareous coccoid stages; this trait is considered apomorphic. Although the coccoid stage appar- ently is not calcareous, Bysmatrum has been assigned to the Thoracosphaeraceae based on thecal morphology. We tested the monophyly of the Thoracosphaeraceae using large sets of ribosomal RNA sequence data of the Alveolata including the Dinophyceae. Phylogenetic analyses were performed using Maximum Likelihood and Bayesian approaches. The Thoracosphaeraceae were monophyletic, but included also a number of non-calcareous dinophytes (such as Pentapharsodinium and Pfiesteria) and even parasites (such as Duboscquodinium and Tintinnophagus). Bysmatrum had an isolated and uncertain phylogenetic position outside the Thoracosphaeraceae. The phylogenetic relationships among calcareous dinophytes appear ...

Size refers to individual worms. It is typically gregarious forming colonies of sheets, hummocks or reefs. In Cornwall, their tubes are up to 20 cm in length and around 5 mm in diameter at the external opening. Each tube has an additional porch over the opening. In northern France, the tubes were reported to grow in length at 12 cm/year.. This species appears to be favoured by elevated winter temperatures associated with cooling water discharges (Bamber & Irving, 1997) but growth is inhibited below 5 C. Communities associated with Sabellaria alveolata are not particularly remarkable being species poor on young dense reef and up to 38 species on older reefs. Honeycomb worm aggregations that bind together mobile cobbles increase heterogeneity. ...

Perkinsus atlanticus cultures were established either with trophozoites isolated from fresh gills, with hypnospores isolated from tissues incubated in fluid thioglycollate medium, or directly from infected hemocytes of carpet shell clams Tapes decussatus from Algarve (Southern Portugal), using a culture medium and conditions optimized for Perkinsus marinus. Perkinsus atlanticus isolates were cloned by limiting dilution, and their identity unequivocally established by PCR-based species-specific diagnostic assays, and by sequencing the complete rRNA gene cluster. The rRNA gene cluster is 7.5-kb in length including 5S, IGS, SSU, ITS1, 5.8S, ITS2, LSU, and an inter-cluster spacer. rDNA sequences of the P. atlanticus clone were between 98.3-100% identical to P. atlanticus sequences previously obtained from clam tissue (non-clonal) isolates. Based on the IGS sequences available from Perkinsus species, a set of primers was designed to amplify P. atlanticus and the two clonally cultured Perkinsus ...

The number of cingular plates has been used to differentiate Protoperidinium from Peridinium and related genera. Protoperidinium is characterized by the presence of three cingular plates plus a transitional plate (3C+t). However, many Protoperidinium species have been described that exhibit different cingular plate tabulations. How these species should be classified within the genus remains unclear. To address this question, the phylogenetic relationship of four Protoperidinium species, with three or four cingular plates and lacking a transitional plate, were examined in relationship to other Protoperidinium species. These four species were germinated from cysts deposited in surface sediments collected from the East China Sea, the Bohai Sea and the Yellow Sea. Three of the isolated species, P. tricingulatum, P. americanum and P. parthenopes, were described previously. The fourth is here described as P. haizhouense sp. nov. with the plate formula Po, X, 4′, 3a, 7′′, 3C, 6S, 5′′′, ...

Many cnidarians, including the reef-building corals, undergo symbiotic mutualisms with photosynthetic dinoflagellate algae of the family Symbiodiniaceae. These partnerships are sensitive to temperature extremes, which cause symbiont loss and increased coral mortality. Previous studies have implicated host immunity and specifically immunity transcription factor NF-κB as having a role in the maintenance of the cnidarian-algal symbiosis. Here we have further investigated a possible role for NF-κB in establishment and loss of symbiosis in various strains of the anemone Exaiptasia (Aiptasia) and in the coral Pocillopora damicornis. Our results show that NF-κB expression is reduced in Aiptasia larvae and adults that host certain algae strains. Treatment of Aiptasia larvae with a known symbiosis-promoting cytokine, transforming growth factor β, also led to decreased NF-κB expression. We also show that aposymbiotic Aiptasia (with high NF-κB expression) have increased survival following infection ...
Rapid and specific detection of extended-spectrum β-lactamase-producing (ESBL) bacteria is crucial both for timely antibiotic therapy when treating infected patients as well as for appropriate infection control measures aimed at curbing the spread of ESBL-producing isolates. Whereas a variety of phenotypic methods are currently available for ESBL detection, they remain time consuming and sometimes difficult to interpret while being also affected by a lack of sensitivity and specificity. Considering the longer turnaround time (TAT) of susceptibility testing and culture results, DNA-based ESBL identification would be a valuable surrogate for phenotypic-based methods. Putative ESBL-positive Enterobacteriaceae isolates (n = 330) from clinical specimen were prospectively collected in Bulgaria, Romania and Democratic Republic of Congo and tested in this study. All isolates were assessed for ESBL-production by the E-test method and those giving undetermined ESBL status were re-tested using the ...
Actin Dynamics: Roles in Cell and Tissue Morphogenesis in Development. Our laboratory studies the role of actin dynamics in regulating assembly and function of the diverse cytoskeletal structures that contribute to cell and tissue morphogenesis during embryonic development. Current research focuses on tropomodulins (Tmods), a conserved family of actin pointed end-capping proteins that block association and dissociation at slow-growing (pointed) ends of actin filaments. Tmods also bind tropomyosins (TMs), which cooperate with Tmods to tightly cap actin pointed ends, regulating actin filament lengths and stability in the spectrin-based membrane skeleton of non-muscle cells and in the contractile myofibrils of skeletal and cardiac muscle. Differences among Tmod family members in expression patterns, TM isoform binding, and actin monomer and polymer regulation suggest unique functions for each of the four vertebrate Tmods. Recent studies of mouse knockouts further implicate key requirements for ...
It is important for people with foot pain to know if they have flat feet. The following tests can help you determine your arch type. When you get out of a swimming pool, look at your footprint on the concrete. The front of the foot will be joined to the heel by a strip. If your foot is flat, then the strip is the same width as the front of the foot, creating a footprint that looks like a stretched out pancake. With a normal arch, the strip is about half the width of the front of the foot. If you have a high arch, only a thin strip connects the front of the foot with the heel. Put your shoes on a flat table and view them at eye level from behind. See if the sole is worn evenly. A flat foot will cause more wear on the inside of the sole, especially in the heel area. The shoe will easily rock side to side. A flat foot will also cause the upper part of the shoe to lean inward over the sole. Both shoes should wear about the same way. If you have pain in one foot, you should make sure you dont have a ...
Determining the photosynthetic relatives of Rafflesiales has long presented a challenge owing to the extreme reduction and/or modification of morphological structures that have accompanied the evolution of this lineage [3, 11]. Molecular phylogenetic approaches, although providing great promise in resolving such questions, also come with their own set of challenges that includes losses of some genes, substitution rate increases in other genes, and horizontal gene transfer. Examples of the first process can be seen in chloroplast genes such as rbcL that are typically used to infer phylogenetic relationships among angiosperms but have not yet been amplified from any Rafflesiales and are presumed lost [5]. Increased substitution rates in the normally conservative plastid rDNA has been demonstrated in these holoparasites [4, 12]. Similarly, accelerated rates in mitochondrial SSU rDNA, typically very conservative in many photosynthetic angiosperms, occur in Rafflesia and Cytinus [13]. Despite these ...

Symbioses between microbes and higher organisms underpin high diversity in many ecosystems, including coral reefs, however mechanisms underlying the early establishment of symbioses remain unclear. Here we examine the roles of Symbiodinium type and cell surface recognition in the establishment of algal endosymbiosis in the reef-building coral, Acropora tenuis. We found 20-70% higher infection success (proportion of larvae infected) and five-fold higher Symbiodinium abundance in larvae exposed to ITS-1 type C1 compared to ITS-1 type D in the first 96 h following exposure. The highest abundance of Symbiodinium within larvae occurred when C1-type cells were treated with enzymes that modified the 40-100 kD glycome, including glycoproteins and long chain starch residues. Our finding of declining densities of Symbiodinium C1 through time in the presence of intact cell surface molecules supports a role for cell surface recognition molecules in controlling post-phagocytosis processes, leading to ...

A Perspective on Biogenic Reefs and SACs The distribution of major examples of biogenic reefs is given by species in Table 3 and Figure 2, both within cSACs and pSACs, and elsewhere. No currently proposed SACs were selected specifically on the basis that they contain biogenic reefs. However, biogenic reefs are sub-features of other Annex I features such as reefs , estuaries or large shallow inlets and bays . In some cases biogenic reefs are specifically mentioned as reasons why a site is a particularly good example of an Annex 1 habitat e.g. Mytilus in Morecambe Bay, Modiolus in Strangford Lough, Lleyn Peninsula and the Sarnau and Loch Maddy; Sabellaria alveolata in the Solway Firth and Morecambe Bay. There are candidate SACs selected on the basis of the presence of reefs which do have substantial areas of Modiolus reef (Lochs Duich, Long and Alsh, Lleyn Peninsula and the Sarnau), Sabellaria alveolata reef (Lleyn Peninsula and the Sarnau); and probably Sabellaria spinulosa reef (Lleyn Peninsula ...

Coined:The first attempt for describing and naming organisms is began by ancient philosopher Aristotle (384-322BC) who tried to classify animal species in his work : The History of Animals. In parallel his pupill Theophrastus (c.371-c.287 BC) wrote about plant classification (Historia Plantarum). During the 1700s Swedish botanist, physician and zoologist Carl Linnaeus (1707 -1778) simplified the classification system of living organisms by imparting a two-part naming system, called binomial nomenclature, to make identification easier. American plant ecologist Robert Harding Whittaker (1920-1980) in 1969 proposed 5 kingdoms: Plantae, Animalia, Fungi, Protista and Monera. Prof Thomas Cavalier-Smith (1942- ) proposed a new Kingdom of Chromista in the system of 6 kingdoms: Plantae (eukaryotic characterised by cell wall) , Animalia (eukaryotic characterised by cells without cell wall), Fungi (eukaryotic characterised by cells without cell wall), Chromista (eukaryotic algae), Protozoa (unicellular ...

Ang protista (Ingles: protist IPA: /ˈproʊtɨst/), ay pangkat ng magkakaibang mga eukaryotikong mikroorganismo. Sa kasaysayan, tinuturing ang mga protista bilang kasapi ng kahariang Protista subalit hindi na ito kinikilala sa makabagong taksonomiya.[1] Walang masyadong pagkakatulad ang mga protista maliban sa isang medyo payak na organisasyon - na maaaring sanselula sila o multiselula sila na walang natatanging mga tisyu. Naiiba ang payak na pagkakaayos ng selular sa ibang eukaryote, katulad ng mga halamang singaw, hayop at halaman. Unang ginamit ang katawagang protista ni Ernst Haeckel noong 1866. Tradisyunal na nahahati ang mga protista sa ilang mga pangkat na nakabatay sa pagkakatulad ng "mas mataas" na mga kaharian: ang isahang-sihay na mala-hayop na protosowa, ang mala-halaman na protopayta (karamihang isahang-sihay na lumot), at mala-halamang-singaw na mga myxomycota. Dahil kadalasang nagsasanib ang mga pangkat nito, pinalitan sila ng pilohenetikang batayan sa pag-uuri. Bagaman, magagamit ...

Life cycle : The life cycle observed in culture for this Pinguicula consists of two seasons, one wet and the other dry (see link). The plant forms different leaf rosettes according to the season. During the resting months (winter) the small succulent rosette is composed of numerous non-carnivorous leaves. The carnivorous leaves are produced in spring and during all summer. The life cycle of the plant is probably similar in its native habitat but I have no data.. Media : I use a 100 % mineral media : 2 perlite, 2 vermiculite, 1 small sand (for aquarium), 1 fine white sand, 1 pouzzolane (volcanic lava), 1 aqualit (expansed ceramic for aquarium). The aqualit can be replaced by 1 of pouzzolane. Plants in this media grow slower but have a stronger root system.. Pot : plastic, colour terracotta, diameter 12.5cm, height 12cm.. Cultivation : I think that a slightly airy situation inside the greenhouse is important to avoid air stagnation. For this reason, I use a fan 24h/24h all the year ...
