Chromerids are alveolate algae that are the closest known phototrophic relatives to apicomplexan parasites s … Red and problematic green phylogenetic signals among thousands of nuclear genes from the photosynthetic and apicomplexa-related Chromera velia C Woehle, T Dagan, WF Martin, SB Gould Genome biology and evolution 3, 1220-1230 , 2011

High light acclimation of Chromera velia points to photoprotective NPQ. Photosynthesis Research 2018, 135 (1-3) , 263-274. DOI: 10.1007/s11120-017-0385-8. Tjaart P. J. Kr chel, Rienk van Grondelle. Abstract. Chromera velia was discovered a decade ago associated with stony corals in the Great Barrier Reef and Sydney Harbour, Australia. This unicellular alveolate possesses housekeeping genes and ultrastructural features typical of apicomplexans, and has active photosynthetic pathways related to … The chromerids, Chromera velia and Vitrella brassicaformis, were included as outgroups. The closest known free-living relatives of apicomplexans, Chromera velia and Vitrella brassicaformis, have more sugar transporters than the apicomplexans at 28 and 24 sugar transporters, respectively (Figure 1). Most photosynthetic eukaryotes synthesize both heme and chlorophyll via a common tetrapyrrole biosynthetic pathway starting from glutamate. This pathway was derived mainly from cyanobacterial predecessor of the plastid and differs from the heme synthesis of the plastid-lacking eukaryotes. Here, we show that the coral-associated alveolate Chromera velia , the closest known photosynthetic Chromera velia gen. Et sp. Nov. Etymology. Chromera (feminine), derived from the English words chromophore and meront, because in pure culture the pigmented plastid was inherited through cell This novel alga, named Chromera velia, contains ultrastructural features typical for apicomplexans and related alveolates, such as cortical alveoli, underlying microtubular corset, and an apical microtubular cone (Moore et al., 2008; Obornı k et al., 2011), but also possesses a single four mem-brane–bound plastid.

New tech uncovers the hidden life of ‘dead’ coral reefs. Chromera velia was discovered a decade ago associated with stony corals in the Great Barrier Reef and Sydney Harbour, Australia. This unicellular alveolate possesses housekeeping genes and ultrastructural features typical of apicomplexans, and has active photosynthetic pathways related to dinoflagellates. Abstract Insects rely on the innate immune system for defense against pathogens, some aspects of which are under hormonal control. Here we provide direct experimental evidence showing that the juvenile hormone-binding protein (mJHBP) of Aedes aegypti is required for the regulation of innate immune responses and the development of mosquito blood cells (hemocytes).

Velia is the Italian (and Latin) name of the ancient town of Elea (Ancient Greek: Ἐλέα) located on the territory of the comune of Ascea, Salerno, Campania, Italy in a geographical sub-area named Cilento.Originally founded by the Greeks as Hyele (Ancient Greek: Ὑέλη) in Magna Graecia around 538–535 BC, it is best known as the home of the philosophers Parmenides and Zeno of Elea, as

These are almost certainly contaminations introduced at the commercial sequencing facility where our data was generated. We unfortunately did not detect them during the process of our previous analysis, owing to the limited sample of reference genomes for comparison in our data and the absence of a draft Chromera velia genome sequence. We have Chromera velia, also known as a "chromerid", [1] [2] is a unicellular photosynthetic organism [3] in the superphylum Alveolata.It is of interest in the study of apicomplexan parasites, specifically their evolution and accordingly, their unique vulnerabilities to drugs. Since its first description, Chromera velia has attracted keen interest as the closest free-living relative of parasitic Apicomplexa. The life cycle of this unicellular alga is complex and involves a motile biflagellate form. Flagella are thought to be formed in the cytoplasm, a rare phenomenon shared with Plasmodium in which the canonical mode of flagellar assembly, intraflagellar transport

Chromera velia (C.Velia) is a newly discovered algal species in Australia (Moore et al., 2008). It possesses photosynthetic characteristics similar to photosynthetic dinoflagellates, but has physiological and molecular features of non-photosynthetic apicomplexan parasites. 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 digalactosyldiacylglycerol in C. Velia and localize Chromera velia and Vitrella brassicaformis are photoautotrophic alveolates recently found in Australian corals and shown to be the closest known photosynthetic relatives of apicomplexans.

Immunogen. KLH-conjugated synthetic peptide well conserved PEPC1 and sequences from different plant species including Arabidopsis thaliana Q9MAH0, At1g53310 (PEPC 1), Q84VW9, At3g14940 (PEPC 3). The peptide chosen to elicit this antibody is also perfectly conserved in bacterial type of this enzyme NP_177043.2 (PEPC 4). For Zea mays, the peptide is converved in PEP1 and PEP4 isoforms.

However, only two studies to-date have investigated the symbiotic nature of Chromera velia with corals and thus little is known about the coral-chromerid relationship. Furthermore, the response of chromerids to environmental stressors has not been examined. Here we tested the performance of four chromerid strains and the common dinoflagellate پلاسمودیوم، توده‌ای سیتوپلاسمی است که تعداد زیادی هسته دارد.احتمالاً این توده‌ها تقسیم میتوز بدون سیتوکینز داشته‌اند. پلاسمودیوم نام یک سرده از آغازیان هاگ‌دار نیز می باشد و ازجمله معروف‌ترین هاگ‌داران انگلی است. The molecular response mechanisms of algae to Hg exposure are mostly unknown. Here, we combine physiological, biochemical, and transcriptomic analysis to provide, for the first time, a comprehensive view on the pathways activated in Chromera velia in response to toxic levels of Hg.

In order to estimate the possible structure of the unknown carbonyl carotenoid related to isofucoxanthin from Chromera velia denoted as isofucoxanthin-like carotenoid (Ifx-l), we employed steady-state and ultrafast time-resolved spectroscopic techniques to investigate spectroscopic properties of Ifx-l in various solvents. The results were compared with those measured for related carotenoids

[Extract] The discovery of a novel alga, Chromera velia, has generated much interest because it is a missing link between the non-photosynthetic apicomplexan parasites and dinoflagellates, which includes the coral endosymbiont Symbiodinium (Moore et al. 2008). Janouškovec, this new algal species has only been found in association with corals, having now been isolated from multiple coral

Adshelp[at]cfa.Harvard.Edu The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A Chromera velia has added the first nonparasitic autotroph with a photosynthetically active plastid to the base of the apicomplexan phylum (Moore et al. 2008). At least one more photosynthetic basal apicomplexan has since been described, and collectively, they are currently designated as ‘‘chromerids’’ (Janouskovec et al. 2010; Obornik The discovery of Chromera velia, a free-living photosynthetic relative of apicomplexan pathogens, has provided an unexpected opportunity to study the algal ancestry of malaria parasites.In this work, we compared the molecular footprints of a eukaryote-to-eukaryote endosymbiosis in C.
