skeletonema costatum genome

Sc singlet genes represents the number of non-orthologous genes in Sc, and passed to the list of Sc-specific genes. Lieselot Balduyck, ... Imogen Foubert, in Handbook of Marine Microalgae, 2015. On the other hand, the fat-soluble vitamin E (tocopherol) is also produced in high amounts by microalgae such as Dunaliella tertiolecta and Tetraselmis suecica (Carballo-Cardenas et al., 2003). First, we changed the temperature condition from cold (10 °C) to normal (18 °C), and an even higher temperature (28 °C) where the red tide is likely to occur. Taken together, we conclude that genome assembly by Platanus would be adopted. 2014;30(1):31–7. Article  Google Scholar. Not applicable. The chain-forming diatom S. costatum is characterized by cylindrical cells containing two chloroplasts where the face of the valve margin bears long processes (costae), which connect with processes originating from the adjacent daughter cell valve face (Sarno and Kooistra, 2005). Genes involved in these pathways were extracted, and gene expression intensities (FPKM) of these genes were used for heatmap analysis. We appreciate the staff of Nagahama Institute of Bio-Science and Technology Genomic diversity laboratory, Ikuyo Takemura for assistance with data analysis. Finally, we changed the nutritional conditions and extracted highly and differentially expressed genes in good condition for the red tide. Dari pembelahan sel tersebut akan dihasilkan 2 sel yang ukurannya lebih kecil daripada sel induknya. Oxford: Blackwell Scientific Publ. Protist. (2016) studied the bioactivity of five north Atlantic marine diatoms, Attheya longicornis, Chaetoceros socialis, Chaetoceros furcellatus, Skeletonema marinoi, and Porosira glacialis with different light and temperature treatments. It is especially abundant during spring bloom, when densities of million of cells per litre is reported. Ingebrigtsen et al. Marinobacter sp. Part of Several diatom species are also known to have antibacterial activity. Kooistra WHCF, Sarno D, Balzano S, Balzano S, Gu H, Andersen RA, Zingone A. Cell division and Mitotic nuclear division were also shown from the common genes for harmful algal bloom. These discussions led to the conclusion that EOC production is normal in healthy phytoplankton (Sharp, 1977; Fogg, 1983). We use cookies to help provide and enhance our service and tailor content and ads. 3a). From screening studies, it has been shown that crude extracts of the diatom S. marinoi, cultured under phosphate and nitrogen starvation, displayed antibacterial activity against S. aureus with extracts at a concentration of 50 μg/mL (Lauritano et al., 2016). The members of the class Bacillariophyceae can be found in freshwater and marine environments, and are mainly unicellular, although some are colonial. Tocopherols are more thermostable and lipophilic and are therefore important for the stability of microalgal oils. Hildebrand and Dahlin (2000) and Hildebrand (2005) first described NO3 and NH4 transporter genes (hnat and amt, respectively) in Cylindrotheca fusiformis. A broader list of bacteria and their targets is presented in Mayali and Azam (2004). Despite the fact that the pennate and centric lineages have only been diverging for 90 million years, their genome structures are dramatically different, and a substantial fraction of genes (40%) are not common in these representatives of the two lineages. SolexaQA: At-a-glance quality assessment of Illumina second-generation sequencing data. AN ASSESSMENT OF THE TAXONOMY OF S. COSTATUM-LIKE SPECIES WITH THE DESCRIPTION OF FOUR NEW SPECIES1 Diana Sarno,2 Wiebe H. C. F. Kooistra Stazione Zoologica ‘‘Anthon Dohrn,’’ Villa Comunale, 80121 Naples, Italy 2008;456:239–44. To obtain genome and gene model of Sc with higher quality, we tried to use four different genome assembly software, WGS, Platanus, Allpaths-LG, SOAPdenovo2, and SPAdes. Marine phytoplankton would seem appropriate for first consideration. A good example of these tests can be found in ISO (1995) for seawater (involving Phaeodactylum tricornutum or Skeletonema costatum) and in OECD (1998) for freshwater environments (involving Raphidocelis subcapitata, formerly known as Selenastrum capricornutum and Pseudokirchneriella subcapitata, Scenedesmus subspicatus, or Chlorella vulgaris). Correspondence to Basic local alignment search tool. Nevertheless, 48-h spore germination success and length of gametophyte germ tubes of the giant kelp Macrocystis pyrifera have been developed as marine standardized toxicity tests (OEHHA, 2004), and, in Australia and New Zealand, assays related to the fertilization of Hormosira banksii, and the germination and growth of Ecklonia radiata have also been standardized (ANZECC and ARMCANZ, 2000). For both short- and long-term fish studies (Figure 9.1), Pimephales promelas, Oncorhynchus mykiss, and Danio rerio have been the most frequently used species (more than 10% of studies) (Tarazona et al., 2014). A biological function for cadmium in marine diatoms. For the genome size estimation, we used KmerGenie that could estimate the best k-mer length for genome de novo assembly [34]. Terms and Conditions, Freshwater species used in acute tests include the rainbow trout, Onchorynchus mykiss; brook trout, Salvelinus fontinalis; channel catfish, Ictalurus punctatus; fathead minnow, Pimephales promelas; and bluegill, Lepomis macrochirus; while saltwater fish include the sheepshead minnow, Cyprinodon variegates; mummichog, Fundulus heteroclitus; longnose killifish, Fundulus similis; silverside, Menidia spp. In the analysis, the function related to oxidative stress was significantly enriched in the common genes for the harmful algal bloom and the Sc-specific genes. Enrichment analysis of these 233 genes showed that the oxidation-reduction process including some other photosynthesis related process response to cadmium ion, and response to cytokinin were significantly enriched again. The n-hexane extracts exhibited a growth inhibition of S. aureus, B. subtilis and E. coli with a MIC of 250 μg/mL. These sequence raw reads were deposited to DDBJ DRA sequence read archive (ID:DRA007346). 17.4) of physiological response may have a molecular basis. For aquatic systems, plants, invertebrates and vertebrates are tested. e Gene set enrichment analysis of Sc-duplicated genes. The red tide is named after the color of the water, which changes to reddish brown, depending on the pigment of plankton. Small-sample estimation of negative binomial dispersion, with applications to SAGE data. 1 Coronavirus: Find the latest articles and preprints The centric diatoms Skeletonema costatum, Chaetoceros muelleri, and Thalassiosira pseudonana are cultivated at commercial scales (Table 2); distinctive diagnostic features will be briefly described here. Orthofinder could find orthologues and orthogroups infers rooted gene trees for all orthogroups and infers a rooted species tree for the species being analysed. Important microalgal carotenoids include lutein, astaxanthin, fucoxanthin, and β-carotene. In a review, however, Mayali and Azam (2004) concluded that the evidence for algaecidal bacteria influencing the decline of blooms may be circumstantial due to limitations of current methods. In this study, we sequenced the whole genome of Sc, and performed a comparative genomic analysis of the constituent species causing harmful algal bloom and out-group, Vitrella brassicaformis (Vb), which is a single-cell organism belonging to chromomers that are close to Stramenopile involving Sc, Tp, and Pt [24]. Bioinformatics. Spatial differences—among latitudes or between neritic shelf waters and the open oceanic systems— probably also attest to the functional differentiation of the phytoplankton. For this purpose, we performed a transcriptome analysis that could comprehensively analyze the expression status of genes in various conditions imitated for the harmful algal bloom causing situations. Lehahn Y, et al. The presence of extracellular organic carbon (EOC) compounds in the aquatic realm has long been known. To establish whether GS II and GS III might have these different functions in diatoms, Takabayashi et al (2005) measured expression of the gene responsible for GS II (gln II) in Skeletonema costatum cells grown with either elevated NO3, or NH4 or both forms of DIN. Nevertheless, the apparent functional and morphological correlations have scarcely been quantified. We searched repeat sequences by RepeatMasker and found that Sc possessed many number of simple repeats comparing with other diatoms, but possessed less SINE and LINE (Additional file 1: Table S1, sheet1-Repetitive element). Li et al. Organisms used include algae such as the freshwater algae, Pseudokirchneriella subcapitata, Anabaena flos-aquae, Microcystis aeriginosa, and Navicula peliculosa and the saltwater algae, Chlorella spp., Chlorococcum spp., Dunaliella tertiolecta, Isochrysis galbana, Nitzchia closterium. We estimated the ortholog gene group for S. costatum, T. pseudonana, P. tricornutum, V. brassicaformis using Orthofinder (v1.0.7) [42] with default parameters. Previously, a marine bacterial strain, Halobacillus sp. On the other hand, both in living cells and dried biomass, several antioxidant molecules protect the cell content against oxidation. Areas of frontal activity and of surface upwellings of the deep oceanic circulation currents tend to combine intensive mixing with renewed resources and to select species in the C-R intermedium through much of the year: Gyrodinium spp., Alexandrium tamarense, Thalassiosira leptoporous can be typical assemblage members. We obtained a total of 6.3Gbps from gDNA of S. costatum and used them for de novo assembly. To be able to use gene expression as a proxy for species-specific flux or productivity, there first needs to be sufficient sequence data and identification of genes involved in N uptake in target microbial cells expected in these upwelling systems. Black rectangle represents the number of differentially expressed genes under different temperatures (up), different light conditions (middle), and different nutrient condition (bottom). Sarno D, Kooistra WCHF, Balzano S, Hargraves PE, Zingone A. Diversity in the genus Skeletonema (Bacillariophyceae). strain MCTG268 isolated from the cosmopolitan marine diatom Skeletonema costatum AU - Gutierrez, Tony AU - Whitman, William B. 2015;31:3210–2. Bioinformatics. Kwon S-K, Park Y-K, Kim JF. There are two major diatoms have been sequenced, but more diatoms should be examined at the whole genome level, and evolutionary genome studies were required to understand the landscape of molecular mechanism of the harmful algal bloom. WGS contains 16 duplicate genes that might be derived from redundant genome assembly as the assembled genome size by WGS is much larger than estimated from k-mer analysis. Evidence of a similar coherence among morphological form, physiological performance, and population responses to environmental forcing was presented in Margalef's (1978) seminal discussion of plankton life-forms, while the insights underpinning the “mandala” model (Margalef et al., 1979) continue to intrigue plankton ecologists. 3a). Based on 16S rRNA gene sequence identity, the closest type species is Marinobacter algicola strain DG893, which had also been isolated from a laboratory culture of eukaryotic … 2010;11:485. Traditional methods, such as tracer techniques (Chapter 31 by Lipschultz, this volume) or measuring enzyme assimilation rates (e.g., Berges, 1997; Berges and Harrison, 1995; Berges et al., 1995; Slawyk et al., 1997; Chapter 32 by Berges and Mulholland, this volume) provide nitrogen uptake/assimilation (productivity) rates, but do not identify the major players involved in mass transformation, or the physiology of the phytoplankton involved. consists of a series of genetically and morphologically distinct species [13,14,15,16]. The centric diatom C. muelleri is frequently used in aquaculture, as the cells are weakly silicified and the cells are solitary. Arch Protistenkd. Araújo, Ignacio Moreno-Garrido, in Handbook of Marine Microalgae, 2015. The completed Pt genome is approximately 27.4 megabases (Mb) in size, which is slightly smaller than Tp (32.4 Mb), and P. tricornutum is predicted to contain fewer genes (10,402 as opposed to 11,776, Table 1). nov. J Phycol. To elucidate the molecular mechanism of the harmful algal bloom, it is necessary to analyze what kind of fluctuation of Sc genes occurs under the harmful algal bloom condition. Google Scholar. On the contrary to the conserved genes among species, there are genes only found in Sc. Distribution of species reported by Tarazona et al. Science. Regarding Pt, it is known that the putamen is not formed much compared with other diatoms, consequently less number of silicate-related genes seemed reasonable. An important class of low-molecular-weight antioxidants, present in microalgae, are antioxidant vitamins. Seven genes of silicate and silaffin, Sil1, Sil2, Sil3, SIT1, SIT2, SIT3, and TPSIL2, were extracted from the NCBI DB. @article{osti_1378996, title = {Genome Sequence of Marinobacter sp. We then compared the genome and gene model of Sc with other diatoms and Vb, and it was suggested that Sc had larger genome size than other diatoms, and the number of genes was also larger than that of other diatoms (Additional file 1: Table S1). In the transcriptome study, we observed significant enrichment of genes related to oxidative stress in the different conditions. Such Sc-specific genes can be categorized to two types, duplicated and singlet genes. As shown in Table 2, the genome of Sc has many contigs, and a large number of fragment sequences are generated, which might be caused by fragmentations of contigs and over-estimation of genes. Karentz D, Smayda TJ. Numerous studies and observations have been made regarding the interaction between algaecidal bacteria and bloom-forming species. Kirsten Heimann, Roger Huerlimann, in Handbook of Marine Microalgae, 2015. As a result, many of Oxidation-reduction process, Response to cytokinin belonged to the common group of algae (Sc, Tp, Pt, Vb) (Fig. Genome annotations. in The Biology of Diatoms, ed. Diatom common genes were preserved about 45% from the number of STPV and STP genes that may have the essential role in the functionality of the harmful algal bloom. Based on the estimation of silicate and silaffin genes in the four species (Additional file 1: Table S1, sheet4-#silicate & silaffin), Tp possessed higher number of genes comparing with other species, whereas Sc has also high number of silicate-related genes. Microalgae reduce (lipid) oxidation in living cells using two strategies: antioxidant enzymes and antioxidant molecules. Manage cookies/Do not sell my data we use in the preference centre. Morphological and genetic variation within the diatom Skeletonema costatum (Bacillariophyta): evidence for a new species, Skeletonema pseudocostatum. Cultures of these microorganisms are standardized and can be easily maintained in the laboratory all year round, although this is not the case for macroalgae that are underrepresented among aquatic toxicity test organisms (Han et al., 2011). Bioassay data treatments for microalgae are clearly and substantially discussed in the reference work of Nyholm (1990). The source of NH4 may be externally supplied or internally as a product of NO3 reduction or photorespiration. or needle-like (Rhizosolenia) diatoms with high surface-area-to-volume ratios and antennal enhancement. The genome size of Sc was larger than other diatoms, so that we checked if the reason for the larger-sized genome is due to repeat sequences. A total of 31,964 protein-coding genes were predicted in the S. obliquus AS-6-11 genome (Table 2).The predicted gene number of S. obliquus AS-6-11 genome is dramatically higher than the other Scenedesmus strains (Table 1).According to the Non-redundant protein (NR), SWISS-PROT, and Pfam protein families databases, 19,847, 13,099, and 13,612 proteins … Genome size estimation by k-mer analysis and the common eukaryotic genes conservation rate. Skeletonema costatum | Diatom Order: Biddulphiales Family: Thalassiosiraceae Click on illustration to enlarge . 1995;268:375–9. 2010;76(5):1661–8. Much effort has been devoted to the physiological response of marine diatoms to ambient P change, however, the whole-genome molecular mechanisms are poorly understood. The whole genome of Skeletonema costatum, S c was de- termined by Illumina Hiseq 2000, the next generation Fig. In the orthologous gene analysis, we estimated orthologous gene groups using similar length of genes, representing reliable orthologous gene sets. d Gene set enrichment analysis of Sc-specific genes. For the culture conditions for this experiment, we changed temperatures, light, and nutrition to test which genes are responsible for the environmental changes. The genome of the diatom Thalassiosira pseudonana: ecology, evolution, and metabolism. These tests focus on development and growth during the first 30–90 days of development from the egg. However, harmful algal bloom as known as red tide is a major problem in environment and fishery industry. Temperature and seasonal occurrence patterns of 30 dominant phytoplankton species in Narragansett Bay over a 22-year period (1959-1980). Thus, in spite of their limitations, microalgal bioassays in batch cultures can provide useful and comparable information about the toxicity of substances and effluents. From the pioneering Algal Assay Procedure Bottle Test (US EPA, 1971), designed in order to detect aquatic eutrophication, many guidelines for microalgal toxicity tests have been developed (Rand, 1995).

In Korea, the distribution and lethality of algaecidal bacteria against Cochlodinium polykrikoides were studied in a local bay. 2c, d, e, Additional file 1: Table S1, sheet3-Duplication_list). The big, buoyancy-regulating, stress-tolerant, S-species of diatom (Ethmodiscus) and dinoflagellate (Pyrocystis) are at the culmination of this sequence. Imai (1997) examined several strains of Alteromonas sp. There is an estimate for global net primary production (NPP) of 104.9 petagrams of carbon per year, of which 46% is oceanic and 54% is terrestrial [11]. (1992) in a laboratory study to simulate upwelling measured the response of the gene for the major NO3 assimilation enzyme, nitrate reductase (NaR) in light- and N-limited diatom cells of Skeletonema costatum when given an increase in light and NO3 availability. Furthermore, oxidative stress-related genes were found in Sc-specific genes; the common genes for the red tide. To perform gene set enrichment analysis, GO annotation is required, so we first conducted blast search against the DB of Arabidopsis thaliana, which is the model organism with annotation for gene ontology categories. J Oceanogr. Gallagher, J.C. (1980) Population genetics of Skeletonema costatum (Bacillariophyceae) in Narragansett Bay Journal of Phycology 16: 464-474 Hasle, G.R. As results, we found that both evolutionary genomic and comparative transcriptomic studies revealed genes for oxidative stress response and response to cytokinin is a key for the proliferation of the diatom. KM and TG conducted library construction and sequencing experiment using Illumina sequencer and data processing from raw data to qualified sequences. The valves of vegetative cells are elliptical (4.5–20 μm in diameter) in valve view with four long setae (one on each corner of the epi- and hypovalves, respectively), while auxospores are spherical (6 μm in diameter) and more heavily silicified, but nonetheless unornamented by light and scanning electron microscopy (Reinke, 1984). This species is more likely to bloom under high temperature and high illumination, with optimal conditions at 25 °C and Close Irradiance. Cytokinin has been shown to be involved in cell proliferation in other algae. As a unique feature of diatom cells, they are enclosed by a cell wall made of silica, called a frustule, and their vegetative cells reproduce by asexual cell division. Diatoms are a unicellular, diploid, photosynthetic, eukaryotic microalgae, which distribute throughout marine and freshwater systems [1], and the group exists in a huge variety of shapes and sizes. 2003;17(4):1103. Genome Biol. Appl Environ Microbiol. I. Skeletonema subsalsum (A.Cleve) Bethge Phycologia 14 :283-297 A. thaliana ID was then converted to RefSeq protein ID using BioMart to perform gene enrichment analysis by DAVID. Long time-series observations in population dynamics of the harmful diatom Eucampia zodiacus and environmental factors in Harima-Nada, eastern Seto Inland Sea, Japan during 1974-2008. For instance, Furuki and Kobayashi (1991) noted that certain bacteria can both promote and inhibit the proliferation of Chatonella sp. (duckweed) is also used. 1990;215:403–10.
