1a–h), a dominant species on Okinawan reefs. Coral reefs are estimated to harbour around one third of all described marine species6, and their productivity supports around one quarter of marine fisheries, but declines in coral abundance and wholesale loss of reef habitats are one of the most pressing environmental issues of our time. The overall target coverage is similar between putative A. millepora and A. digitifera (2.0) proteins with slightly better performance of A. millepora proteins at the high coverage end (fig. Reef-building Scleractinia first appeared in the fossil record in the mid-Triassic (approximately 240 million years ago)5, but were already highly diversified, suggesting much earlier origins. The genome browser is accessible at http://marinegenomics.oist.jp/acropora_digitifera (Supplementary Fig. Biophys.

(f, g) Circos plots showing relationships between the A. millepora and A. digitifera genomes. Acropora species is the dominant reef‐building coral of the Indo‐Pacific 7, and Acropora digitifera (Staghorn coral) is the dominant coral on Okinawan reefs. AGRF acknowledges support from Bioplatforms Australia through funding from the National Collaborative Research Infrastructure Strategy. The immune gene repertoire encoded in the purple sea urchin genome. Likewise, the Acropora repertoire of NACHT/NB-ARC domains, which are characteristic of primary intracellular pattern receptors20, is again highly complex: an order of magnitude more NACHT/NB-ARC domains are present in coral than in other animals (Supplementary Table 11), and some of these cnidarian proteins have novel domain structures (Supplementary Fig. S1−S12. Biol. AUGUSTUS 2.0.4 was trained on the 877 EST assemblies recommended by PASA38 for this purpose. The genome was sequenced to approximately 151-fold coverage (Supplementary Table 1), enabling the generation of an assembly comprising a total of 419 Mbp (Supplementary Tables 2–5; contig N50 = 10.7 kbp and scaffold N50 = 191.5 kbp; Supplementary Fig. & Endo, K. Skeletal matrix proteins of invertebrate animals: comparative analysis of their amino acid sequences. Disordered Avg. The mitochondrial genome sequence was identified from the assembly and compared with known Acropora mitochondrial genomes. CAS 1b). 2015). As corals are particularly susceptible to bleaching when exposed to both raised temperatures and high solar radiation2,4, one intriguing question is how corals protect themselves against ultraviolet damage. Gaps inside the scaffolds were closed with Illumina paired-end data using GapCloser34. Genome and EST sequencing and assembly: C.S., T.K., E.S., K.H., M. Fujie, M. Fujiwara, M.T., M.H., A.F.

Sperm were collected from a single A. millepora colony at Magnetic Island, Queensland (19°08′S, 146°50′E), snap frozen in liquid nitrogen and stored at −80 °C until needed. De novo identification of repetitive elements was conducted on the A. millepora genome assembly. 1 a,b) was sequenced and assembled using a whole-genome shotgun sequencing approach based 140.6 million (PE, MP, and fosmid) paired-end reads (supplementary table S1, Supplementary Material online). Although extensive transcriptomic data are available for various Acropora spp13, we could find no evidence for a Cbs transcript in any of these. 4, 122–131 (2001), Article 32). Each purple line crossing the circle represents a unique alignment and the units on the periphery represent 1 Mb. The coral genome provides a platform for understanding the molecular basis of symbiosis and responses to environmental changes. Google Scholar, Putnam, N. H. et al. Recently a short (four-step) pathway encoded by a gene cluster (DHQS-like, O-MT, ATP-grasp and NRPS-like) (Fig. Fittingly, the first coral genome to be sequenced was Acropora digitifera; the availability of this whole-genome sequence (Shinzato et al.

The Acropora Digitifera Genome The genome of A. digitifera , decoded using next-generation sequencing technology, is ~420-Mbp in size, 39% G+C, and contains 23,668 predicted protein-coding loci ( … They are under threat because the scleractinian corals at their core are susceptible to ocean acidification and rising seawater temperatures. (a) An example of a PAP region lacking coverage. pFosill vectors were supplied by Andreas Gnirke and MP fosill libraries were constructed as described by Williams et al. Yet, there is no genetic evidence to support this hypothesis. Here we decoded the 420-Mbp genome of the reef-building coral Acropora digitifera, with the aim of providing a platform for understanding the molecular basis of symbiosis and responses to environmental change. Molecular phylogenetic analyses based on an alignment of 94,200 amino acid positions suggest a divergence time of Acropora and Nematostella between 520 to ∼490 million years ago (the late Cambrian or early Ordovician) (Fig. Coral reefs are among the most biologically diverse ecosystems on the planet and are of great economic importance. Some coral genera are particularly sensitive to stress and, among these, Acropora is of particular significance because this is the dominant genus of reef-building corals in the Indo-Pacific. This licence does not permit commercial exploitation, and derivative works must be licensed under the same or similar licence. A primary approach to the identification of putative orthologues of A. digitifera genes was reciprocal BLAST analysis. Science 301, 929–933 (2003), ADS Meanwhile, the gene model presented here is of considerably higher quality than the v1.0 models provided by Shinzato et al. (PDF 16049 kb). (2020), Frontiers in Marine Science Among these, 82% were aligned uniquely with an average length of 1,550 bp and an average identity of 94.91%. The authors declare no competing financial interests. Division of Ecology and Evolution, Research School of Biology, Australian National University, Acton, Australian Capital Territory, Australia. Hence, MAA synthesis in corals and other cnidarians is not symbiont dependent. 36, D480–D484 (2008), Shick, J. M. & Dunlap, W. C. Mycosporine-like amino acids and related Gadusols: biosynthesis, acumulation, and UV-protective functions in aquatic organisms. Corals inhabit environments where they are frequently exposed to high levels of solar radiation, and analysis of the Acropora genome data indicates that the coral host can independently carry out de novo synthesis of mycosporine-like amino acids, which are potent ultraviolet-protective compounds. Nature 2008) and CRISPR/Cas9 (Cleves et al. Climate change, human impacts, and the resilience of coral reefs. d–h, Eggs, embryos, larva and primary polyp of A. digitifera, from which messenger RNA was extracted for transcriptome analyses. The genome of A. digitifera, decoded using next-generation sequencing technology, is ~420-Mbp in size, 39% G+C, and contains 23,668 predicted protein-coding loci (Shinzato et al., 2011).The coral gene set is comparable in size and composition to those of Nematostella vectensis (Putnam et al., 2007) and Hydra magnipapillata (Chapman et al., 2010). 304, 11–17 (2003), Dayarian, A., Michael, T.

In terms of the apparent expansion and divergence of NACHT-encoding genes, the coral resembles amphioxus21, the sea urchin22 and angiosperms23. A number of candidate organic-matrix proteins were identified in Acropora (Supplementary Fig. A set of gene model predictions (the A. digitifera Gene Model v. 1) was generated mainly by AUGUSTUS29, and a genome browser has been established using the Generic Genome Browser (GBrowser) 2.17. On average, there are seven exons per gene, and the mean transcript length is 1,818 bp. Bioinformatics 14, 755–763 (1998), Larkin, M. A. et al. Also know as '(German: Kleinpolypige Steinkoralle)'. 2008. Approximately 93% of the A. digitifera genes have matches in other metazoans (Supplementary Fig. Nature 476, 320–323 (2011). Among the 248 core eukaryotic genes from CEGMA, 65% and 92% of these genes are present in full in the A. millepora genome assembly and predicted transcripts respectively. Molecular phylogenetic analyses of the genes are shown in Figs. Article The implied earlier origin of Scleractinia indicates that corals have persisted through previous periods of major environmental change, including the mass extinction event at the Permian/Triassic boundary, when global CO2 and temperature were much higher than at present. The genome of the branching coral Acropora digitifera appears online today in … 94,200 aligned amino acid positions of proteins encoded by 422 genes were obtained from the sponge Amphimedon queenslandica, from the cnidarians A. digitifera, Nematostella vectensis and Hydra magnipapillata, and from the triploblasts Tribolium castaneum, Drosophila melanogaster, Branchiostoma floridae, Danio rerio and Homo sapiens. In terms of these statistics, the A. millepora genome data therefore outperform the updated (v2.0) NCBI A. digitifera genome release. Sequencing and de novo analysis of a coral larval transcriptome using 454 GSFlx. Among corals, early development has been most extensively documented in A. millepora (e.g., Hayward et al. Article On the basis of flow cytometry, the A. digitifera genome is approximately 420 Mbp (Supplementary Figs 1 and 2) and is therefore similar in size to that of the sea anemone Nematostella9. The longest five reference scaffolds from (f) A. millepora (orange) or (g) A. digitifera (blue) are arranged around the circumference of the figure. To understand better the molecular mechanisms underlying coral biology, here we decoded the approximately 420-megabase genome of Acropora digitifera using next-generation sequencing technology. The updated A.digitifera genome assembly (2.0, NCBI accession GCF_000222465.1) and annotation (NCBI annotation release 100) were downloaded from the NCBI FTP site (ftp://ftp.ncbi.nih.gov/genomes/Acropora_digitifera; last accessed February 28, 2019). Sci. High-molecular-weight genomic DNA was prepared using a method based on that described by Blin and Stafford (1976). 1e). Published by Oxford University Press on behalf of the Society for Molecular Biology and Evolution. In addition, the coral innate immunity repertoire is notably more complex than that of the sea anemone, indicating that some of these genes may have roles in symbiosis or coloniality. Science 317, 86–94 (2007), Margulies, M. et al. Bottom, the presence of corresponding genes in various organisms is indicated (+). Whole-genome alignments between A. millepora and A. digitifera were performed using the NUCmer module of MUMmer v4.0.0beta2 (Marçais et al. The A. millepora mitochondrial genome was assembled to a single scaffold, whose length is consistent with that from other Acropora spp. See supplementary table S11, Supplementary Material online, for more detail. 2019; Shumaker et al. (2012). The coral repertoire of genes with predicted roles in skeleton deposition is of particular interest given the likely impact of ocean acidification resulting from rising atmospheric CO2 on coral calcification. Selection of conserved blocks from multiple alignments for their use in phylogenetic analysis. Genome sequencing in microfabricated high-density picolitre reactors. (2021), G3: Genes|Genomes|Genetics The completeness of the genome assembly and gene model were assessed using the CEGMA (Parra et al. Coral bleaching: the winners and the losers. volume 476, pages320–323(2011)Cite this article. In terms of completeness, the genome assembly and associated gene predictions are of similar quality to the recent NCBI-generated version (2.0) of the A. digitifera genome. This was carried out on the basis of mutual best hit in BLAST analyses for human, mouse, or Drosophila genes against the A. digitifera gene models (BLASTP) or the assembly (BLASTN). A genome size estimate of 470 Mb obtained from kmer analysis of short-read data with sga.preqc (24) was close to the final assembly Approximate divergent times of the occurrence of basal chordates and divergence of vertebrates lineages are shown. Among the core set of conserved proteins, we found an emphasis on Science 318, 1737–1742 (2007), Carpenter, K. E. et al. NCBI; Skip to main content; Skip to navigation; Resources.

We were unable to find any Symbiodinium DNA sequences in the coral genome, hence there is as yet no evidence for horizontal gene transfer from symbiont to host (Supplementary Fig. 2011), and additional coral genomic data are becoming available (Prada et al. The greater complexity of the coral innate immunity network may in part reflect adaptations associated with the symbiotic state and coloniality. The sequences were analysed using maximum likelihood methods, with the plant Arabidopsis thaliacia and the choanoflagellate Monosiga brevicollis serving as outgroups. As another approach to comparing the A. millepora and A. digitifera genome sequences, similarity of protein-coding sequences was evaluated. 23b). https://doi.org/10.1038/nature10249, Developmental & Comparative Immunology The classified transposable elements represent over 45 different families and show a slight preference for class I retrotransposons (supplementary table S8, Supplementary Material online). BMC Bioinformatics 11, 345 (2010), Boetzer, M. et al. Both the assembled A. digitifera and A. millepora mitochondrial genomes differ from the reference A. digitifera sequence by ∼0.2%, which could reflect assembly artifacts originating from sequencing errors. In addition, Illumina 50-bp paired-end RNA-seq sequencing was performed. Unclosed gaps (Ns) comprise 9.72% of the genome sequence and the average GC content is 38.85% (table 1 and supplementary table S5, Supplementary Material online). 2 and Supplementary Figs 9–12) has been demonstrated to be both necessary and sufficient in the cyanobacterium Anabaena variabilis to convert pentose-phosphate metabolites to shinorine, a photo-protective MAA17. You are using a browser version with limited support for CSS. Opin. To obtain Functional annotation was performed by homology searching to match predicted proteins to the PFAM-A protein domain and the Kyoto Encyclopedia of Genes and Genomes (Kanehisa et al. 6). Molecular phylogenetics indicate that the coral and the sea anemone Nematostella vectensis diverged approximately 500 million years ago, considerably earlier than the time over which modern corals are represented in the fossil record (∼240 million years ago)5. The association is fragile, however, and collapses under stress. The acropora digitifera genome.
