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. 10, 311–336 (2006), Fukuda, I. et al. Because of the ecological significance of Acropora, the complete genome of Acropora digitifera was the first coral genome sequenced (Shinzato et al. For each reference scaffold, the top three scaffolds containing the most alignments in the other genome are shown. The 454 shotgun and paired-end reads were assembled de novo by GS De novo Assembler version 2.3 (Newbler, Roche)10 in heterozygotic mode with adjusted algorisms to reflect an increase in the expected variability in sequence identity. (zooxanthellae), these resources will together provide additional perspectives on the symbiosis and a powerful resource for understanding the response of the holobiont to environmental stresses such as raised seawater temperatures or ocean acidification. See supplementary table S9, Supplementary Material online, for more detail. 2001), and therefore likely to reflect near maximal levels of divergence within the genus (supplementary table S6, Supplementary Material online). 1e).

Published by Oxford University Press on behalf of the Society for Molecular Biology and Evolution. 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 ( … The insert sizes ranged between 150 bp and 35 kb. The version described in this article is version QTZP01000000. 9, 10 Based on genome‐wide analysis, Shinzato et al. RNA was extracted as previously described (Moya et al. The coral seems to have lost a key enzyme of cysteine biosynthesis, so may be dependent on its symbionts for this amino acid. 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. On average, there are seven exons per gene, and the mean transcript length is 1,818 bp. Using the Acropora digitifera genome to understand coral responses to environmental change. D. Rokhsar and J. Chapman are acknowledged for suggestions on sequence assembly and gene prediction. Article  These factors have led to members of this genus often being the subjects of investigation into coral responses to various physical and biological stressors. Opin. 2002, 2004, 2015) and molecular technologies, including in situ hybridization (e.g., Grasso et al. 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 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. 2017) databases. Dev. 27, 221–224 (2010). 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. Macey, M. G. ) (Humana, 2007), Li, R. et al. This counter intuitive result reflects the generic problems associated with erroneous gene models generated from draft genome assemblies (Zhang et al. Genome Biol. All Resources; Chemicals & Bioassays. Of the other Acropora species for which whole mitochondrial sequences are available, A.tenuis is the most divergent (99.32% identity with the A. digitifera reference); this species is always well resolved in molecular phylogenies (see, e.g., van Oppen et al. (a) An example of a PAP region lacking coverage. The symbionts confer on the coral holobiont the ability to fix CO2 and to deposit the massive aragonite (a form of calcium carbonate) skeletons that distinguish reef-building corals from other anthozoans such as sea anemones. BUSCO analysis iden-tified a near complete 91.8% set of core metazoan genes including a small fraction that were duplicated (2.6%) or fragmented (1.8%). Sign up for the Nature Briefing newsletter — what matters in science, free to your inbox daily. The A. millepora mitochondrial genome was assembled to a single scaffold, whose length is consistent with that from other Acropora spp. 2007). The classified transposable elements represent over 45 different families and show a slight preference for class I retrotransposons (supplementary table S8, Supplementary Material online). On the basis of the alignment data sets, phylogenetic trees were constructed by neighbour joining and/or maximum likelihood. 3). The sequences were analysed using maximum likelihood methods, with the plant Arabidopsis thaliacia and the choanoflagellate Monosiga brevicollis serving as outgroups. The read coverage (0 to 50) across the scaffold is shown in gray for a control and three samples. Corals are morphologically very similar to sea anemones, but their evolutionary origins are obscure. From the latter, 91% (5,187) were identified as putative noncoding transcripts by using CPC software (Kong et al. Genome Annotation De novo identification of repetitive elements was conducted on the A.milleporagenome assembly. While 69% of all transcripts (12,587) were clearly represented in the predicted Acropora proteome, the remaining 31% (5,677 transcripts) mapped only to the genome. The immune gene repertoire encoded in the purple sea urchin genome. 2001) that have diverged since the Oligocene (Santodomingo et al. Acropora digitifera [65]; the clownfish Amphiprion polymnus [66]; the sea star Protoreaster nodosus [67]; the bicolour damselfish Stegastes partitus [68]; and mussel Mytilus edulis [69]. 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. Despite the long evolutionary history of the endosymbiosis, no evidence was found for horizontal transfer of genes from symbiont to host.

The Acropora digitifera genome contains seven opsin genes and three cryptochrome genes (blue number shows A. digitifera gene number; red number, N. vectensis ). Surveys of the Acropora genome for specific groups of proteins associated with calcification, including the eukaryotic-type carbonic anhydrases24 are given in Supplementary Table 12. 1995). Bioessays 30, 1010–1018 (2008), Kanehisa, M. et al. Genome analysis has also revealed that adaptation of the microorganisms in the polluted environments is ensured at the genetic level by two component systems, chemotaxis, thermosensing and nutrient uptake and detoxification for responding to the corresponding environmental condition [10]. —(a–d) Images of the corals whose genomes were compared. If you find something abusive or that does not comply with our terms or guidelines please flag it as inappropriate. 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. Whole-genome alignment of the A. millepora and A. digitifera assemblies confirmed that the two species are closely related. A number of genes with putative roles in calcification were identified, and several of these are restricted to corals. https://doi.org/10.1038/nature10249, Developmental & Comparative Immunology Genome Res.

Although the analyses presented here do not rigorously exclude the presence of Cbs activity in Acropora, they raise the intriguing possibility of a metabolic basis for the obligate nature of symbiosis in Acropora; differences in dependency could potentially explain not only the phenomenon of symbiont selectivity, but also the high sensitivity of Acropora to environmental challenges. In terms of the apparent expansion and divergence of NACHT-encoding genes, the coral resembles amphioxus21, the sea urchin22 and angiosperms23. Acropora millepora Genome Assembly Zachary L. Fuller, Yi Liao, Line Bay, Mikhail Matz & Molly Przeworski August 2, 2018 Abstract The draft genome assembly of the staghorn coral Acropora millepora was constructed using a com-bination of PacBio reads and Illumina paired-end reads with 10X Chromium barcodes. 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.

To facilitate display, the scaffold names were shortened as “amil.Sc0000000” to am0, “amil.Sc0000001” to am1, and so on for A. millepora; “NW_015441060.1” to ad1060, “NW_015441061.1” to ad1061, and so on for A. digitifera. In addition to unfertilized eggs and adult samples, samples from six early life history stages were collected. Moreover, whereas a polymerase chain reaction (PCR) strategy confirmed the presence of Cbs in some other corals, Galaxea fascicularis, Favites chinenis, Favia lizardensis and Ctenactis echinata, no amplification products could be obtained for two different Acropora species (Table 1 and Supplementary Fig. study we have produced the genome of a robust coral, Stylophora pistillata, and compared it to the available genome of a complex coral, Acropora digitifera.

They are under threat because the scleractinian corals at their core are susceptible to ocean acidification and rising seawater temperatures. Sox genes in the coral Acropora millepora: divergent expression patterns reflect differences in developmental mechanisms within the Anthozoa. 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. For example, whereas a single canonical Toll/TLR protein is present in N. vectensis18, the Acropora genome encodes at least four such molecules, as well as five IL-1R-related proteins and a number of TIR-only proteins (Fig. In the older Reef Genomics dataset for A. digitifera, the corresponding gene for LOC107334364 was Acropora_digitifera_14046l.

Using the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway database14, the metabolic repertoire of Acropora was compared to that of its non-symbiotic relative, the sea anemone Nematostella (Supplementary Table 10), leading to the identification of an apparent metabolic deficiency in Acropora. Under permits from the Aquaculture Agency of Okinawa Prefecture (the number 20–27), part of an A. digitifera colony was collected and has subsequently been maintained in an aquarium at the Sesoko Station, Tropical Biosphere Research Center, University of the Ryukyus. 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. Shinzato, C., Shoguchi, E., Kawashima, T. et al. Discussion about Acropora digitifera v1.0. Despite being classified on the basis of skeletal characteristics into different species groups sensu Wallace and Wolstenholme (1998), molecular data indicate that A. millepora and A. digitifera are close relatives (e.g., van Oppen et al. A number of candidate organic-matrix proteins were identified in Acropora (Supplementary Fig. CAS Article Google Scholar 15. Nature. Despite the ecological and economic significance of corals, the molecular mechanisms underlying much of coral biology—including stress responses and disease—remain unclear, but it is clear that corals retain much of the complex gene repertoire of the ancestral metazoan7.
