In addition, A. fulica is also the intermediate host of the parasitic nematode Angiostrongyl cantonensis. . . Limited levels of lineage sampling, however, may distort such analyses. The distribution of k-mer species estimated for A. fulica. At present, the snail has been found in the wild in Guangdong, Hainan, Guangxi, southern parts of Yunnan Province and Fujian Province, and a county of Guizhou Province [11]. Bioanalyzer summary reports for samples used in the transcriptome sequencing. MicroRNAs (miRNA) are small non-coding RNAs that act post-transcriptionally to regulate gene expression levels. Therefore, we isolated five different α-tubulin clones from a genomic library using a 32P-labeled α-tubulin-2 cDNA probe. Barghi N, Concepcion GP, Olivera BM, et al. The Illumina, PacBio, and Hi-C sequencing data are available from NCBI via the accession numbers SRR8369706, SRR8369311, and SRR8371669, respectively. Maldonado JA, Simoes RO, Oliveira AP, et al. First of all, we compared the sequence number and contig N50 length of A. fulica with publicly available mollusk genomes and found that our assembly has a high quality on contig and scaffold N50 among mollusk genomes (Table 3). 31. 2012) and plays an important role in investigating climate change effects in freshwater ecosystems (Sommer et al. Y.G., Y.Z., Q.L., Z.W. wrote the manuscript. We estimated the genome size at 2.12 Gb with heterozygosity of 0.47% and repeat content of 71% in the genome. Sequencing data generated for A. fulica genome assembly and annotation. According to previous karyotype analyses, A. fulica has 31 chromosomes [34]. Bases in sliding 5-bp windows were deleted if the average quality of the window was below phred quality score of 20. Given the increasing interest in mollusk genomic evolution and the biological importance of A. fulica as an invasive animal, our genomic and transcriptome data will provide valuable genetic resources for follow-on functional genomics investigations by the research community. Moreover, ∼70.37% of the multi-exon FLNCs were really full-length sequences embracing all the exons of the gene locus predicted from the whole-genome sequences. 3). We obtained 1.85 Gb genome with 8,585 contigs, with a contig N50 of 726.63 kb. The authors declare that they have no competing interests. Third, the mate reads were also removed if the corresponding reads were filtered. Guided by the protein multi-sequence alignment, the alignment of the CDSs for those genes was generated and concatenated for the following analysis. It inhabits the coasts of Europe from Norway through Portugal as well as Bermuda.

To functionally annotate protein-coding genes in the A. fulica genome, we searched all predicted gene sequences against the NCBI non-redundant nucleotide (NT) and protein (NR) and Swiss-Prot databases using the BLASTN (BLASTN, RRID:SCR_001598) [60] and BLASTX (BLASTX, RRID:SCR_001653) [61] utilities. “Draft Genome Assemblies and Predicted MicroRNA Complements of the Intertidal Lophotrochozoans Patella Vulgata (Mollusca, Patellogastropoda) and Spirobranchus (Pomatoceros) Lamarcki (Annelida, Serpulida).” Marine Genomics 24 … Dev. As a result, a 1.93-Gb genome was constructed with 10,417 contigs and a contig N50 length of 662.40 kb. In mainland China, the first A. fulica invasion event was reported in 1931 [10]. and N.X. The total number of k-mer species is 178,847,565,204, with the peak value (depth) being 76. Marine Genomics, 24(2), pp. Only proteins from the longest transcript were used for genes with alternative isoforms. FALCON was also employed using the length_cutoff and pr_length_cutoff parameters of 10 and 8 kb, respectively. The high-quality samples are highlighted in red for the PacBio library construction and sequencing. Liver pancreas tissue of A. fulica was used for library construction for Hi-C analysis, and the library was constructed using the identical method as previous studies [31]. Previous studies have revealed that repeat content varies in mollusks and is correlated with genome size [26]. Supplemental Figure S1. For example, the common limpets shown in Figure 6 carry the formal scientific name of Patella vulgata Linnaeus, 1758. Langmead B, Trapnell C, Pop M, et al. We successfully clustered these contigs into 31 groups in Lachesis [35] using the agglomerative hierarchical clustering method (Fig. The large genome size and high proportion of repeat content of A. fulica provided additional supporting data for the statistical analysis. We found an approximate genome size of 1.46 Gbp (25.7 × base pair coverage) in P. vulgata using the estimate_genome_size.pl script , and an estimate of 0.95 Gbp (22 × k-mer coverage, 28.2 × base pair coverage) using the k-mer spectrum approach, with a single peak of k-mer coverage. The data are associated with the publication: Draft genome assemblies and predicted microRNA complements of the intertidal lophotrochozoans Patella vulgata (Mollusca, Patellogastropoda) and Spirobranchus (Pomatoceros) lamarcki (Annelida, Serpulida). Compared with the estimated genome size, the assembled version was relatively smaller, which may have resulted from the following 2 possible scenarios: the high repeat content of the genome and the probably larger size estimated from the k-mer analysis. To our knowledge, the A. fulica genome is the first terrestrial mollusk genome published to date. . Blast2GO (Blast2GO, RRID:SCR_005828) [62] was also used to assign gene ontology (GO) [63] and KEGG [64] pathways. . and N.X.

An adult snail (Fig. Its expression is restricted to the posterior quadrant: it is first seen in 3D, then propagates to the first cells that switch to a bilaterally … The gastropod Patella vulgata is abundant on rocky shores in Northern Europe and a significant grazer of intertidal algae. Sperm and eggs are readily isolated from male and female forms of this species. The resulting de novo data, combined with the known repeat library from Repbase [55], were used to identify TEs in the A. fulica genome by means of RepeatMasker4–0-8 (RepeatMasker, RRID:SCR_012954) [56] software. Moreover, 10,000 pairs of short reads were extracted randomly and were compared to the nt database and no obvious external contamination was found. Protein sequences of closely related species including Aplysia californica, B. glabrata, Crassostrea gigas, Lottia gigantea, and Patinopecten yessoensis were downloaded from the Ensembl database and aligned to the A. fulica genome with TBLASTN2.6.0 (TBLASTN, RRID:SCR_011822). 2016YFC1200500 and 2016YFC1202000). . DNA was extracted using the traditional phenol/chloroform extraction method and was quality checked using agarose gel electrophoresis, meeting the requirement for library construction for the Illumina X Ten (Illumina Inc., San Diego, CA, USA) and for the PacBio Sequel (Pacific Biosciences, Menlo Park, CA, USA) sequencing platforms. Meaning of patella vulgata. Patella vulgata upper side (left) and underside (right).. Traditional chromosomal genome assembly requires physical maps and genetic maps, which is enormously time- and labor-consuming. To ensure the quality of the analysis, ambiguous bases and low-quality reads were trimmed and filtered using the HTQC package (version 1.92.3) [23]. 3 synonyms for patella: kneecap, kneepan, genus Patella. Guindon S, Lethiec F, Duroux P, et al. This snail has been recognized as an agricultural and garden pest causing significant damage in both tropical and subtropical regions [9, 13, 14]. Some studies have indicated that microRNAs may have low homoplasy, and as a consequence the phylogenetic distribution of microRNA families has been used to study animal evolutionary relationships. . Nederbragt, A. J., Loon, A. E. van, & Dictus, W. J. Second, reads were filtered if the average phred quality score was <20 or the read length was <75 bp. Length distribution comparison of genes (A), CDSs (B), exons (C), and introns (D) for A. fulica to those in the closely related mollusk species A. californica, B. glabrata, C. gigas, L. gigantea, P. yessoensis, and O. bimaculoides. Lophotrochozoa is an under-sampled taxon that includes molluscs, annelids and nemerteans, among other phyla. Full-length transcripts obtained using Iso-Seq were mapped to the genome using Genewise (GeneWise, RRID:SCR_015054) [58]. These authors contributed equally to this work. The full formal name also includes the last name of the scientist who described the species and the year in which it was named.
