  • Transposon-associated epigenetic silencing during Pleurotus ostreatus life
           cycle

    • Authors: Borgognone A; Castanera R, Morselli M, et al.
      Pages: 451 - 464
      Abstract: Transposable elements constitute an important fraction of eukaryotic genomes. Given their mutagenic potential, host-genomes have evolved epigenetic defense mechanisms to limit their expansion. In fungi, epigenetic modifications have been widely studied in ascomycetes, although we lack a global picture of the epigenetic landscape in basidiomycetes. In this study, we analysed the genome-wide epigenetic and transcriptional patterns of the white-rot basidiomycete Pleurotus ostreatus throughout its life cycle. Our results performed by using high-throughput sequencing analyses revealed that strain-specific DNA methylation profiles are primarily involved in the repression of transposon activity and suggest that 21 nt small RNAs play a key role in transposon silencing. Furthermore, we provide evidence that transposon-associated DNA methylation, but not sRNA production, is directly involved in the silencing of genes surrounded by transposons. Remarkably, we found that nucleus-specific methylation levels varied in dikaryotic strains sharing identical genetic complement but different subculture conditions. Finally, we identified key genes activated in the fruiting process through the comparative analysis of transcriptomes. This study provides an integrated picture of epigenetic defense mechanisms leading to the transcriptional silencing of transposons and surrounding genes in basidiomycetes. Moreover, our findings suggest that transcriptional but not methylation reprogramming triggers fruitbody development in P. ostreatus.

  • Transcriptomic and functional analyses unveil the role of long non-coding
           RNAs in anthocyanin biosynthesis during sea buckthorn fruit ripening

    • Authors: Zhang G; Chen D, Zhang T, et al.
      Pages: 465 - 476
      Abstract: Fruit ripening is a developmental process regulated by a complex network of endogenous and exogenous cues. Sea buckthorn is an excellent material for fruit ripening studies due to its dramatic ripening process and high contents of nutritional and anti-oxidant compounds in berries. Here, the whole transcriptome of sea buckthorn fruit at three development stages were analysed using multiple high-throughput sequencings. We assembled and annotated 9,008 long non-coding RNAs (lncRNAs) in sea buckthorn fruits, and identified 118 differentially expressed lncRNAs (DE-lncRNAs) and 32 differentially expressed microRNAs in fruit developmental process. In addition, we predicted 1,061 cis-regulated and 782 trans-regulated targets of DE-lncRNAs, and these DE-lncRNAs are specifically enriched in the biosynthesis of ascorbic acid, carotenoids and flavonoids. Moreover, the silencing of two lncRNAs (LNC1 and LNC2) in vivo and expression analysis revealed that LNC1 and LNC2 can act as endogenous target mimics of miR156a and miR828a to reduce SPL9 and induce MYB114 expression, respectively, which lead to increased and decreased anthocyanin content as revealed by high-performance liquid chromatography analysis. Our results present the first global functional analysis of lncRNA in sea buckthorn and provide two essential regulators of anthocyanin biosynthesis, which provides new insights into the regulation of fruit quality.

  • Optimization of single strand DNA incorporation reaction by Moloney murine
           leukaemia virus reverse transcriptase

    • Authors: Ohtsubo Y; Sasaki H, Nagata Y, et al.
      Pages: 477 - 487
      Abstract: In this study, we investigated CIS reaction (clamping-mediated incorporation of single-stranded DNA with concomitant DNA syntheses) of Moloney murine leukaemia virus reverse transcriptase (MMLV-RT), and established a set of conditions with which single-stranded DNA is ligated to a G-tailed model substrate DNA at efficiencies close to 100%. Prior to the CIS reaction, a target blunt-end DNA was 3′ G-tailed by MMLV-RT in the presence of a tailing enhancer, deoxycytidine. In the CIS reaction, the G-tail reacted with a single-stranded DNA carrying a stretch of Cs on its 3′ end (termed as GAO for guide adaptor oligonucleotide), and MMLV-RT performed DNA polymerization, starting from the 3′ overhang, using the GAO as a template. We could append a given nucleotide sequence of as long as 72 nucleotides, which would be sufficient for various NGS-sequencing platforms. The high efficiency and the unique features of this MMLV-RT activity that enables the labelling of each DNA molecule with a unique degenerate sequence as a molecular identifier has many potential uses in biotechnology.

  • The GntR family transcriptional regulator PMM1637 regulates the highly
           conserved cyanobacterial sRNA Yfr2 in marine picocyanobacteria

    • Authors: Lambrecht S; Wahlig J, Steglich C, et al.
      Pages: 489 - 497
      Abstract: Prochlorococcus is a marine picocyanobacterium with a streamlined genome that is adapted to different ecological niches in the oligotrophic oceans. There are currently >20 regulatory small RNAs (sRNAs) that have been identified in the model strain Prochlorococcus MED4. While most of these sRNAs are ecotype-specific, sRNA homologs of Yfr1 and of the Yfr2 family are widely found throughout the cyanobacterial phylum. Although they were identified 13 yrs ago, the functions of Yfr1 and Yfr2 have remained unknown. We observed a strong induction of two Yfr2 sRNA homologs of Prochlorococcus MED4 during high light stress and nitrogen starvation. Several Prochlorococcus and marine Synechococcus yfr2 promoter regions contain a conserved motif we named CGRE1 (cyanobacterial GntR family transcriptional regulator responsive element 1). Using the conserved promoter region as bait in a DNA affinity pull-down assay we identified the GntR family transcriptional regulator PMM1637 as a binding partner. Similar to Yfr2, homologs of PMM1637 are universally and exclusively found in cyanobacteria. We suggest that PMM1637 governs the induction of gene expression of Yfr2 homologs containing CGRE1 in their promoters under nitrogen-depleted and high-light stress conditions.

  • The genome of tapeworm Taenia multiceps sheds light on understanding
           parasitic mechanism and control of coenurosis disease

    • Authors: Li W; Liu B, Yang Y, et al.
      Pages: 499 - 510
      Abstract: Coenurosis, caused by the larval coenurus of the tapeworm Taenia multiceps, is a fatal central nervous system disease in both sheep and humans. Though treatment and prevention options are available, the control of coenurosis still faces presents great challenges. Here, we present a high-quality genome sequence of T. multiceps in which 240 Mb (96%) of the genome has been successfully assembled using Pacbio single-molecule real-time (SMRT) and Hi-C data with a N50 length of 44.8 Mb. In total, 49.5 Mb (20.6%) repeat sequences and 13, 013 gene models were identified. We found that Taenia spp. have an expansion of transposable elements and recent small-scale gene duplications following the divergence of Taenia from Echinococcus, but not in Echinococcus genomes, and the genes underlying environmental adaptability and dosage effect tend to be over-retained in the T. multiceps genome. Moreover, we identified several genes encoding proteins involved in proglottid formation and interactions with the host central nervous system, which may contribute to the adaption of T. multiceps to its parasitic life style. Our study not only provides insights into the biology and evolution of T. multiceps, but also identifies a set of species-specific gene targets for developing novel treatment and control tools for coenurosis.

  • Genome-wide characterization of DNA methylation, small RNA expression, and
           histone H3 lysine nine di-methylation in Brassica rapa L.

    • Authors: Takahashi S; Osabe K, Fukushima N, et al.
      Pages: 511 - 520
      Abstract: Epigenetic gene regulation is crucial to plant life and can involve dynamic interactions between various histone modifications, DNA methylation, and small RNAs. Detailed analysis of epigenome information is anticipated to reveal how the DNA sequence of the genome is translated into the plant’s phenotype. The aim of this study was to map the DNA methylation state at the whole genome level and to clarify the relationship between DNA methylation and transcription, small RNA expression, and histone H3 lysine 9 di-methylation (H3K9me2) in Brassica rapa. We performed whole genome bisulfite sequencing, small RNA sequencing, and chromatin immunoprecipitation sequencing using H3K9me2 antibody in a Chinese cabbage inbred line, RJKB-T24, and examined the impact of epigenetic states on transcription. Cytosine methylation in DNA was analysed in different sequence contexts (CG, CHG, and CHH) (where H could be A, C, or T) and position (promoter, exon, intron, terminator, interspersed repeat regions), and the H3K9me2 and 24 nucleotide small interfering RNAs (24 nt-siRNA) were overlaid onto the B. rapa reference genome. The epigenome was compared with that of Arabidopsis thaliana and the relationship between the position of DNA methylation and gene expression, and the involvement of 24 nt siRNAs and H3K9me2 are discussed.

  • Mobile elements contribute to the uniqueness of human genome with 15,000
           human-specific insertions and 14 Mbp sequence increase

    • Authors: Tang W; Mun S, Joshi A, et al.
      Pages: 521 - 533
      Abstract: Mobile elements (MEs) collectively contribute to at least 50% of the human genome. Due to their past incremental accumulation and ongoing DNA transposition, MEs serve as a significant source for both inter- and intra-species genetic and phenotypic diversity during primate and human evolution. By making use of the most recent genome sequences for human and many other closely related primates and robust multi-way comparative genomic approach, we identified a total of 14,870 human-specific MEs (HS-MEs) with more than 8,000 being newly identified. Collectively, these HS-MEs contribute to a total of 14.2 Mbp net genome sequence increase. Several new observations were made based on these HS-MEs, including the finding of Y chromosome as a strikingly hot target for HS-MEs and a strong mutual preference for SINE-R/VNTR/Alu (SVAs). Furthermore, ∼8,000 of these HS-MEs were found to locate in the vicinity of ∼4,900 genes, and collectively they contribute to ∼84 kb sequences in the human reference transcriptome in association with over 300 genes, including protein-coding sequences for 40 genes. In conclusion, our results demonstrate that MEs made a significant contribution to the evolution of human genome by participating in gene function in a human-specific fashion.

  • Design and evaluation of a sequence capture system for genome-wide SNP
           genotyping in highly heterozygous plant genomes: a case study with a
           keystone Neotropical hardwood tree genome

    • Authors: Silva-Junior O; Grattapaglia D, Novaes E, et al.
      Pages: 535 - 545
      Abstract: Targeted sequence capture coupled to high-throughput sequencing has become a powerful method for the study of genome-wide sequence variation. Following our recent development of a genome assembly for the Pink Ipê tree (Handroanthus impetiginosus), a widely distributed Neotropical timber species, we now report the development of a set of 24,751 capture probes for single-nucleotide polymorphisms (SNPs) characterization and genotyping across 18,216 distinct loci, sampling more than 10 Mbp of the species genome. This system identifies nearly 200,000 SNPs located inside or in close proximity to almost 14,000 annotated protein-coding genes, generating quality genotypic data in populations spanning wide geographic distances across the species native range. To provide recommendations for future developments of similar systems for highly heterozygous plant genomes we investigated issues such as probe design, sequencing coverage and bioinformatics, including the evaluation of the capture efficiency and a reassessment of the technical reproducibility of the assay for SNPs recall and genotyping precision. Our results highlight the value of a detailed probe screening on a preliminary genome assembly to produce reliable data for downstream genetic studies. This work should inspire and assist the development of similar genomic resources for other orphan crops and forest trees with highly heterozygous genomes.

  • The yellowtail (Seriola quinqueradiata) genome and transcriptome atlas of
           the digestive tract

    • Authors: Yasuike M; Iwasaki Y, Nishiki I, et al.
      Pages: 547 - 560
      Abstract: Seriola quinqueradiata (yellowtail) is the most widely farmed and economically important fish in aquaculture in Japan. In this study, we used the genome of haploid yellowtail fish larvae for de novo assembly of whole-genome sequences, and built a high-quality draft genome for the yellowtail. The total length of the assembled sequences was 627.3 Mb, consisting of 1,394 scaffold sequences (>2 kb) with an N50 length of 1.43 Mb. A total of 27,693 protein-coding genes were predicted for the draft genome, and among these, 25,832 predicted genes (93.3%) were functionally annotated. Given our lack of knowledge of the yellowtail digestive system, and using the annotated draft genome as a reference, we conducted an RNA-Seq analysis of its three digestive organs (stomach, intestine and rectum). The RNA-Seq results highlighted the importance of certain genes in encoding proteolytic enzymes necessary for digestion and absorption in the yellowtail gastrointestinal tract, and this finding will accelerate development of formulated feeds for this species. Since this study offers comprehensive annotation of predicted protein-coding genes, it has potential broad application to our understanding of yellowtail biology and aquaculture.
