Project description: Purpose:In order to elucidate the molecular mechanism of the stripe patterns in B. superciliaris skin.These results will enhance understanding of molecular mechanisms underlying skin pigmentation and facilitate molecular-assisted selection of highly valued skin colors. Methods:In this study, Illumina sequencing was employed to identify the mRNAs and miRNAs involved in stripe pattern formation in B. superciliaris skin. target prediction revealed a variety of putative target genes; differentially expressed mRNAs and miRNAs patterns were observed in 5 mRNAs and mir-217 by qRT-PCR. Results:Based on the zebrafish genome, a total of 44,206,176 and 46,941,318 high-quality transcriptome reads were generated, which resulted in 134,586 unigenes that were used as reference sequences. A total of 24,113 genes exhibited significantly different expression patterns (fold-change ≥ 2 or ≤ 0.5 and q ≤ 0.05), including 15,117 up-regulated genes and 8,996 down-regulated genes associated with black and yellow stripes.These genes were enriched in 65 GO terms and 7 KEGG pathways (q ≤ 0.05), which included melanogenesis, and contained 32 up-regulated genes and 12 down-regulated genes. High-throughput miRNA sequencing identified a total of 355 miRNAs, which included 38 novel miRNAs. Furthermore, 87 differentially expressed miRNAs that contained 50 up-regulated and 37 down-regulated miRNAs were identified in different color skin Conclusions:This study provides novel insight into the mechanism that produces different color stripes in B. superciliaris by combining RNA-seq with small RNA-seq. 5 genes and 1 miRNAs were selected arbitrarily for verification . Compared with previous fish studies, revealed that these DE mRNAs and miRNAs are likely involved in melanin synthesis, and the quantitative mRNA/miRNA data and pathway information presented here provide a strong basis for elucidation of the detailed functions of mRNAs and miRNAs associated with black and yellow stripe formation in aquarium fish.

Project description:The naked mole-rat (NMR; Heterocephalus glaber) has recently gained considerable attention in the scientific community for its unique potential to unveil novel insights in the fields of medicine, biochemistry, and evolution. NMRs exhibit unique adaptations that include protracted fertility, cancer resistance, eusociality, and anoxia. This suite of adaptations is not found in other rodent species, suggesting that interrogating conserved and accelerated regions in the NMR genome will find regions of the NMR genome fundamental to their unique adaptations. However, the current NMR genome assembly has limits that make studying structural variations, heterozygosity, and non-coding adaptations challenging. We present a complete diploid naked-mole rat genome assembly by integrating long-read and 10X-linked read genome sequencing of a male NMR and its parents, and Hi-C sequencing in the NMR hypothalamus (N=2). Reads were identified as maternal, paternal or ambiguous (TrioCanu). We then polished genomes with Flye, Racon and Medaka. Assemblies were then scaffolded using the following tools in order: Scaff10X, Salsa2, 3d-DNA, Minimap2-alignment between assemblies, and the Juicebox Assembly Tools. We then subjected the assemblies to another round of polishing, including short-read polishing with Freebayes. We assembled the NMR mitochondrial genome with mitoVGP. Y chromosome contigs were identified by aligning male and female 10X linked reads to the paternal genome and finding male-biased contigs not present in the maternal genome. Contigs were assembled with publicly available male NMR Fibroblast Hi-C-seq data (SRR820318). Both assemblies have their sex chromosome haplotypes merged so that both assemblies have a high-quality X and Y chromosome. Finally, assemblies were evaluated with Quast, BUSCO, and Merqury, which all reported the base-pair quality and contiguity of both assemblies as high-quality. The assembly will next be annotated by Ensembl using public RNA-seq data from multiple tissues (SRP061363). Together, this assembly will provide a high-quality resource to the NMR and comparative genomics communities.

Project description:Porcine 60K BeadChip genotyping arrays (Illumina) are increasingly being applied in pig genomics to validate SNPs identified by re-sequencing or assembly-versus-assembly method. Here we report that more than 98% SNPs identified from the porcine 60K BeadChip genotyping array (Illumina) were consistent with the SNPs identified from the assembly-based method. This result demonstrates that whole-genome de novo assembly is a reliable approach to deriving accurate maps of SNPs.

Project description:The complete mitochondrial genome of Sinibotia superciliaris was determined in this study. It contained 13 protein-coding genes (PCGs), 22 tRNA, 2 rRNAs, and a control region with the base composition 31.57% A, 27.18% C, 25.52% T, and 15.74% G. Here we compared this newly determined mitogenome with another one from the same species reported before. The variable sites and the genetic distances between the two mitogenomes were 20 bp and 0.1%. 15 variable sites were occurred in the PCGs. The results from the phylogenetic analysis showed that the genus Sinibotia is a monophyletic group and S. superciliaris demonstrate a sister relationship with Sinibotia pulchra.
