Cyprinus carpio 'koi' Raw sequence reads

ABSTRACT: Genome-wide analysis of skin color-related lncRNA and mRNA expression in Koi carp, Cyprinus carpio L. LncRNAs information linked to fish skin color regulation is over-limited. In this study, Illumina sequencing and bioinformatics were primarily conducted on black, white and red skin colors of Koi carp. A total of 590,415,050 clean reads, 446,614 putative transcripts, 4,252 known and 72,907 novel lncRNAs were simultaneously obtained, respectively. Out of these genes, 92 significant differentially expressed lncRNAs and 722 mRNAs were excavated. Ccr_lnc5622441, Ccr_lnc765201 were found up-regulated in black and red skins; Ccr_lnc14074601 were up-regulated in white skin; and premelanosome proteins a (Pmela), tyrosinase (Tyr) were up-regulated in black skin, etc. Quantitative real-time PCR (qRT-PCR) further validated 12 differentially expressed genes were consistent with RNA-seq. Moreover, 70 lncRNAs on 107 target mRNAs in cis and 79 lncRNAs on 41,625 target mRNAs in trans were investigated, the networks revealed one lncRNAs can connected with numerous mRNAs, vice versa. These findings broadened the lncRNAs landscape of skin colors and provided new insights into the mechanisms underlying lncRNAs mediated pigmentation and differentiation in Koi carp.

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.
