Project description:Background: Intramuscular fat (IMF) content is an important index for beef quality. However, the genetics of IMF deposition is complex and still largely unclear, especially in buffalo. To identify miRNAs with potential regulatory role in lipid accumulated in muscle, we performed small RNA sequencing and identified miRNAs expressed in the longissimus dorsi muscle and back fat of Chinese buffalo, which provided vital information for further identification of miRNAs with potential regulatory role in the lipid accumulated in muscle. Results: Six small RNA libraries were constructed. A total of 66,128,645 and 70,974,347 raw reads were obtained from muscle and adipose groups, respectively. After filtering the adaptor and low quality reads, 60,765,257 and 67,327,095 clean reads were retained. In total, 721 miRNAs were identified.

To identify miRNAs with potential regulatory role in lipid accumulated in muscle, we performed small RNA sequencing and identified miRNAs expressed in the longissimus dorsi muscle and back fat of Chinese buffalo, which provided vital information for further identification of miRNAs with potential regulatory role in the lipid accumulated in muscle. Results: Three small RNA libraries were constructed. A total of 32762032 raw reads were obtained from adipose groups, respectively. After filtering the adaptor and low quality reads, 32054381 clean reads were retained. In total, 623 miRNAs were identified.

Project description:Long non-coding RNAs (lncRNAs) have been identified in various tissues and cell types from human, monkey, porcine and mouse. However, expression profile of lncRNAs across Guangxi native cattle and swamp buffalo muscle development has never been investigated. Here, we examine the expression of lncRNA in cattle and buffalo muscle at adult stage(12 months), exhibiting the first report of lncRNA in the Guangxi native cattle and swamp buffalo muscle development of a large animal. 16,236 lncRNA candidates were obtained from buffalo skeletal muscle samples, of which a number of lncRNAs were highly abundant, and 2,161 lncRNAs were differentially expressed between buffalo and cattle. Real-time quantitative PCR (qPCR) analysis confirmed the expression profile of these lncRNAs, including several highly abundant lncRNAs, and a subset of differently expressed lncRNAs according to the high-throughput RNA sequencing (RNA-seq) data. These results indicate that abundant lncRNA is differentially expressed in bovine muscle, indicating important and diverse functions in mammalian muscle development.

Project description:Background: Intramuscular fat (IMF) content is highly valued as it improves meat product quality by enhancing taste, juiciness, and tenderness. IMF content can be significantly different between breeds. Thought many lipid metabolism-related genes are stated to be associated with IMF deposition, the molecular mechanism of IMF deposition is still poorly understood. To date, no gene or mutation loci responsible for the difference of IMF content among cattle breeds has been identified. To identify transcripts with potential regulatory role in lipid accumulated in muscle tissue, RNA sequencing was performed to compare the mRNAs, lncRNAs, and circRNAs expression patterns in the longissimus dorsi muscle and back fat between Chinese buffalo and cattle. Results: A total of 12 cDNA libraries were constructed. A total of 925,441,106 and 512,507,068 raw reads were obtained from buffalo and cattle, respectively. After filtering the adaptor and low quality reads, 909,040,352 and 491,967,820 clean reads were retained. In total, 19,917 mRNAs, 43,975 lncRNAs, and 10,701 circRNAs were identified in buffalo and 19,383 mRNAs, 8,265 lncRNAs, and 18,535 circRNAs were identified in cattle.

Project description:The swamp eel or rice field eel (Monopterus albus) taxonomically belongs to the family Synbranchidae of the order Synbranchiformes (Neoteleostei, Teleostei, Vertebrata). It is not only an economically important freshwater fish in aquacultural production, but also an increasingly known model species for biological studies. Understanding molecular mechanisms underlying sex change is a major area of interest. The swamp eel thus offers a powerful system for studying sexual development and adaptive evolution in vertebrates.The whole genome sequencing provides valuable resources for sex control in fish production, species protection through manipulating sex reversal genes, and potentially enabling effective population control and promoting reproduction health in human. High throughput sequencing was employed for three samples,three kind s of sex gonad from swamp eel, testis,ovotestis and ovary, no replicates.

Project description:To further probe into whether swamp buffaloes were domesticated once or multiple times in China, this survey examined the mitochondrial DNA (mtDNA) Control Region (D-loop) diversity of 471 individuals representing 22 populations of 455 Chinese swamp buffaloes and 16 river buffaloes. Phylogenetic analysis revealed that Chinese swamp buffaloes could be divided into two distinct lineages, A and B, which were defined previously. Of the two lineages, lineage A was predominant across all populations. For predominant lineage A, Southwestern buffalo populations possess the highest genetic diversity among the three hypothesized domestication centers (Southeastern, Central, and Southwestern China), suggesting Southwestern China as the most likely location for the domestication of lineage A. However, a complex pattern of diversity is detected for the lineage B, preventing the unambiguous pinpointing of the exact place of domestication center and suggesting the presence of a long-term, strong gene flow among swamp buffalo populations caused by extensive migrations of buffaloes and frequent human movements along the Yangtze River throughout history. Our current study suggests that Southwestern China is the most likely domestication center for lineage A, and may have been a primary center of swamp buffalo domestication. More archaeological and genetic evidence is needed to show the process of domestication.

Project description:Buffalo breeding has become an important branch of beef cattle industry. It is of great significance to study buffalo meat production and meat quality. However, the important role of mRNA and lncRNA molecules in muscle stem cells (MuSCs) development in buffalo has not been explored. Then, we performed mRNA and lncRNA expression profiling analysis on the proliferation and differentiation of MuSCs in buffalo. The results showed that there were 4,820 differentially genes, 12,227 mRNAs, and 1,352 lncRNAs. These differentially expressed mRNAs are enriched in biological processes such as cell cycle, p53 signaling pathway, RNA transport, and Calcium signaling pathway and others. We also identified a number of genes, such as MCMC4, SERDINE1, ISLR, LOC102394806, and LOC102403551, and found that interference with MYLPF expression significantly inhibited the differentiation of MuSCs. In conclusion, our research revealed the role of mRNA and lncRNA expression in the differentiation of buffalo MuSCs. This study can be used as an important reference for the study of RNA regulation during muscle development in buffalo.
