Comparative transcriptome analysis reveals critical genes/pathways related yolk precursor synthesis in livers of Guangxi Ma chicken with different egg laying rate

Project description:Liver tissues of Guangxi Ma chicken from 32-week old with m performance, 50-week old with high and low laying performance, and 72-week old with high and low laying performance were collected and sequenced in quadruplicate using RNA-seq. The sequences were double-ended sequenced on the DNBSEQ sequencing platform. The sequence reads were quality controlled and then aligned with genomic sequences using HISAT2 program, quantified by featureCounts program, and gene expression levels were verified by qRT-PCR with SYBR Green detection. The results will be helpful to explore the factors that affecting laying performance from the perspective of yolk synthesis and provide a theoretical basis for improving the egg production of Guangxi Ma chicken.

Genomic Analysis Reveals Pleiotropic Alleles at EDN3 and BMP7 Involved in Chicken Comb Color and Egg Production

Project description:Dongxiang blue-shelled chicken, an indigenous chicken breed in China, has segregated significantly for the dermal hyperpigmentation phenotype. Two lines of the chicken have been divergently selected with respect to comb color for over 20 generations. The recent selection has also resulted in a significant difference in egg production. The red comb line (RCL) chicken produces significantly higher number of eggs than that by the dark comb line (DCL) chicken. The objective of this study was to explore potential mechanisms involved in the relationship between comb color and egg production among chickens. We performed genome-wide association study to identify candidate genes associated with chicken comb color using SNP array data, and we conducted selective sweep analysis to identify putative regions of selection harboring pleiotropic genes affecting both comb color and egg production.

Gene expression data of two different strains of laying hens from a small group housing system

Project description:Comparative analysis of gene expression profiles in newly developed housing systems is important to understand gene functions in chicken for adaptation and possible gene-environment interactions among layer lines. Therefore, the objective of this study was to characterize the molecular processes that are different among the two layer lines Lohmann Selected Leghorn (LSL) and Lohmann Brown (LB) using whole genome RNA expression profiles. Despite their approximately identical egg production performance these layer lines differ markedly in other phenotypic traits. The two layer lines were kept under the production environment of the newly developed small group housing system Eurovent German with two different group sizes and three tiers. We used a chicken RNA microarray to identify differentially expressed genes among the two layer lines LSL and LB.

Morphological and transcriptomic effects of endocrine modulators on the gonadal differentiation of chicken embryos: the case of tributyltin (TBT)

Project description:Chicken eggs (Gallus gallus domesticus) were incubated, after 24 h of incubation either non-injected (control, C), or injected with the solvent sesame oil (Oleum Sesame Raffinatum, solvent control, SC), and the substances Tributyltin (TBT, 10pg TBT-SN/g egg) or 17alpha-Methyltestosteron (MT, 30 pg/g egg). Animals were decapitated on breeding day 19, 2 days before anticipated hatching. Right and left gonads of female and male chicken were accurately separated from adhesing tissues, stored in RNA lysis buffer (Promega) at -80°C until until RNA isolation with the SV Total RNA Isolation System Kit according to manual 048 (Promega). Sequencing was performed on Illumina’s Genome Analyzer IIx, and subsequent base calling was carried out by Illumina’s GAPipeline. Our study represents the first detailed analysis of whole chicken gonad transcriptomes, with biologic replicates, generated by SuperSAGE technology.

The dynamic methylome of the broiler chicken as a resource for livestock performance biomarker development

Project description:The broiler chicken is the globally most important source of commercially produced meat. While genetic approaches have played an important role in the development of chicken stocks, little is known about chicken epigenetics. We have now systematically analyzed the chicken DNA methylation toolkit and DNA methylation landscape. While overall DNA methylation patterns were similar to mammals, sperm DNA appeared distinctly hypomethylated, which correlates with the absence of the DNMT3L cofactor in the chicken genome. Additional analysis also revealed the presence of low-methylated regions in the chicken methylome, which are conserved gene regulatory elements that show tissue-specific methylation patterns. We also used whole-genome bisulfite sequencing to establish 56 single-base resolution methylomes of the broiler chicken from various tissues and developmental time points. Data analysis confirmed tissue-specific and time-dependent methylation patterns that were used to establish a DNA methylation clock to predict sample age and measure stock performance. Our study thus provides a comprehensive resource for the chicken methylome and establishes a novel epigenetic tool for livestock performance analysis.

Transcriptome-wide m6A methylation of Wuhua yellow-feathered chicken ovary revealed potential molecular mechanisms underlying the low egg performance

Project description:RNA N6-melthyladenosine has been suggested to play important roles in various biological processes. Chicken ovary development is a process controlled by complex gene regulations. In this study, transcriptome-wide m6A methylation of the Wuhua yellow-feathered chicken ovaries before and after sexual maturation was profiled to identify potential molecular mechanisms underlying chicken ovary development. The results showed that m6A levels of mRNAs changed dramatically during sexual maturity. A total of 1476 differential m6A peaks were found between these two stages with 662 significantly up-regulated methylation peaks and 814 down-regulated methylation peaks after sexual maturation. A positive correlation was found between the m6A peaks and gene expression levels. Functional enrichment analysis indicated that apoptosis related pathways might be the key molecular regulatory pathway underlying the poor reproductive performance of Wuhua yellow-feathered chicken. The fine expressional regulation of genes related to follicles development and follicle atresia controlled by m6A during the maturity results in the poor reproductive performance in the Wuhua yellow-feathered chicken. However, the regulatory mechanisms are still unclear, thus more further studies are required. The pathways and corresponding candidate genes found here may be useful for molecular design breeding for improving egg production performance in Chinese local chicken breed, and it will also benefit for the genetic resource protection of valuable avian species.

Egg-coat degradation

Project description:Vertebrate oocytes are coated with a special extracellular matrix termed egg-coat or Zona pellucida (ZP). Egg-coat is constituted by several ZP glycoproteins. In chicken fertilization, ejaculated sperm releases enzyme(s) to solubilize the ZP glycoprotein(s) for penetrating the egg-coat. In this study, we analyzed the solubilized ZP glycoprotein fragment. We also analyzed the glycosylation property of its fragment.
