Project description:We report the genome-wide DNA methylation mapping of chicken by methylated DNA immunoprecipitation following by highthroughput sequencing, and the gene expression profile of chicken by RNA-seq. For meDIP-seq, about 17,202,074 to 27,501,760 reads were generated for the tissue and liver tissues of the red jungle fowl and the avian broiler each. We found that compared with the red jungle fowl, DNA methylation in muscle tissue of the avian broiler, showed dramatically decline on a genome-wide scale. Furthermore, the length of the highly methylated regions (HMRs) has become shorter in the avian broiler, which has suffered intense artificial selection. In addition to the global changes in DNA methylation, transcriptome-wide analysis of the two breeds of chicken revealed that the patterns of gene expression in the domestic chicken have undergone a specific bias towards a pattern that is more suited to human-made environments with variable expression in certain gene functions, such as immune response and fatty acid metabolism. Our results demonstrated a potential role of epigenetic modification in animal domestication besides the genetic variations. Examination of whole genome DNA methylation status in liver and muscle of two chicken breeds.

Identification of copy number variation using aCGH in Chinese chicken breeds

Project description:CNV plays an important role in the chicken genomic studies,it is imperative need to investigate the extent and pattern of CNVs using array comparative genomic hybridization (aCGH) in chinese chicken breeds for future studies associating phenotype to genome architecture. we describe systematic and genome-wide analysis of CNVs loci in five Chinese indigenous chicken breeds were evaluated by aCGH.

Dehong chicken blood samples vs. 22 different chicken blood samples belonging to 11 breeds

Project description:Copy number variation profiles comparing control female Dehong chiken blood DNA with 11 different chicken breeds(Silkie, Tibetan Chicken, Gallus gallus spadiceus, Bearded Chicken, Jinhu Chicken, Anak Chicken, Beijing Fatty Chicken, Langshan Chicken, Qingyuan partridge Chicken, Shek-Ki Chicken, Wenchang Chicken) blood DNA. Each test breeds had one male and one female sample, totally 22 test DNA samples.Goal is to get the golbal copy number variation profile between chicken breeds.
