Dehong chicken blood samples: Control vs. 6 chicken blood samples belonging to 3 different breeds

ABSTRACT: Copy number variation profiles comparing control female Dehong chicken blood DNA with 3 different chicken breeds (white Leghorn, Cobb broiler, and Dou chicken) blood DNA. Each test breed had one male and one female sample, for a total of 6 test DNA samples. The goal is to determine the global copy number variation profiles between chicken breeds. Female Dehong chicken DNA as reference DNA vs. 6 test chicken DNA samples.

The discovery of copy number variation (CNV) in the genome has provided new insight into genomic polymorphism. Studies with chickens have identified a number of large CNV segments using a 385k comparative genomic hybridization (CGH) chip (mean length >140 kb). We present a detailed CNV map for local Chinese chicken breeds and commercial chicken lines using an Agilent 400k array CGH platform with custom-designed probes. We identified a total of 130 copy number variation regions (CNVRs; mean lengt ...[more]

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. 5 Chinese native chicken were detected using ANKA broiler as reference.

Comparative genomic hybridization of chicken and Japanese quail

Project description:Since Japanese quail and chicken belong to the same order Galliforms, DNA sequence of both species are highly conserved and proved to be applicable for various analyses each other. Quail are commonly used to address physiological questions for reasons of economy. To test whether chicken microarrays are useful to quail samples, we compared hybridization signals of chicken and quail genomic DNA on Affymetrix chicken genome array. Experiment Overall Design: Genomic DNA of female chicken and quail were extracted individually from liver of three birds and hybridized on Affymetrix microarrays. Samples were analyzed in triplicate set of array (three biological replicates).

Transcription profiling of chicken embryonic hears from Tibetan Chicken, Dwarf Recessive White Chicken and Shouguang Chicken

Project description:Adaptation to hypoxia is a complicated and important physiological course for organisms, but the genetic mechanism underlying the adaptation is not fully understood yet. Tibetan Chicken (T), an indigenous chicken breed in China which inhabit in high areas with an altitude above 2,900 meters. Shouguang Chicken(S) and Dwarf Recessive White Chicken (DRW), two lowland chicken breeds, were used as control groups. The heart was the first functional organ to develop during the embryonic development. Furthermore, the heart is an efficient energy converter utilizing the most appropriate fuel for a given environment. Therefore, GeneChipÂ® Chicken Genome Array was employed to identify the differentially expressed genes in embryonic hearts of Tibetan Chicken and two lowland chicken breeds in both hypoxic and normoxic incubating environments with a genome wide profile. Experiment Overall Design: To obtain general expression profiles of embryonic hearts in Tibetan Chicken(T), Dwarf Recessive White Chicken (DRW)and Shouguang Chicken (S)in hypoxia and normoxia, the fertilized full sib eggs of all the three chicken breeds were incubated under two different conditions. The heart was isolated from all the three chicken breeds under the two different conditions for RNA extraction and hybridization on Affymetrix microarrays.

Affymetrix SNP array data for chicken samples

Project description:The conservation and development of chicken has considerably affected human activities, but the admixture history of chicken breeds has so far been poorly demonstrated especially for Chinese indigenous breeds. Using genotypes from 580961 single nucleotide polymorphism markers scored in 1201 animals, we evaluate the genetic diversity (heterozygosity and proportion of polymorphic markers), Linkage disequilibrium (LD) decay, population structure (principal component analysis and neighbor-joining tree), genetic differentiation (FST and genetic distance) and migration events (Treemix and f-statistics) of eight domesticated chicken breeds. All population analytical methods reveal patterns of hybridization which occurred after divergence in Tibetan chicken. We argue that chicken migration and admixture followed by trade have been important forces in shaping modern Chinese chicken genomic variation. Moreover, isolation by distance may play critical role in the shaping genomic variation within Eurasia continent chicken breeds.
