Project description:The genetic foundation of chicken tail feather color is not very well studied to date, though that of body feather color is extensively explored. In the present study, we used a synthetic chicken dwarf line (DW), which was originated from the hybrids between a black tail chicken breed, Rhode Island Red (RIR) and a white tail breed, Dwarf Layer (DL), to understand the genetic rules of the white/black tail color. The DW line still contain the individuals with black or white tails, even if the body feather are predominantly red, after more than ten generation of self-crossing and being selected for the body feather color. We firstly performed four crosses using the DW line chickens including black tail male to female, reciprocal crosses between the black and white, and white male to female to elucidate the inheritance pattern of the white/black tail. We found that (i) the white/black tail feather colors are independent of body feather color and (ii) the phenotype are autosomal simple trait and (iii) the white are dominant to the black in the DW lines. Furtherly, we performed a genome-wide association (GWA) analysis to determine the candidate genomic regions underlying the tail feather color by using black tail chickens from the RIR and DW chickens and white individuals from DW lines.

Project description:This work was to study the transcriptome profiles in the skin of chickens with black versus white skin using high-throughput RNA deep-sequencing technology, to investigate the different expression profiles of the genes involved in skin pigmentation, then look for the main differences between black and white skin colors in Lueyang chickens. 16-week-old white and black female Lueyang chickens (5 birds per color) were selected for the sample collection. A piece of skin (8 mm in diameter) from the left back was collected . Total RNA was extracted from the sample using Trizol reagent . Three RNA samples from either the black or white skin samples were pooled following mRNA isolation. The sequencing of the library was performed using an Illumina HiSeq 2000 (LianChuan Sciences, Hangzhou, China). According the result of sequencing, some colored gene expressions were validated using Real time quantitative polymerase chain reaction (qPCR).

Project description:Transcriptional profiling of the jejunum mucosa with 1.5 fold-change reporter genes in comparing control black-boned chickens under normal temperature (NT) conditon with heat-stress treated black-boned chickens under high temperature (HT) condition. Goal was to determine the differentially expressed genes (DEGs) in co-family black-boned chickens exposure to heat stress based on global chicken gene expression.

Project description:The Yeonsan Ogye (Ogye) is the rare black chicken breed domesticated in Korean peninsula, which has been noted for entire black color upon its appearances including feather, skin, comb, eyes, shank, claws and internal organs. In this study, whole genome, transcriptome and epigenome sequencings of Ogye were performed using high-throughput NGS sequencing platforms. We have produced Illumina short-reads (Paired-End, Mate-Pair and FOSMID) and PacBio long-reads for whole genome sequencing (WGS), 1.4 billion reads for RNA-seq, and 123 million reads for RRBS (reduced representation bisulfite sequencing) data. Using WGS data, Ogye genome has been assembled, and coding/non-coding transcriptome maps were constructed on Ogye genome given largescale sequencing data. We have predicted 17,472 (3,550 newly annotated and 13,922 known) protein-coding transcripts, and 9,443 (6,689 novel and 2,754 known) long non-coding RNAs (lncRNAs).

Project description:Here, we report on a novel chicken comb phenotype, designated Antler-comb. Using a 600K Axiom® Genome-Wide Chicken Genotyping Array, we separately genotyped 12 and 24 female Hetian Wildtype-comb and Antler-comb chickens, respectively. Meanwhile, we sequenced the genomes of 10 Hetian Antler-comb and 10 Wildtype-comb chickens to interrogate the GWAS results and explore the potential genetic variants underlying this phenotype. After conducting a genome-wide association study (GWAS), a 36.5-kb candidate genomic region (chromosome 19:757,754-794,200) related to the Antler-comb phenotype was identified, which wholly and partially encompassed heat shock factor 5 (HSF5) and ring finger protein 43 (RNF43), respectively. HSF5 was ectopically expressed and RNF43 was up-regulated in Antler-comb chickens at embryo ages 7 and 9 (E7 and E9). We further genotyped the most significant single-nucleotide polymorphism (SNP) site, Chr19:794200, across 222 chickens of 16 breeds. We found that the major allele G in Antler-comb chickens remained highly significant across different breeds, and each Antler-comb chicken harbored an allele G. Whole-genome re-sequencing (WGS) involving 10 Hetian Antler-comb and 10 Wildtype-comb chickens reaffirmed the 36.5-kb candidate genomic region, and revealed a genomic duplication, which was 15.7 kb in length and pertained to the 5’-untranslated region and 5’-flanking region of HSF5 (Chr19:784,335-800,034), suggesting its possible role in inducing ectopic expression of HSF5 and altering expression of RNF43 during comb development (E7 and E9). The present study furthers our understanding of this novel chicken comb phenotype, and likely gives another example regarding interactions between genetic variation and phenotype.
