Project description:Deep sequencing of mRNA from the rock pigeon Analysis of ploy(A)+ RNA of different specimens: heart and liver from the rock pigeon (Danish Tumbler, Oriental Frill and Racing)
Project description:A comparative profile of miRNAs in livers during pigeon development was performed by using high-throughput sequencing. We identified known pigeon miRNAs, novel miRNAs, and miRNAs that are conserved in other birds and mammals.Our results expanded the repertoire of pigeon miRNAs and may be of help in better understanding the mechanism of squab’s rapid development from the perspective of liver development.
Project description:A comparative profile of miRNAs in pectoral muscle during pigeon development was performed by using high-throughput sequencing. We identified known pigeon miRNAs, novel miRNAs, and miRNAs that are conserved in other birds and mammals.Our results expanded the repertoire of pigeon miRNAs and may be of help in better understanding the mechanism of squab’s rapid development.
Project description:ObjectiveNavigation is the most important feature of homing pigeons, however no integrated response to genetic mechanism of navigation has been reported. The generated data herein represent whole-genome resequencing data for homing pigeon and three other breeds of rock pigeons. Selective sweep analysis between homing pigeon and other breeds of rock pigeon can provide new insight about identification of candidate genes and biological pathways for homing pigeon ability.Data descriptionWhole-genomes sequence data related to 95 birds from four breeds of rock pigeons including, 29 feral pigeons, 24 Shiraz tumblers, 24 Persian high flyers and 18 homing pigeons were provided. More than 6.94 billion short reads with coverage (average ≈7.50 x) and 407.1 Gb data were produced. Whole genome sequencing was carried out on the Illumina Hiseq 2000 platform using a 350 bp library size and 150 bp paired-end read lengths. The whole genome sequencing data have been submitted at the NCBI SRA Database (PRJNA532675). The presented data set can provide useful genomic information to explain the genetic mechanism of navigation ability of homing pigeons and also testing other genetic hypothesis by genomic analysis.
Project description:A comparative profile of miRNAs in pre- and post-differentiated pigeon SMSCs (SMSC-1d and SMSC-5d) was performed by using high-throughput sequencing. We identified known porcine miRNAs, novel miRNAs, and miRNAs that are conserved in other birds and mammals. Our findings demonstrated that miRNAs are extensively involved in the differentiation of SMSCs in pigeons, and provide a valuable resource for the pigeon breeding.
Project description:The domestic rock pigeon (Columba livia) is among the most widely distributed and phenotypically diverse avian species. C. livia is broadly studied in ecology, genetics, physiology, behavior, and evolutionary biology, and has recently emerged as a model for understanding the molecular basis of anatomical diversity, the magnetic sense, and other key aspects of avian biology. Here we report an update to the C. livia genome reference assembly and gene annotation dataset. Greatly increased scaffold lengths in the updated reference assembly, along with an updated annotation set, provide improved tools for evolutionary and functional genetic studies of the pigeon, and for comparative avian genomics in general.
Project description:Hence, in order to investigate the gene expression profiles of skeletal muscle, we analyzed the four stages (1 day, 14 days, 28 days, and 2 years old) of breast muscle in White-King pigeon using transcriptome sequencing.
Project description:We identified 13,072 mRNAs and 19,129 lncRNAs, of which 2,977 mRNAs and 1,527 lncRNAs were differential expressed in pigeon BFs over three developmental stages.
