Abstract:

The whole genome sequencing and related genetic map have been declared completed in chicken and many species. Because of the limitations of annotation methods, there are many missing novel genes and annotation errors of existed genes. RNA-Seq is a method for transcriptome studies based on second generation sequencing. In this study,we had sequenced cDNA library that were transcribed from all RNAs in ovaries of eight 300 days old Jinghai Yellow chickens(unanimous weight and the same rearing conditions, but there were difference on the number eggs and evenly divided into two groups: High laying performance and low laying performance) by using high-throughput sequencing technologies. 4 431 new transcripts were found by analysing transcriptome data, and many potential novel genes were found and annotated by comparing all new transcripts with GO, NR, Swiss-Prot and KEGG databases. Our work provided basic data for the further improvement of chicken genome and mining functional genes.
