Chicken whole-genome SNP chip and use thereof
Provided in the present invention is a chicken whole-genome SNP chip and application thereof. There are a total of 50,000 SNP loci on the chip: including 19,600 SNP loci for white-feather broilers, yellow-feather and partridge chickens having a MAF value greater than 0.05 and uniformly distributed across the genome which were derived from the data of the whole-genome resequencing of main indigenous chicken breeds in China and introduced chicken breeds; 14,000 SNP loci associated with economic traits, and 16,400 SNP loci for making up for the genomic regions that are not covered by the first two types of probes. The 50,000 SNP loci on the chicken whole-genome SNP chip of the present invention have DNA sequences represented by SEQ ID NOs. 1 to 50,000. The SNP loci on the chip are uniformly distributed across the whole genome, and associated with traits such as feed efficiency, meat production rate, lipid metabolism, meat quality, general resistance to diseases, reproduction and the like, and the chip has moderate through-put and low cost, and could be used universally for chicken breeds at indigenous and abroad. |

RNA sequencing methods
Described herein are methods for determining a sequence of a region of interest from an mRNA molecule. Sequenced polynucleotides can include a barcode region, a homopolymer region (e.g., a poly-A region), and a target region associated with the mRNA molecule. According to some methods, the barcode region omits the same base present in the homopolymer region. According to some methods, extension of the primer used for sequencing is stalled within the homopolymer region. According to some methods, sequencing flow cycles and the different barcode regions of the polynucleotides configured are such that the primer is extended to the end of the barcode region across the plurality of polynucleotides before being extended into the homopolymer region. According to some methods, two primers or a cleavable primer is used to separately sequence the barcode region and the target region. |
