The invention belongs to the technical field of animal husbandry genetic breeding, and particularly relates to a mitochondrial SNP molecular marker related to egg laying performance of laying hens and application of the mitochondrial SNP molecular marker. The invention provides a mitochondrial SNP (Single Nucleotide Polymorphism) molecular marker related to the egg laying performance of laying hens, which is positioned at the 15944th bp of a chicken mitochondrial genome and has C / A / T polymorphism. The mitochondrial genome has maternal hereditary characteristics, systematic mitochondrial whole genome hereditary variation analysis is carried out to verify the genetic effect of the laying hen breeding trait mitochondrial gene, and the poultry genetic breeding theory is supplemented and perfected; moreover, a novel extranuclear genetic molecular marker and a variety breeding method are established, and the method has practical application value and important scientific significance.

The present invention relates to a composition for detecting a target gene based on cDNA synthesis using a ligation method that does not use reverse transcription and a method for multiple ligation-assisted recombinase polymerase amplification, and since a target gene may be detected through a visual change with only a short reaction time of about 30 minutes at room temperature without the synthesis of cDNA using reverse transcriptase, the present invention may be effectively used for point-of-care genetic molecular diagnosis of RNA viruses and the like.

The present application belongs to the field of animal models, and more specifically, a method for constructing an autism spectrum disorder mouse model by BAF155 conditional knockout mode is disclosed. By constructing a specific knockout BAF155 mouse, the effect of knockout BAF155 on OL development and myelination is observed. Further proved by the behavior experiment, the deletion of BAF155 in oligodendrocyte precursor cells will lead to the appearance of the core and characteristic ASD-like behavior phenotype of mice mainly with social preference disorder and repetitive stereotyped behavior. Therefore, the present application successfully constructs a new genetic molecular defect ASD animal model, and the advantage lies in that the target is clear, a single genetic molecular defect can be induced to study ASD, and a suitable and matched animal model for ASD caused by mutation of BAF155 is provided, which is helpful for precise diagnosis and subsequent intervention strategy.

This invention relates to a molecular marker for polymorphic SNPs in the Yangtze finless porpoise, its development method, and its application. Belonging to the field of DNA molecular marker technology, the nucleotide sequences of the polymorphic SNP molecular marker sites in the Yangtze finless porpoise are shown in SEQ ID NO:1-NO.19, and the primers used to amplify the SNP molecular marker sites are shown in Snpp 01-57. The SNP molecular markers provided by this invention are all derived from high-quality chromosome-level genomes of the Yangtze finless porpoise and are screened using resequencing data from three geographical populations. This allows for a more comprehensive detection of polymorphic SNP sites in the Yangtze finless porpoise genome. By utilizing KASP genotyping technology, genotyping of polymorphic SNP sites in the Yangtze finless porpoise can be performed efficiently and accurately, significantly reducing detection costs. This provides effective genetic molecular markers for population genetics studies such as genetic diversity assessment, genetic differentiation analysis, and kinship identification of the Yangtze finless porpoise and its closely related species.
