Problems solved by technology

However, so far, there has been no report on genome scanning of this gene to find single nucleotide polymorphism (SNP), and it is impossible to fundamentally and overall detect the relationship between the SNP site of this gene and the growth traits of carp. sex

Embodiment 1

[0025] The cDNA sequence of IGF2b gene (AF402958) was retrieved from the NCBI (www.ncbi.nlm.nih.gov) database, and primers were designed (see Table 1 and Table 2).

[0030]

[0031]The exons of the IGF2b gene cDNA sequences of 3 yellow river carp and Jian carp to be tested were amplified by the primers provided in Table 1, and then the above IGF2b gene sequences of the Yellow River carp and Jian carp were amplified by the primers provided in Table 2 The above amplified products were subjected to agarose gel electrophoresis, and then the PCR products were gel-cut, recovered, purified and sequenced, and finally spliced ​​according to the sequence of the zebrafish genome sequence to obtain the complete IGF2b gene of the Yellow River carp and Jian carp. sequence.

[0032] The above specific process is as follows: t...

Abstract

The invention discloses a method for detecting carp IGF2b gene single nucleotide polymorphism and a primer. The method comprises the steps that on the basis of amplification of a whole genome of an exon and an intron of a carp IGF2b gene, the overall length of DNA of the gene is obtained, different modules are obtained through division for amplification to obtain SNP information of different fragments of the IGF2b gene, and scanning of the whole genome is completed. A result shows that the analysis method can be used for detecting carp IGF2b gene SNP loci related to economic characters, and can also be used for follow-up working such as analysis of the relation between the loci and the gene expression amount.

Description

technical field [0001] The invention belongs to the technical field of fish molecular design and breeding, and in particular relates to a SNP method for obtaining the whole genome of candidate genes in carp genome. Background technique [0002] Carp is an important freshwater economic fish with a wide breeding area, strong stress resistance and large output in my country. According to the "China Fishery Statistical Yearbook", in 2011 my country's bulk freshwater fish production reached 16.985 million tons, of which carp production was 2.7182 million tons. It can be seen that the production of carp occupies a pivotal position in our country. [0003] Insulin-like growth factor (insulin-like growth factor, IGF) is a polypeptide that promotes cell division, including IGF1 and IGF2, and its structure is similar to insulin. IGF is the intermediate messenger of growth hormone, that is, growth hormone first acts on IGF, and then IGF acts on target organs, and then exerts its role...
