Problems solved by technology

In terms of the reasons, apart from the deteriorating breeding environment and backward breeding technology, there is another important reason: no attention has been paid to the selection and preservation of seed oysters for many years, and there is a lack of good varieties; , such as slow growth, small size, weakened pearl breeding ability, etc.

Embodiment 1

[0025] Randomly take 50 Pinctada martensii individuals from the same group, after cleaning, take the adductor muscle tissue and weigh it with an electronic balance and record it one by one, then take a small piece of adductor muscle tissue and put it in 95% in ethanol and stored at -20°C. HiPure Universal DNA Kit (Guangzhou Meiji Biological Co., Ltd.) was used to extract the genomic DNA of the adductor muscle. For related operations, refer to the kit instructions. After the DNA was extracted, its integrity was detected by electrophoresis on 1.0% agarose gel, and the concentration and purity of the DNA were measured by an ultraviolet spectrophotometer, and stored at -20°C.

[0026] The detection primers for the SNP marker associated with adductor muscle weight of Pinctada martensii are:

[0027] ASSN815FI: TCCATCGTGGACAAACGTGTAA;

[0028] ASSN815RI:GTGTCAAAGTAAACTGTATCTCGTGCC;

[0029] ASSN815FO:TAGAATTGGCAAAGGAACAAGCAT;

Abstract

The invention discloses a detection primer marked by SNP and associated with pinctada martensi adductor muscle weight and application of the detection primer. The detection primer comprises the following substances:ASSN815FI: TCCATCGTGGACAAACGTGTAA; ASSN815RI: GTGTCAAAGTAAACTGTATCTCGTGCC; ASSN815FO: TAGAATTGGCAAAGGAACAAGCAT; ASSN815RO: AATAATTCCTAACAGGTGCCCGTC. Through the adoption of the detection primer marked by SNP and associated with pinctada martensi adductor muscle weight, SNP sites of the myostatin genes can be amplified, and the SNP sites are associated with the muscle weight obviously; according to the PCR amplification electrophotogram, the size of the adductor muscle weight between individuals can be compared visually, so that the detection primer can be directly used for follow-up molecular marker assistant breeding, for example, the detection primer can be used for selecting target characters in early growth stage, and then the specific individual is selected for variety breed.

Description

Technical field: [0001] The invention belongs to the technical field of aquatic animal genetics and molecular marker assisted breeding, and specifically relates to a detection primer of a SNP marker associated with adductor muscle weight of Pinctada martensii and an application thereof. Background technique: [0002] Pinctada martensii is the main species of pearl culture in my country and the world. Since the successful artificial breeding of Pinctada martensii in my country in 1965, the seawater pearl industry has developed rapidly and has become one of the pillar industries of mariculture in Guangdong, Guangxi and some coastal areas of Hainan. In the past 10 years, the quality and output of seawater pearls in my country have declined significantly, the international competitiveness has weakened, and the economic benefits of breeding have declined. In terms of the reasons, apart from the deteriorating breeding environment and backward breeding technology, there is another...
