Problems solved by technology

Using this method for identification, although the operation is simple and easy to learn and master, but the sample preparation is complicated, the band difference between samples is small, and it is easily affected by the sample collection method and various conditions in the experimental process. Therefore, in recent years, There are few reports on the identification of sturgeons, and they are mostly used for the assessment and determination of the individual health of sturgeons under artificial feeding conditions.

Embodiment

[0061] Using the sturgeon DNA to be identified as a template (extraction method adopts the extraction method of total genomic DNA in the previous 2), PCR amplification is carried out with microsatellite primer pair HLJS41 as primers, and the total PCR reaction system is 25 μL (template 1 μL, Mix12. .5 μL, upstream primer 0.5 μL, downstream primer 0.5 μL). The PCR reaction conditions were as follows: pre-denaturation at 95°C for 5 min; then 35 cycles, each cycle including denaturation at 94°C for 40 s, annealing at 55°C for 35 s, extension at 72°C for 50 s; and finally extension at 72°C for 10 min. PCR reaction products were detected by 10% non-denaturing polyacrylamide gel (Polyacrylamide Gel, referred to as PAAG) electrophoresis, and after the electrophoresis was completed, a modified silver staining method was used for staining-development-scanning and imaging, and the data results were saved. If there is a 255bp amplification product but not a 202bp amplification product, i...

Abstract

The invention discloses a primer and method for identifying Amur sturgeon, Siberian sturgeon and hybrid progeny thereof. The primer comprises Amur sturgeon primer pair and microsatellite primer pair HLJS41, wherein, the forward primer sequence of the Amur sturgeon is shown as SEQ ID No.1, the reverse primer sequence is shown as SEQ ID No.2; the forward primer sequence of the microsatellite primerpair HLJS41 is shown as SEQ ID No. 3, and the reverse sequence is shown as SEQ ID No. 4. By utilizing the primer and method, the Siberian sturgeon, the Amur sturgeon and the hybrid progeny thereof canbe distinguished simply and rapidly.

Description

technical field [0001] The invention belongs to the field of molecular biology, and in particular relates to primers and methods for identifying Siberian sturgeon, Sturgeon's sturgeon and their hybrid offspring. Background technique [0002] Sturgeon's sturgeon and Siberian sturgeon are two important cultured species in my country. Under natural conditions, Sturgeon's sturgeon is only distributed in the Heilongjiang (Amur River) water system. It is a unique species and an important economic fish in Heilongjiang. Its growth rate is fast, but its disease resistance is poor, it is not resistant to transportation, and it is too dependent on live bait It is difficult to domesticate and has a high mortality rate during the breeding process, which increases the risk of the sturgeon farming industry. The Siberian sturgeon is mainly distributed in Central Asia and Eastern Europe, and a small amount is distributed in the Irtysh River system in my country. Its growth rate is slow, but...
