Embodiment 1

[0034] Material

[0035] Research object White shrimp inbred family group F 7 , F 8 , F 9 The first generation is a family of ridgetail white shrimp cultivated by the research group of Li Jian of the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences using a fully artificial indoor cultivation. The wild group of white prawns were collected from the sea area of ​​Jiangsu, F 1 The generation group is the offspring of the wild group, and 30 tails are randomly sampled from each group.

[0036] Primer

[0037] In this experiment, 2 pairs of microsatellite markers were screened to detect and identify the white shrimp family. The primers for amplifying microsatellite loci ES034 and ES096 were synthesized by Sangon Bioengineering (Shanghai) Co., Ltd., and their sequences are:

[0038] ES034

[0039] Forward primer: 5'ACTTCATCCACAAAGCAGAGGT 3',

[0040] Reverse primer: 5'GAAGAAGAGGAAGGTGGGGC3'.

[0041] ES096

[0042] Forward primer: 5'GCAATTTG...

Abstract

The invention discloses a microsatellite marker primer and method for authenticating an inbred family of palaemon carinicauda, and belongs to the field of molecular biology. Microsatellite marker names are ES034 and ES096. The invention further provides a method for authenticating the inbred family of the palaemon carinicauda by using the primer. According to the microsatellite marker primer and the method, the genetic relationship among individuals in a palaemon carinicauda group is authenticated by using two pairs of the microsatellite primers to judge the inbreeding level among the individuals in the group; when all the individuals have monomorphism segments at 146bp and 263bp, the authenticated group meets the requirement of inbred cultivation. The method supplies a basis for judgment of an inbred line.

Description

technical field [0001] The invention belongs to the field of molecular biology, and in particular relates to a method for using microsatellite markers to identify inbred families of the white shrimp. Background technique [0002] The ridge tail white shrimp belongs to the long arm shrimp family and the white shrimp genus, commonly known as white shrimp, small white shrimp and winter jasmine. It is mainly distributed in the shallow sea and low-salt waters along the coast of mainland China and the west coast of the Korean Peninsula, with the largest output in the Yellow and Bohai Seas. It is an important small and medium-sized economic shrimp in my country. White prawns have the advantages of wide environmental adaptability, miscellaneous food habits, short breeding cycle, and strong disease resistance, which greatly reduces the difficulty of artificial indoor breeding of white prawns. At the same time, adult white prawns are small and transparent in color and easy to Experim...
