  • Molecular marker C42257 for rapidly identifying genetic sex of and applications thereof
    Patent number: 11306365
    Abstract: The present invention provides a molecular marker C42257 for rapidly identifying genetic sex of Marsupenaeus japonicus and applications thereof. The nucleotide sequence of the molecular marker C42257 is shown in SEQ ID NO:1. The nucleotide sequences of the primer pair of molecular marker C42257 used for detection are C42257F: GGGGGACAA ACAGAGACA (SEQ ID NO: 2) and C42257R: ATCGGGGTGGATTTAGAA (SEQ ID NO: 3), respectively. The molecular marker C42257 is not affected by the tissue specificity of M. japonicus and the environment, and the steps are simple and the results are obvious. The genomic DNA of M. japonicus and the primer pair are subjected to PCR reaction and electrophoresis detection. If a target band appears at 183 bp, it is a female M. japonicus. The molecular marker can also promote the establishment of the seedling breeding technology of all-female or high-female-ratio M. japonicus. Therefore, it has a broad application prospect.
