Methylation-sensitive Amplification Polymorphism Analysis of Genomic DNA Methylation on Epinephelus lanceolatus,Epinephelus fuscoguttatus and Their Hybrid Generation
To investigate the generation mechanism of heterosis in fish hybrids,Epinephelus fuscoguttatus,Epinephelus lanceolatus and their hybrids populations were used as the objects of research,methylation-sensitive amplification polymorphism( MSAP) was used to analyze the DNA cytosine methylation of their genome. The results showed that the MSAP values of the three groups were 57. 18%,63. 16%,and 54. 76%,respectively.The full-methylation ratios of these populations were 31. 66%,39. 71% and 40. 00%,respectively,and...
