Abstract:

The free-floating population of Enteromorpha prolifera, which results in the blooms in Yellow Sea, has remarkable phenotypic variations compared to the attached population. We applied methylation-sensitive restriction fingerprinting (MSRF) to E. prolifera for methylation polymorphism with methylation-sensitive enzyme digestion. Our results showed that the free-floating sample might be abnormally hypermethylated at BstUI sites. It is suggested that these changes at epigenetic level may promote the rapid adaptation of E. prolifera to free-floating lives in Yellow Sea.

Key words: Enteromorpha prolifera, epigenetics, methylation, methylation-sensitive restriction fingerprinting
