摘      要：Ulvacean green seaweeds are common worldwide;they formed massive green tides in the Yellow Sea in recent years,which caused marine ecological problems as well as a social issue.We investigated two major genera of the Ulvaceae,Ulva and Enteromorpha,and collected the plastid rbcL and nuclear ITS sequences of specimens of the genera in two sides of the Yellow Sea and analyzed them.Phylogenetic trees of rbcL data show the occurrence of five species of Enteromorpha(E.compressa,E.flexuosa,E.intestinalis,E.linza and E.prolifera) and three species of Ulva(U.pertusa,U.rigida and U.ohnoi).However,we found U.ohnoi,which is known as a subtropical to tropical species,at two sites on Jeju Island,Korea.Four ribotypes in partial sequences of 5.8S rDNA and ITS2 from E.compressa were also found.Ribotype network analysis revealed that the common ribotype,occurring in China,Korea and Europe,is connected with ribotypes from Europe and China/Japan.Although samples of the same species were collected from both sides of the Yellow Sea,intraspecific genetic polymorphism of each species was low among samples collected worldwide.
