It is known that fertilization in bryophytes, as in animals, involves sperm and eggs. Recently, we isolated novel DNA from the sperm centrosome of the starfish Asterina pectinifera. In the present study, we examined whether the sperm of bryophytes contain this unique DNA. The total DNA in the sperm of M. polymorpha was used as a template for polymerase chain reaction (PCR) analysis performed using a centriole-specific DNA primer. Although this primer was designed to specifically amplify the centrosomal DNA of the starfish, it can amplify the centrosomal DNA of many other animals having a similar DNA sequence. The size of the amplified PCR products was approximately 500 bp, which is similar to that of the PCR products amplified from starfish. We determined the nucleotide sequence similarities between the PCR products amplified from the cultured cells of the moss Physcomitrella patens and from the sperm of the liverwort M. polymorpha. Our results show that DNA similar to that of the starfish centrosomal DNA exists in bryophytes and includes animal centrosomal DNA homologues and candidate centrosomal DNA.}, pages = {19--25}, title = {Detection of the Centrosomal DNA from the Sperm of Bryophyte Marchantia polymorpha L. and Physcomitrella patens}, volume = {18}, year = {2007} }
