Pristionchus SSU sequence alignment. Sequences of 18 Pristionchus species and Koerneria sp. were aligned manually. Dashes (-) indicate identity to the majority consensus sequence at the top; asterisks (*) indicate alignment gaps. Numbering refers to the SSU segment obtained in this study. The sequences are available from the GenBank database under the accession codes [GebBank:DQ270018] to [GebBank:DQ270025], [GebBank:DQ419900] to [GebBank:DQ419904], [GebBank:EF216858] to [GebBank:EF216860], and [GenBank:EF623995] to [GenBank:EF623997].
