| utility of its1-5.8s-its2 sequences for species discrimination and phylogenetic inference of two closely related bucephalid digeneans (digenea: bucephalidae): dollfustrema vaneyi and dollfustrema hefeiensis. | the complete internal transcribed spacer 1 (its1), 5.8s ribosomal dna, and its2 region of the ribosomal dna from 60 specimens belonging to two closely related bucephalid digeneans (dollfustrema vaneyi and dollfustrema hefeiensis) from different localities, hosts, and microhabitat sites were cloned to examine the level of sequence variation and the taxonomic levels to show utility in species identification and phylogeny estimation. our data show that these molecular markers can help to discrimina ... | 2007 | 17497172 |
