Phylogenetic relationships within Cornus (Cornaceae) based on 26S rDNA sequences.
Phylogenetic relationships within the dogwood genus Cornus have been highly controversial due to the great morphological heterogeneity. Earlier phylogenetic analyses of Cornus using chloroplast DNA (cpDNA) data (including rbcL and matK sequences, as well as restriction sites) and morphological characters suggested incongruent relationships within the genus. The present study generated sequence ...
متن کاملPhylogenetic analysis of nematodes of the genus Pratylenchus using nuclear 26S rDNA.
We used nucleotide sequences of the large subunit ribosomal genes (26S rDNA) to examine evolutionary relationships among species of the genus Pratylenchus (Order: Tylenchida, Family: Pratylenchidae), commonly known as root-lesion nematodes. Ten species of Pratylenchus were studied including, P. penetrans, P. crenatus, P. minyus, P. vulnus, P. thornei, P. musicola, P. coffeae, P. hexincisus, P. ...
متن کاملThe phylogeny of land plants inferred from 18S rDNA sequences: pushing the limits of rDNA signal?
Previous studies of the phylogeny of land plants based on analysis of 18S ribosomal DNA (rDNA) sequences have generally found weak support for the relationships recovered and at least some obviously spurious relationships, resulting in equivocal inferences of land plant phylogeny. We hypothesized that greater sampling of both characters and taxa would improve inferences of land plant phylogeny ...
متن کاملPhylogenetic analysis of Lymnaeid snails based on 18S rDNA sequences.
The 18S rDNA sequences of the six most common European Lymnaeidae species (Mollusca:Gastropoda:Basommatophora) have been obtained by direct PCR cycle sequencing and silver staining methods. The sequence alignment and secondary structures of the 18S rRNA gene of Lymnaea stagnalis, L. auricularia, L. peregra, L. palustris, L. glabra, and L. truncatula are analyzed. This gene proves to be a good m...
متن کاملphylogenetic location of the spirometra sparganum isolates from china, based on sequences of 28s rdna d1.
background: the phylogenetic location of chinese spirometra sparganum isolates remains unclear. the aim of this study was to explore the phylogenetic location of the spirometra sparganum isolates from china. methods: the 28s ribosomal dna (rdna) d1 sequences of 14 spirometra sparganum isolates collected from thirteen locations in china were analyzed by using neighbor-joining (nj), maximum parsi...
