Molecular phylogeny of the family Araceae as inferred from the nuclear ribosomal ITS data
The internal transcribed spacer regions of nuclear ribosomal DNA are widely used to infer phylogenetic relationships in plants. In this study, it was obtained the ITS sequences from 24 samples of Araceae in Iran, representing 3 genera: Arum L., Biarum Schott. and Eminium (Blume) Schott. Phylogenetic analyses were conducted by Bayesian inference and maximum Parsimony methods. Cladistic analysis ...
متن کاملPhylogeny and Biogeography of Tsuga (Pinaceae) Inferred from Nuclear Ribosomal ITS and Chloroplast DNA Sequence Data
Hemlock, Tsuga (Pinaceae), has a disjunct distribution in North America and Asia. To examine the biogeographic history of Tsuga, phylogenetic relationships among multiple accessions of all nine species were inferred using chloroplast DNA sequences and multiple cloned sequences of the nuclear ribosomal ITS region. Analysis of chloroplast and ITS sequences resolve a clade that includes the two we...
متن کاملRibosomal RNA sequence phylogeny is not congruent with ascospore morphology among species in Ceratocystis sensu stricto.
The genus Ceratocystis sensu stricto includes important fungal pathogens of woody and herbaceous plants. This genus is distinguished from species in Ceratocystis sensu lato by the presence of Chalara anamorphs. Ascospore shape has been used extensively in delineating Ceratocystis taxa, which show a large variety of ascospore shapes. Sequence analysis of one region of he 18S ribosomal RNA subuni...
متن کاملPhylogeny, Adaptive Radiation, and Historical Biogeography of Bromeliaceae Inferred from ndhF Sequence Data
Cladistic analysis of ndhF sequences identifies eight major bromeliad clades arranged in ladderlike fashion. The traditional subfamilies Tillandsioideae and Bromelioideae are monophyletic, but Pitcairnioideae are paraphyletic, requiring the description of four new subfamilies, recircumscription of Pitcairnioideae and Navioideae, the sinking of Ayensua, and description of the new genus Sequencia...
