Phylogenetic relationships of Cranichidinae and Prescottiinae (Orchidaceae, Cranichideae) inferred from plastid and nuclear DNA sequences.
BACKGROUND AND AIMS Phylogenetic relationships of subtribes Cranichidinae and Prescottiinae, two diverse groups of neotropical terrestrial orchids, are not satisfactorily understood. A previous molecular phylogenetic study supported monophyly for Cranichidinae, but Prescottiinae consisted of two clades not sister to one another. However, that analysis included only 11 species and eight genera o...
متن کاملCellular ultrastructure and crystal development in Amorphophallus (Araceae).
BACKGROUND AND AIMS Species of Araceae accumulate calcium oxalate in the form of characteristically grooved needle-shaped raphide crystals and multi-crystal druses. This study focuses on the distribution and development of raphides and druses during leaf growth in ten species of Amorphophallus (Araceae) in order to determine the crystal macropatterns and the underlying ultrastructural features ...
متن کاملA phylogenetic study of Laeliinae (Orchidaceae) based on combined nuclear and plastid DNA sequences.
BACKGROUND AND AIMS Laeliinae are a neotropical orchid subtribe with approx. 1500 species in 50 genera. In this study, an attempt is made to assess generic alliances based on molecular phylogenetic analysis of DNA sequence data. METHODS Six DNA datasets were gathered: plastid trnL intron, trnL-F spacer, matK gene and trnK introns upstream and dowstream from matK and nuclear ITS rDNA. Data wer...
متن کاملIs Remusatia (Araceae) Monophyletic? Evidence from Three Plastid Regions
The genus Remusatia (Araceae) includes four species distributed in the tropical and subtropical Old World. The phylogeny of Remusatia was constructed using parsimony and Bayesian analyses of sequence data from three plastid regions (the rbcL gene, the trnL-trnF intergenic spacer, and the rps16 intron). Phylogenetic analyses of the concatenated plastid data suggested that the monophyly of Remusa...
متن کاملA new phylogeny for the genus Picea from plastid, mitochondrial, and nuclear sequences.
Studies over the past ten years have shown that the crown groups of most conifer genera are only about 15-25 Ma old. The genus Picea (spruces, Pinaceae), with around 35 species, appears to be no exception. In addition, molecular studies of co-existing spruce species have demonstrated frequent introgression. Perhaps not surprisingly therefore previous phylogenetic studies of species relationship...
