This work investigates the phylogenetic relationships within Grimmia Hedw. using 33 species of Grimmia and ten outgroup species from the Funariidae and the Dicranidae using a combination of two molecular markers and 52 morphological and anatomical characters. Plastid (trnL-trnF and rps4) DNA sequences were used to reconstruct the molecular phylogeny of Grimmia. The 33 chosen Grimmia species rep...

A new species of Primulaceae, Primula undulifolia, is described from the hilly area of Hunan province in south-central China. Its morphology and distributional range suggest that it is allied to P. kwangtungensis, both adapted to subtropical climate, having contiguous distribution and similar habitat, growing on shady and moist cliffs. Petioles, scapes and pedicels of them are densely covered w...

Cytoplasmic chloroplast DNA was explored to establish genetic relationships among Ficus carica cultivars and elucidate the molecular evolution of the species. The results suggest the occurrence of haplotype and nucleotide diversity. Conserved group I intron sequence motifs were detected and showed a common secondary structure, despite the presence of some mutations on their sequences. The neigh...

To determine the evolutionary relationships among all members of the genus Atractylodes (Compositae, Cardueae), we conducted molecular phylogenetic analyses of one nuclear DNA (nrDNA) region (internal transcribed spacer, ITS) and one chloroplast DNA (cpDNA) region (intergenic spacer region of trnL-F). In ITS and ITS + trnL-F trees, all members of Atractylodes form a monophyletic clade. Atractyl...

Phylogenetic relationships of Juncaceae and related families of Cyperales were investigated using DNA sequence data from the plastid rps16 intron, trnL intron, and trnL–F intergenic spacer. Results using parsimony analysis of the aligned matrices find Juncaceae and Cyperaceae to be monophyletic families, which form a clade sister to a monophyletic Thurniaceae that includes Prionium (Prioniaceae...
