Relationships within the subfamily Lobelioideae in Campanulaceae are inferred from DNA sequence variation in the rbcL and ndhF genes, and the trnL-F region including the trnL intron and the trnL-F intergenic spacer. Results derived from Bayesian and parsimony analyses provide evidence for the long-suspected paraphyly of the genus Lobelia, comprising over 400 species as presently circumscribed. ...

Aneura pinguis is a thalloid liverwort species with broad geographical distribution. It is composed of cryptic species, however, the number of cryptic species within A. pinguis is not known. Five cpDNA regions (matK, rbcL, rpoC1, trnH-psbA and trnL-trnF) and the entire nuclear ITS region were studied in 130 samples of A. pinguis from different geographical regions. The relationships between the...

Few studies have addressed the phylogeography of species of the Cerrado, the largest savanna biome of South America. Here we aimed to investigate the phylogeographical structure of Dalbergia miscolobium, a widespread tree from the Cerrado, and to verify its concordance with plant phylogeographical and biogeographical patterns so far described. A total of 287 individuals from 32 populations were...

Historic events such as the uplift of mountains and climatic oscillations in the Quaternary periods greatly affected the evolution and modern distribution of the flora. We sequenced the trnL-trnF, ndhJ-trnL and ITS from populations throughout the known distributions of O. longilobus and O. taihangensis to understand the evolutionary history and the divergence related to the past shifts of habit...

In this study, 3 haplotypes were found in populations of Phellodendron amurense based on two combined cpDNA regions (psbA-trnH and trnT-trnL). Nucleotide diversity haplotype 0.43×10 -3 0.41, respectively at the level species. The AMOVA revealed that only 8.53% variation was explained by differences among geographical groups, whereas inter-population intrapopulation 18.32% 71.35% variation, resp...

Silene ciliata Pourr. (Caryophyllaceae) is a species with a highly disjunct distribution which inhabits the alpine mountains of the Mediterranean Basin. We investigated the phylogeny and phylogeography of the species to (a) clarify the long-suggested division of S. ciliata into two subspecies, (b) evaluate its phylogenetic origin and (c) assess whether the species' diversification patterns were...

The complex tectonic events and climatic oscillations in the Qinghai-Tibetan Plateau (QTP), the largest and highest plateau in the world, are thought to have had great effects on the evolutionary history of the native plants. Of great interest is to investigate plant population genetic divergence in the QTP and its correlation with the geologic and climatic changes. We conducted a range-wide ph...

Phylogenetic relationships, biogeography, and taxonomy of a group of taxa putatively related to the tetraploid Cardamine flexuosa were explored using sequences of the internal transcribed spacer region of nrDNA (ITS) and the trnL-trnF region of cpDNA. Taxon sampling focused on eastern Asia, North America, and Europe, and included 19 taxa represented by 177 and 182 accessions for each data set, ...

Delimitating species boundaries could be of critical importance when evaluating the species' evolving process and providing guidelines for conservation genetics. Here, species delimitation was carried out on three endemic and endangered Cycas species with resembling morphology and overlapped distribution range along the Red River (Yuanjiang) in China: Cycas diananensis Z. T. Guan et G. D. Tao, ...
