The North American plums are a closely related group that are not easily circumscribed, have overlapping morphologies, and are known to hybridize. We previously showed that the North American plums are a closely related, monophyletic group of taxa with little to no cpDNA sequence divergence between taxa. In that study, we came to the unanticipated conclusion that relationships inferred among the taxa contrast sharply with previously defined groups based on morphological characters. Here the aim…

Phylogeny and Phylogeography of North American Castanea Mill. (Fagaceae) Using cpDNA Suggests Gene Sharing in the Southern Appalachians (Castanea Mill., Fagaceae)
It is observed that for three of these, leaf and twig morphology are reliable predictors of haplotype identity (especially outside of the southern Appalachians), and that the fourth lineage may have been recognized in the past as the hybrid taxon Castanea × neglecta because of its morphology that is intermediate between C. dentata and C. pumila.
Phylogeographic structure in three North American tent caterpillar species (Lepidoptera: Lasiocampidae): Malacosoma americana, M. californica, and M. disstria
The present study uses sequence variation in the mitochondrial cytochrome c oxidase 1 (COI) gene to examine the population genetic structure of the three widespread Malacosoma species (M. americana, M. californica, and M. disstria).
Phylogenetics and genomic patterns of speciation in Pinus with an empahsis on subgenus Strobus
It is demonstrated that Pinus chiapensis is a distinct species, but that taxonomy is not universally accepted, and the absence of allelic coalescence is a severe constraint in the application of phylogenetic methods in Pinus.
New infrageneric classification of Abies in light of molecular phylogeny and high diversity in western North America
Phylogenetic results show that western North America is home to an exceptionally high diversity of fir lineages, which is further corroborated by the cuticle morphology and internal transcribed spacer genotypes based on the length differences.
Evolution and Phylogeography of the North American genus Boechera (Brassicaceae)and the Evolution of Apomixis
The chloroplast gene pool in Boechera pre-dates speciation in respect to the investigated markers, which indicates rapid speciation which probably happened in the second half of the quaternary.
Polyphyly of the Padus group of Prunus (Rosaceae) and the evolution of biogeographic disjunctions between eastern Asia and eastern North America
The results support two disjunctions between eastern North America and Eurasia within the Padus group and Prunus subgenus Padus is shown to be polyphyletic.
Revisiting monophyly in Haworthia Duval (Asphodelaceae): Incongruence, hybridization and contemporary speciation
It is hypothesized that Haworthia is undergoing a contemporary and explosive radiation in southern Africa, driven in part by local adaptation to relatively fine-grained ecological heterogeneity of soils and microclimate.
Phylogenetic relationships among Japanese flowering cherries (Prunus subgenus Cerasus) based on nucleotide sequences of chloroplast DNA
It is concluded that Japanese flowering cherries have experienced complicated speciation arising from hybridization and could be identified by many morphological characters.
A new look at the genus Crocus L. phylogeny and speciation: Insight from molecular data and chromosome geography
HGT, deep coalescence, gene duplication and deletion and perhaps barcode specification are among the molecular events which played role in the species diversification of the genus Crocus, and the present study showed close genetic affinity between three species of C. sativus.
Genome origin, historical hybridization and genetic differentiation in Anthosachne australasica (Triticeae; Poaceae), inferred from chloroplast rbcL, trnH-psbA and nuclear Acc1 gene sequences
The aims are to demonstrate the process of polyploidization events and to explore the differentiation patterns of the St genome following geographic isolation and to assess the divergence within A. australasica and between Anthosachne and its putative progenitors.


Addressing the "hardest puzzle in American pomology:" Phylogeny of Prunus sect. Prunocerasus (Rosaceae) based on seven noncoding chloroplast DNA regions.
Prunus subg. Prunus sect. Prunocerasus (Rosaceae) is a North American taxon with 17 commonly recognized taxa. To test the hypothesis of monophyly for the section we sequenced the trnG and rpL16
Incongruence between chloroplast and species phylogenies in Eucalyptus subgenus Monocalyptus (Myrtaceae).
It is highlighted that the geographical pattern to cpDNA variation in Eucalyptus may be an important source of information on past plant distributions in Australia and the transfer of cpDNA through hybridization between lineages is the most likely explanation for the observed sharing of cp DNA across series.
The historical patterns inferred for populations of Piriqueta are consistent with known biogeographical events, historical vegetation change, and the concordant patterns of multiple Pleistocene refugia that have been observed for a number of other taxa in southeastern North America.
Phylogeny and Systematics of Prunus (Rosaceae) as Determined by Sequence Analysis of ITS and the Chloroplast trnL-trnF Spacer DNA
The objective of this study was to reconstruct the phylogeny of Prunus with the purpose of reviewing previously described taxonomic relationships and providing a basis for studies of morphological evolution in the genus.
Phylogeny, biogeography, and processes of molecular differentiation in Quercus subgenus Quercus (Fagaceae).
The biogeographic hypothesis that all major oak lineages evolved locally at middle latitudes within the general distribution of their fossil ancestors was fully supported and a New World origin for the widespread white oaks of the Northern Hemisphere was suggested.
Chloroplast DNA evidence for reticulate evolution in Eucalyptus (Myrtaceae)
The cpDNA results provide the strongest evidence to date that hybridization has had a widespread impact on a eucalypt species and indicate that reticulate evolution may be occurring on an unappreciated scale in E. globulus.
Reticulate evolution in kiwifruit (Actinidia, Actinidiaceae) identified by comparing their maternal and paternal phylogenies.
The phylogenetic analysis of chloroplast and mitochondrial restriction site and sequence data confirms the hypothesis that the four currently recognized sections are not monophyletic and provides evidence for multiple origin of at least two polyploid taxa.
Chloroplast DNA phylogeography of the hornbeam in Europe: Evidence for a bottleneck at the outset of postglacial colonization
The phylogeography of the hornbeam is studied using cpDNA to investigate whether this postglacial recolonisation had led to a loss ofchloroplast DNA diversity, and similar refugia in Italy and in the Balkans for both Carpinus species.
Chloroplast DNA phylogeography of Fagus crenata (Fagaceae) in Japan
The distribution of the two major cpDNA clades suggests that there were two migration routes in the history of F. crenata; one along the Japan Sea and the other along the Pacific Ocean side of the Japanese Islands.

The evolutionary history of the chloroplast genomes of two closely related pine species, Pinus hartwegii Lindl and P. montezumae, are addressed using coalescent theory and some of the statistical tools that have been developed from it during the past two decades.
