Comparison of whole chloroplast genome sequences to choose noncoding regions for phylogenetic studies in angiosperms: the tortoise and the hare III.
Nine newly explored regions of the chloroplast genome offer levels of variation better than the best regions identified in an earlier study and are therefore likely to be the best choices for molecular studies at low taxonomic levels.
The tortoise and the hare II: relative utility of 21 noncoding chloroplast DNA sequences for phylogenetic analysis.
The results of this study show that a survey using as few as three representative taxa can be predictive of the amount of phylogenetic information offered by a cpDNA region and that rate heterogeneity exists among noncoding cpDNA regions.
Everywhere but Antarctica: using a supertree to understand the diversity and distribution of the Compositae.
The results of molecular phylogenetic studies of members of tribes Helenieae, Heliantheae, and Eupatorieae (Asteraceae) and General systematics and proposed taxonomic changes in current classification are presented.

It is found that large expansions of gene families preceded the origins of green plants, land plants and vascular plants, whereas whole-genome duplications are inferred to have occurred repeatedly throughout the evolution of flowering plants and ferns.

Data from new samples were consistent with previous results and showed the genus to be a well-defined lineage within subtribe Helianthinae, and the affinities of 2 species, Viguiera similis and V. ludens, showed to lie outside the genus.
Phylogenetic Analyses of Trilliaceae based on Morphological and Molecular Data
The cladistic analyses strongly support the separation of Paris sensu lato into Daiswa, Kinugasa, and Paris and the monophyly of Trillium after removal of Pseudotrillium and Trillidium.
Phylogeny and biogeography of Eupatorium (Asteraceae: Eupatorieae) based on nuclear ITS sequence data.
The phylogenetic analysis of nucleotide sequence variation in the internal transcribed spacer (ITS) region of nuclear ribosomal DNA suggested that, following initial divergence in North America, Eupatorium reached Europe via dispersal during the late Pliocene with subsequent radiation in Asia.
Phylogenetic relationships in Helianthus (Asteraceae) based on nuclear ribosomal DNA internal transcribed spacer region sequence data
The phylogenetic placement of species with narrow geographic distributions in the extreme southeastern part of North America as the sister group (Phoebanthus) and as basally diverging branches of Helianthus in the ITS trees suggests that the ancestor to the genus may have been confined to this area prior to divergence and dispersal leading to the extant array of snpecies.
Evidence from chloroplast DNA restriction site analysis on the relationships of Scalesia (Asteraceae: Heliantheae)
The minimum of ten restriction site differences between Scalesia and Pappobolus of approximately 525 sites surveyed yielded an estimated sequence divergence of 0.19%, and an estimated time of divergence of approximately 1.2 million years.
INFRAGENERIC CLASSIFICATION OF HELIANTHUS (COMPOSITAE)
A formal infrageneric classification for the genus Helianthus was derived using phenetic, cladistic and biosystematic procedures and the 49 species were placed into four sections and seven series.
