Angiosperm phylogeny inferred from 18S rDNA, rbcL, and atpB sequences
A phylogenetic analysis of a combined data set for 560 angiosperms and seven outgroups based on three genes, 18S rDNA, rbcL, and atpB representing a total of 4733 bp is presented, resulting in the most highly resolved and strongly supported topology yet obtained for angiosPerms.

The results demonstrate that opportunity for island colonization and successful radiation may have been constrained to discrete time periods of profound climatic and geological changes in northern African and the Mediterranean.
Direct estimation of the mutation rate at dinucleotide microsatellite loci in Arabidopsis thaliana (Brassicaceae)
A survey of dinucleotide repeats across the entire Arabidopsis genome indicates that AT repeats are most abundant, followed by CT, and CA, which is consistent with the stepwise mutation model of microsatellite evolution.
Phylogenetic relationships and evolution of Crassulaceae inferred from matK sequence data.

A southern African origin of the family is suggested, with subsequent dispersal northward into the Mediterranean region and two separate lineages of European Crassulaceae subsequently dispersed to North America and underwent substantial diversification.
Inferring phylogeny at low taxonomic levels: utility of rapidly evolving cpDNA and nuclear ITS loci.
Results indicated that in preliminary studies, sampling strategy should include at least four exemplar taxa, and no single locus emerged as the best in all lineages for any of these measures of utility.
Elucidating deep-level phylogenetic relationships in Saxifragaceae using sequences for six chloroplastic and nuclear DNA regions
To elucidate relationships at deep levels within Saxifragaceae we analyzed phylogenetically a data set of sequences for six DNA regions, four representing the chloroplast genome (rbcL, matK,…
Bayesian inference of phylogeny: a non-technical primer
A basic introduction to Bayesian approaches to phylogeny reconstruction is attempted, which indicates that under most sets of realistic conditions, comparison of ML and MP indicates that these methods perform similarly and often result in highly concordant topologies.
Phylogenetics and Evolution of the Macaronesian Clade of Crassulaceae Inferred from Nuclear and Chloroplast Sequence Data
Given this estimate of phylogeny, the Macaronesian clade most likely evolved from herbaceous, continental ancestors; the woody habit evolved once in Aichryson tortuosum and again in the ancestor of the Aeonium clade.
