TLDR
A phylogenetic analysis of the Celastrales was performed using nuclear and plastid genes, and the results help delimit the Celastsrales and Celastraceae as morphologically more homogeneous taxa.Abstract:
A phylogenetic analysis of the Celastrales was performed using nuclear (18S, ITS 1, 26S rDNA) and plastid (atpB, matK, rbcL, trnL-F spacer) genes. In contrast to most previous studies, Celastrales and Malpighiales are resolved as being more closely related to one another than either are to Oxalidales. The Huaceae are well supported as the sister group to Oxalidales, not Celastrales, as had been previously proposed. The Lepidobotryaceae are unambiguously supported as sister to the clade consisting of Celastraceae and Parnassiaceae. The Parnassiaceae are well supported as members of an early branching lineage within Celastraceae, rather than as its sister group. Likewise, Pottingeria appears to be part of an early derived lineage of Celastraceae. Empleuridium is unambiguously supported as a derived member of Celastraceae, as are Brexia, Canotia, Siphonodon, Stackhousia, and Tripterococcus. Bhesa is unambiguously supported as a member of Malpighiales, though its relationships within the order remain...read more

TreeGraph 2: Combining and visualizing evidence from different phylogenetic analyses
TL;DR: TreeGraph 2, a GUI-based graphical editor for phylogenetic trees, is developed, which allows automatically combining information from different phylogenetic analyses of a given dataset (or from different subsets of the dataset), and helps to identify and graphically present incongruences.

TL;DR: It is confirmed that with large amounts of sequence data, most deep-level relationships within the angiosperms can be resolved and will be of broad utility for many areas of biology, including physiology, ecology, paleobiology, and genomics.

Malpighiales Phylogenetics: Gaining Ground on One of the Most Recalcitrant Clades in the Angiosperm Tree of Life
TL;DR: These data provide greatly increased support for the recent additions of Aneulophus, Bhesa, Centroplacus, Ploiarium, and Rafflesiaceae to Malpighiales; sister relations of Phyllanthaceae + Picrodendraceae, monophyly of Hypericaceae, and polyphyly of Clusiaceae.

A complete generic phylogeny of Malpighiaceae inferred from nucleotide sequence data and morphology
TL;DR: Comparison of floral morphology in Old World Malpighiaceae with their closest New World relatives suggests that morphological stasis in the New World likely results from selection by neotropical oil-bee pollinators and that the morphological diversity found inOld World flowers has evolved following their release from selectionby those bees.
