TL;DR: The 2-locus combination of rbcL+matK will provide a universal framework for the routine use of DNA sequence data to identify specimens and contribute toward the discovery of overlooked species of land plants.

TL;DR: Nucleotide sequence data from three chloroplast genes, one nuclear gene and one mitochondrial gene were assembled for 173 species in 117 genera of liverworts, making this the largest molecular phylogeny of the group to date, providing support for the monophyly of the liverwort and for previously resolved backbone relationships within the Marchantiophyta.

TL;DR: It is shown that all available classifications in Old World Gesneriaceae are artificial and do not reflect natural relationships, and consistent topological relationships can be retrieved from data sets with missing data using subsamples and different combinations of gene sequences.

TL;DR: The didymocarpoid Gesneriaceae (traditional subfamus of the Cyrtandroideae excluding Epithemateae) as discussed by the authors are the largest group of old world geriaceae, comprising 85 genera and 1800 species.

TL;DR: A parsimony analysis of ndhF nucleotide sequences representing 24 species and 13 genera of Sterculioideae strongly supports the monophyly of the group and suggests the recognition of Argyrodendron as separate from Heritiera, supports Acropogon as different from Sterculia, and Tarrietia as part of heritiera.
