A Cladistic Analysis of ndhF Sequences from Representative Species of Saintpaulia and Streptocarpus Subgenera and Streptocarpella (Gesneriaceae)

Nuclear DNA content in Sinningia (Gesneriaceae); intraspecific genome size variation and genome characterization in S. speciosa.

The Gesneriaceae (Lamiales) is a family of flowering plants comprising >3000 species of mainly tropical origin, the most familiar of which is the cultivated African violet (Saintpaulia spp.). Species of Gesneriaceae are poorly represented in the lists of taxa sampled for genome size estimation; measurements are available for three species of Ramonda and one each of Haberlea, Saintpaulia, and St...

The Phylogenetic Relationships of Lembocarpus and Goyazia (Gesneriaceae) Based on ndhF Sequences

The phylogenetic relationships of Goyazia and Lembocarpus are investigated based on cladistic analysis of ndhF sequences. Both genera are currently classified in the tribe Gloxinieae, but both are poorly known. Based on its floral morphology, the classification of Goyazia in Gloxinieae is not controversial. Lembocarpus may be placed in Gloxinieae, Episcieae, or Sinningieae. The acaulescent, tub...

Solanum Phylogeny Inferred from Chloroplast Dna Sequence Data

A data set derived from gene sequences of ndhF is used to deduce phylogenetic relationships among the subgenera of Solanum, among related genera of the tribe Solaneae, and within selected Solanum clades. Complete ndhF sequences were obtained for 12 species of Solanum, representing five of the seven subgenera. ndhF sequences also were obtained from species of Capsicum, Cyphomandra, Datura, Jalto...

Tribal Relationships in the Gesneriaceae: Evidence from DNA Sequences of the Chloroplast Gene ndhF

Distinct Processes Drive Diversification in Different Clades of Gesneriaceae.

Using a time-calibrated phylogenetic hypothesis including 768 Gesneriaceae species (out of [Formula: see text]3300 species) and more than 29,000 aligned bases from 26 gene regions, we test Gesneriaceae for diversification rate shifts and the possible proximal drivers of these shifts: geographic distributions, growth forms, and pollination syndromes. Bayesian Analysis of Macroevolutionary Mixtur...
