Abstract Many genera previously placed in the traditionally circumscribed Capparaceae are either unrelated or, more commonly, isolated lineages in the order Brassicales. This study examines the relationships of three of these orphan genera, Emblingia, Forchhammeria, and Tirania, in the context of a focused analysis of the core Brassicales. In order to assess relationships of these genera, analyses were conducted across Brassicales using chloroplast rbcL, ndhF, and matK sequence information… 

Phylogenetic placement of two enigmatic genera, Borthwickia and Stixis, based on molecular and pollen data, and the description of a new family of Brassicales, Borthwickiaceae

Borthwickia is described as a new family, Borthwickiaceae, for the genus, and was resolved as sister to the Forchhammeria-Resedaceae-Stixis-Tirania clade with moderate to strong support.

Systematics of Capparaceae and Cleomaceae: an evaluation of the generic delimitations of Capparis and Cleome using plastid DNA sequence data

The phylogenetic relationships in Capparaceae and Cleomaceae were examined using two plastid genes, ndhF and matK, to address outstanding systematic questions in the two families. Specifically, the

Contribution to ITS phylogeny of the Brassicaceae, with special reference to some Asian taxa

The findings support the expansion of Stevenia to include both Berteroella and Ptilotrichum, Sterigmostemum to include Oreoloma and one species of Anchonium, Crucihimalaya to include Transberingia and several species of Arabis, and Parrya to include Pseudoclausia.

Closing the gaps: phylogenetic relationships in the Brassicaceae based on DNA sequence data of nuclear ribosomal ITS region

The results fully support the recent findings that the tribes Schizopetaleae and Thelypodieae ought to be recognized as two distinct tribes instead of a single tribe, as well as provide some support for the re-establishment of the tribe Cremolobeae.

Phylogenetic relationships in the tribes Schizopetaleae and Thelypodieae (Brassicaceae) based on nuclear ribosomal ITS region and plastid ndhF DNA sequences.

Maximum parsimony, Bayesian, and maximum-likelihood analyses all support the separate recognition of three distinct and generally well-supported clades within the New World tribe Schizopetaleae.

Brassicaceae phylogeny inferred from phytochrome A and ndhF sequence data: tribes and trichomes revisited.

It is indicated that dendritic, medifixed, and stellate trichomes likely evolved independently several times in the Brassicaceae, and the evolution of different trichome morphologies using the AU test.

Phylogenetic and evolutionary features of the plastome of Tropaeolum pentaphyllum Lam. (Tropaeolaceae)

The sequencing data revealed that the T. pentaphyllum plastome is highly similar to the plastomes of other Brassicales, and plastid phylogenomic inference indicated a closed relationship between the families Tropaeolaceae and Akaniaceae, which formed a sister group to Moringaceae–Caricaceae.

Phylogeny of Capparaceae and Brassicaceae based on chloroplast sequence data.

Results of parsimony and likelihood analyses strongly support the monophyly of Brassicaceae plus Capparaceae, excluding Forchhammeria, and suggest the recognition of three primary clades-Cappar Families subfamily (subf.) Capparoideae, Cleomoidesae, and Br Jurassicaceae.

Phylogeny of the core Malvales: evidence from ndhF sequence data.

There has been extensive homoplasy in characters previously used to delineate major taxonomic groups in core Malvales, and it is suggested that /Malvatheca do not have as a synapormophy monothecate anthers, as has been previously supposed but, instead, may be united by dithecate, transversely septate (polysporangiate) anothers.

Molecular systematics of the Brassicaceae: evidence from coding plastidic matK and nuclear Chs sequences.

It is concluded that tribe Brassiceae might be the only monophyletic group of the traditional tribes, and tribes Lepidieae, Arabideae, and Sisymbrieae are not monophylets.

Molecules, morphology, and Dahlgren's expanded order Capparales

The major mustard-oil clade recovered from the rbcL analysis is congruent in many topological aspects with that found in a recent cladistic study of morphological characters, and in turn the molecular and morphological results confirm Dahlgren's radically expanded Capparales.

Parsimony analysis of DNA sequence variation in the chloroplast gene rbcL supports the monophyly of both families and attempts to identify morphological synapomorphies of the two‐family clade and of each family.

Phylogeny of the Portulacaceous Cohort Based on ndhF Sequence Data

A molecular phylogeny of the portulacaceous cohort showed that several generic circumscriptions remain inadequate, particularly that of Talinum sensu lato, which was polyphyletic in this analysis, and that all present classifications of the Portulacaceae include demonstrably non-monophyletic tribes.

Nucleotide sequences of rbcL confirm the capparalean affinity of the Australian endemis Gyrostemonaceae

Phylogenetic reconstruction based on parsimony robustly allies the family with other mustard oil-producing plants in Dahlgren's expanded order Capparales and confirms results from Rodman's cladistic analysis of traditional morphological features of these plants.

Phylogenetic placement of the enigmatic Western Australian genus Emblingia based on rbcL sequences

Treatment of Emblingia as a monotypic family, Emblingiaceae, within the order Brassicales is considered the most satisfactory solution.

To address the composition of the urticalean rosids, the relationships of the component families and analyze evolution of morphological characters, sequence variation is analyzed for a large sampling of these families and various rosid outgroups using rbcL, trnL-F, and ndhF plastid regions.
