Bayesian, maximum‐likelihood, and maximum‐parsimony phylogenies, constructed using nucleotide sequences from the plastid gene region trnK‐matK, are employed to investigate relationships within the Cactaceae. These phylogenies sample 666 plants representing 532 of the 1438 species recognized in the family. All four subfamilies, all nine tribes, and 69% of currently recognized genera of Cactaceae are sampled. We found strong support for three of the four currently recognized subfamilies, although… 

Molecular phylogeny, origin and taxonomic implications of the tribe Cacteae (Cactaceae)

TLDR
The Cacteae seem to have originated in the Sierra Madre Oriental and then dispersed to the Mexican Plateau, where radiation and diversification occurred at the boundaries of the Miocene–Pliocene Epoch, and the development of the Mexico Plateau and the Trans-Mexican Volcanic Belt may have favoured the isolation of the CactEae.

Molecular phylogeny and taxonomy of the genus Disocactus (Cactaceae), based on the DNA sequences of six chloroplast markers

TLDR
Phylogenetic reconstruction was carried out with data from DNA sequences using the maximum parsimony and Bayesian inference criteria to explore the monophyly of the genus, its subgenera and its position within Hylocereeae and a new circumscription is proposed.

Phylogenetic Relationships in Echinocereus (Cactaceae, Cactoideae)

TLDR
The results support the monophyly of Echinocereus if E. pensilis is excluded and reestablished as the monotypic genus Morangaya and a re-evaluation of previously proposed infrageneric entities is suggested.

Molecular phylogeny of the large South American genus Eriosyce (Notocacteae, Cactaceae): Generic delimitation and proposed changes in infrageneric and species ranks

TLDR
A phylogeny‐informed infrageneric classification of the genus Eriosyce is presented and new combinations are proposed to update the nomenclature of species and sections, and some past taxonomic proposals have low phylogenetic support and should no longer be used.

A molecular phylogenetic approach to the systematics of Cylindropuntieae (Opuntioideae, Cactaceae)

    Cladistics : the international journal of the Willi Hennig Society
  • 2016
TLDR
This study proposes redefining the polyphyletic Grusonia excluding G. pulchella in order to recognize a strongly supported monophyletic genus and the acceptance of a monotypic Micropuntia avoiding a new combination into Pereskiopsis.

Splitting Echinocactus: morphological and molecular evidence support the recognition of Homalocephala as a distinct genus in the Cacteae

TLDR
Concatenated analyses with morphological and molecular data sets, show general agreement with previous independent phylogenetic proposals but with strong support in order to propose the recognition of a reduced Echinocactus and a monophyletic Homalocephala at the generic level.

Phylogeny and Circumscription of Cephalocereus (Cactaceae) Based on Molecular and Morphological Evidence

TLDR
This work reconstructs the phylogeny of the Cephalocereus group using molecular data from seven chloroplast regions, and proposes the transfer of all species of Neobuxbaumia, Cephalecreus, and PseudomitrocereUS to a single genus, in which Cephalancereuses takes priority over the other names.

Molecular phylogeny of Gymnocalycium (Cactaceae): assessment of alternative infrageneric systems, a new subgenus, and trends in the evolution of the genus.

TLDR
The results of the phylogenetic study confirm the monophyly of the genus, while supporting overall the available infrageneric classification based on seed morphology, and propose the name Scabrosemineum in agreement with seed morphology.

Phylogenetic analyses of Pilosocereus (Cactaceae) inferred from plastid and nuclear sequences

TLDR
Investigation of phylogenetic trees obtained points to a paraphyletic Pilosocereus, with P. bohlei and P. gounellei emerging nested in a clade of outgroup species (i.e. other genera of Cereinae), whereas the majority of species of the genus form one well supported clade.

Phylogeny and Biogeographic History of Astrophytum (Cactaceae)

TLDR
A phylogeny to date the origin of clades and infer the biogeographic patterns of Astrophytum is reconstructed and data suggest posterior diversification in the Late Miocene, during a transition to drier climates in North America.

Phylogenetic relationships in the cactus family (Cactaceae) based on evidence from trnK/ matK and trnL-trnF sequences.

TLDR
Cacti are a large and diverse group of stem succulents predominantly occurring in warm and arid North and South America, and trnL-trnF sequences from members of these clades were added to a combined analysis to improve resolution in three major groups of Cactoideae.

Molecular Phylogenetics of the Leafy Cactus Genus Pereskia (Cactaceae)

TLDR
To examine interspecific relationships within Pereskia, cpDNA restriction-site data and sequences from two non-coding regions of the plastid genome—the psbA-trnH intergenic spacer and the rpl16 intron identified three major clades; the relationship between these three clades and the rest of the Cactaceae remains unresolved, but the data do suggest that PeresKia may be paraphyletic.

Phylogeny of Opuntioideae (Cactaceae)

TLDR
These analyses suggest that Opuntioideae have geographic origin in west‐central South America and are marked by diminutive, succulent, often geophytic habit and are leafless at maturity.

Phylogenetic studies of Mammillaria (Cactaceae)--insights from chloroplast sequence variation and hypothesis testing using the parametric bootstrap.

TLDR
Phylogenies derived from the parsimony and Bayesian analyses indicate that Mammillaria is not monophyletic and that the genus Mammilloydia is embedded within a "core" group of mammillaria species.

Phylogenetic relationships in Peniocereus (Cactaceae) inferred from plastid DNA sequence data

TLDR
The phylogenetic relationships of Peniocereus (Cactaceae) species were studied using parsimony analyses of DNA sequence data and it is shown that the eight species of Peniospermia sensu stricto form a well-supported clade within subtribe Pachycereinae; P. serpentinus is also a member of this subtribe, but is sister to Bergerocactus.

The molecular phylogeny of Rebutia (Cactaceae) and its allies demonstrates the influence of paleogeography on the evolution of South American mountain cacti.

TLDR
It is found that the clade of cephalia-bearing cacti with naked pericarpels is centered in northeastern Brazil, whereas almost all other clades comprise Andean species, and the phylogenetic reconstructions based on parsimony and Bayesian approaches do not reflect the traditional delimitation of the tribes and of the large genera.

Molecular Systematics of Tribe Cacteae (Cactaceae: Cactoideae): A Phylogeny Based on rpl16 Intron Sequence Variation

TLDR
Parsimony analysis of plastid rpl16 sequences from 62 members of Tribe Cacteae, and four outgroup taxa yielded 1296 equally parsimonious trees of length 666, which established a highly pectinate topology, which delimited clades within the tribe that correspond to several previously considered generic groups.

Basal cactus phylogeny: implications of Pereskia (Cactaceae) paraphyly for the transition to the cactus life form.

TLDR
A new hypothesis of phylogenetic relationships at the base of the Cactaceae is presented, inferred from DNA sequence data from five gene regions representing all three plant genomes, which support a basal split between a clade of eight Pereskia species, centered around the Caribbean basin, and all other cacti.

Phylogenetic Analysis of Pachycereus (Cactaceae, Pachycereeae) based on Chloroplast and Nuclear DNA Sequences

TLDR
The results suggest that Pachycereus is paraphyletic and that several other genera may be resurrected to accommodate these new phylogenetic insights, and that the subtribe can be divided into three major clades.

Elusive Relationships Within Order Fabales: Phylogenetic Analyses Using matK and rbcL Sequence Data1

TLDR
A reappraisal of relationships within Fabales addresses past taxon sampling deficiencies, and employs parsimony and Bayesian approaches using sequences from the plastid regions rbcL and matK, and considers Polygalaceae as sister to the rest of the order Fabales with Leguminosae more closely related to Quillajaceae + Surianaceae the most likely hypothesis of interfamilial relationships.
