To address the composition of the urticalean rosids, the relationships of the component families (maximally Cannabaceae, Cecropiaceae, Celtidaceae, Moraceae, Ulmaceae, and Urticaceae) and analyze evolution of morphological characters, we analyzed sequence variation for a large sampling of these families and various rosid outgroups using rbcL, trnL-F, and ndhF plastid regions. Urticalean rosids are derived out of a lineage including Barbeyaceae, Dirachmaceae, Elaeagnaceae, and Rhamnaceae, with… 

Figures and Tables from this paper

Infra-familial phylogeny of Urticaceae, using chloroplast sequence data

It is concluded that the circumscription of Urticaceae needs to be broadened to include taxa of Cecropiaceae, with Urticeae here expanded to include Poikilospermum and Elatostemeae.

Family-level relationships of Onagraceae based on chloroplast rbcL and ndhF data.

Results strongly support a monophyletic Onagraceae, with Ludwigia as the basal lineage and a sister-taxon relationship between Megacorax and Lopezia, and Gongylocarpus is supported as sister to Epilobieae plus the rest of Onagreae, although relationships within the latter clade have limited resolution.

On the origin of the fig: phylogenetic relationships of Moraceae from ndhF sequences.

The chloroplast gene ndhF is sequenced to examine relationships in Moraceae and to elucidate shifts in reproductive traits, and strong support for the sister-group relationship of a revised Castilleae with Ficus suggests that entomophily and involucral bracts encircling the flowers preceded the evolution of the syconium.

An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG IV

A revised and updated classification for the families of the flowering plants is provided and the use of bracketing families that could be included optionally in broader circumscriptions with other related families are expanded.

Molecular Phylogenetics of Core Brassicales, Placement of Orphan Genera Emblingia, Forchhammeria, Tirania, and Character Evolution

The core Brassicales is a biogeographically dispersed lineage that is comprised of many small and morphologically distinct clades plus the large crown group Brassicaceae s.

Phylogenetics of Morus (Moraceae) Inferred from ITS and trnL-trnF Sequence Data

Phylogenetic relationships of Morus are studied using sequence data from ITS of the nrDNA and the chloroplast trnL-trnF intergenic spacer to reveal that Morus, as currently circumscribed, is non-monophyletic.

Deep Insights Into the Plastome Evolution and Phylogenetic Relationships of the Tribe Urticeae (Family Urticaceae)

The phylogenomic analyses largely resolved major relationships across tribe Urticeae, supporting the monophyly of the tribe and most of its genera except for Laportea, Urera, and Urtica, which were recovered as polyphyletic with strong support.

Paraphyly in Tribe Onagreae: Insights into Phylogenetic Relationships of Onagraceae Based on Nuclear and Chloroplast Sequence Data

Abstract Onagraceae are a family of 17 genera in seven tribes, with the majority of species in tribes Onagreae and Epilobieae. Despite the species-richness of these two tribes, to date no

Evolution of a Charismatic Neotropical Clade: Molecular Phylogeny of Tabebuia s. l., Crescentieae, and Allied Genera (Bignoniaceae)

The phylogeny of Tabebuia presented here corresponds to the species groups established by Gentry, while at the same time highlighting the need for taxonomic revisions.



Further evidence for paraphyly of the Celtidaceae from the chloroplast gene matK

A phylogenetic analysis of the Urticales in its traditional circumscription and its putative affinities produced three equally most parsimonious trees, indicating that the Ulmaceae s.

Phylogenetics of the Hamamelidae and Their Allies: Parsimony Analyses of Nucleotide Sequences of the Plastid Gene rbcL

A parsimony analysis using nucleotide sequences of the plastid gene rbcL from 134 species found that Leitneriaceae are clearly a member of Sapindales.

Circumscription of Myrtales and their relationships to other rosids: evidence from rbcL sequence data

Parsimony analyses support a sister group relationship between the order Myrtales and a clade formed by an expanded Malvales, Sapindales, and an expanded Capparales.

Interfamilial Relationships in Myrtales: Molecular Phylogeny and Patterns of Morphological Evolution

The rbcL sequences of 50 taxa were analyzed using parsimony and maximum likelihood to provide a phylogenetic hypothesis of intraordi- nal relationships in Myrtales and suggest branch support for the basal split of Myrtale is weak.

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.

Family relationships of the enigmatic rosid generaBarbeya andDirachma from the Horn of Africa region

Molecular and morphological analyses indicate that Barbeya and Dirachma are closely related inter se as well as toRhamnaceae andElaeagnaceae, and it seems best to retain bothBarbeyaceae andDirachmaceae in their present circumscriptions, but in both cases in completely new positions in the angiosperm system.

Phylogenetic relationships of functionally dioecious FICUS (Moraceae) based on ribosomal DNA sequences and morphology.

The associations of pollinating fig wasps were congruent with host fig phylogeny and further supported a revised classification of Ficus and suggested that functionally dioecious figs are not monophyletic and that monoecious subg.

Angiosperm phylogeny inferred from 18S rDNA, rbcL, and atpB sequences

A phylogenetic analysis of a combined data set for 560 angiosperms and seven outgroups based on three genes, 18S rDNA, rbcL, and atpB representing a total of 4733 bp is presented, resulting in the most highly resolved and strongly supported topology yet obtained for angiosPerms.

Phylogeny of elms (Ulmus, Ulmaceae): molecular evidence for a sectional classification.

Cladistic analyses of chloroplast DNA restriction site variation were employed to examine phylogenetic relationships among 29 Ulmus accessions, including representatives from all proposed sections and subsections, and Zelkova serrata.

Urticales, Their Differentiation and Systematic Position

The Urticales constitute a group of plants with surprising diversity and confusing complexity, especially in the Moraceae round which family the present paper is centred. Main trends in the
