Phylogenomics Yields New Insight Into Relationships Within Vernonieae (Asteraceae)

Phylogenomics in Asteraceae

Using genomic data to develop SSR markers for species of Chresta (Vernonieae, Asteraceae) from the Caatinga

Chresta is a genus mostly endemic to Brazil that presents several rupicolous species with naturally fragmented distributions. Aiming to facilitate studies about genetic diversity and structure in these species, we developed a set of 22 nuclear and 6 …

An empirical assessment of a single family-wide hybrid capture locus set at multiple evolutionary timescales in Asteraceae

Premise: Hybrid capture with high-throughput sequencing (Hyb-Seq) is a powerful tool for evolutionary studies. The applicability of an Asteraceae family-specific Hyb-Seq probe set and the outcomes of different phylogenetic analyses are investigated …

Phylogenomics Yields New Insight Into Relationships Within Vernonieae (Asteraceae)

Asteraceae, or the sunflower family, is the largest family of flowering plants and is usually considered difficult to work with, not only due to its size, but also because of the abundant cases of polyploidy and ancient whole-genome duplications. …

A fully resolved backbone phylogeny reveals numerous dispersals and explosive diversifications throughout the history of Asteraceae

The sunflower family, Asteraceae, comprises 10% of all flowering plant species and displays an incredible diversity of form. Asteraceae are clearly monophyletic, yet resolving phylogenetic relationships within the family has proven difficult, …

Chresta artemisiifolia (Vernonieae, Asteraceae), a new endangered species from a recently created protected area in the Brazilian Caatinga

Chresta artemisiifolia, a new species from northern Bahia, is described and illustrated. This species occurs on rock outcrops amidst the dry Caatinga domain, and is morphologically related with C. harleyi, C. hatschbachii , C. martii and C. …

Two New Rupicolous Species of Chresta (Asteraceae, Vernonieae) from the Brazilian Caatinga

Two new rupicolous and endangered species from the Caatinga are described and illustrated. Chresta heteropappa is restricted to the brejos de altitude (montane forests) from Northeastern Ceará, growing on granite inselbergs. Chresta subverticillata …

The systematic value of pollen morphology in Chresta Vell. ex DC. (Vernonieae, Asteraceae)

Chresta encompasses 15 species of Compositae, mostly restricted to the Brazilian Cerrado and Caatinga. Previous taxonomic studies have shown that there is variation in pollen types among species, but did not fully describe them. In order to provide …

The Compositae Tree of Life in the age of phylogenomics

Abstract Comprising more than 25?000 species, the Sunflower Family (Compositae or Asteraceae) is the largest family of flowering plants. Many of its lineages have experienced recent and rapid radiations, and the family has a deep and widespread …

Lychnophora spiciformis (Asteraceae: Vernonieae), a new species from Bahia, Brazil

Lychnophora spiciformis , a new species from Brazil, is here described and illustrated. The new species is endemic to the Chapada Diamantina in Bahia, Northeastern Brazil. Lychnophora spiciformis is characterized by its pseudoterminal congested …
