A roadmap for global synthesis of the plant tree of life
Providing science and society with an integrated, up‐to‐date, high quality, open, reproducible and sustainable plant tree of life would be a huge service that is now coming within reach. However, synthesizing the growing body of DNA sequence data in the public domain and disseminating the trees to a diverse audience... -

Phylogenetic comparative methods improve the selection of characters for generic delimitations in a hyperdiverse Neotropical orchid clade
Taxonomic delimitations are challenging because of the convergent and variable nature of phenotypic traits. This is evident in species-rich lineages, where the ancestral and derived states and their gains and losses are difficult to assess. Phylogenetic comparative methods help to evaluate the convergent evolution of a given morphological character, thus...Bogarín, Diego ; Pérez-Escobar, Oscar A. ; Karremans, Adam P. ; Fernández, Melania ; Kruizinga, Jaco …

Repetitive DNA Restructuring Across Multiple Nicotiana Allopolyploidisation Events Shows a Lack of Strong Cytoplasmic Bias in Influencing Repeat Turnover
Allopolyploidy is acknowledged as an important force in plant evolution. Frequent allopolyploidy in Nicotiana across different timescales permits the evaluation of genome restructuring and repeat dynamics through time. Here we use a clustering approach on high-throughput sequence reads to identify the main classes of repetitive elements following three allotetraploid events,... -

Botanical Monography in the Anthropocene
Botanical monographs have been the gold standard for communicating comprehensive systematic information about plants for over 300 years. Monographs catalyse species discovery, biodiversity documentation and conservation, and facilitate downstream research on wild and cultivated plant species. Increased availability of DNA sequence data and digitised resources now provide powerful resources for...Grace, Olwen M. ; Pérez-Escobar, Oscar A. ; Lucas, Eve J. ; Vorontsova, Maria S. ; Lewis, Gwilym P. …

Plastome Evolution in the Hyperdiverse Genus Euphorbia (Euphorbiaceae) Using Phylogenomic and Comparative Analyses: Large-Scale Expansion and Contraction of the Inverted Repeat Region.
With 2,000 species, is one of the largest angiosperm genera, yet a lack of chloroplast genome (plastome) resources impedes a better understanding of its evolution. In this study, we assembled and annotated 28 plastomes from Euphorbiaceae, of which 15 were newly sequenced. Phylogenomic and comparative analyses of 22 plastome sequences...
