Phylogenomics and the rise of the angiosperms
Angiosperms are the cornerstone of most terrestrial ecosystems and human livelihoods1,2. A robust understanding of angiosperm evolution is required to explain their rise to ecological dominance. So far, the angiosperm tree of life has been determined primarily by means of analyses of the plastid genome3,4. Many studies have drawn on...Zuntini, Alexandre R. ; Carruthers, Tom ; Maurin, Olivier ; Bailey, Paul C. ; Leempoel, Kevin …

Let’s pluck the daisy: dissection as a tool to explore the diversity of Asteraceae capitula.
Asteraceae, the daisy family, are one of the most diverse families of angiosperms and are predominant in many ecosystems, including grasslands, deserts, savannas and high-elevation mountains. They are characterized by a peculiar inflorescence, the capitulum, which mimics a flower, but is actually made up of many tightly grouped florets. The...Fu, Lin ; Palazzesi, Luis ; Pellicer, Jaume ; Balant, Manica ; Christenhusz, Maarten J M …

Giant Fern Genomes Show Complex Evolution Patterns: A Comparative Analysis in Two Species of Tmesipteris (Psilotaceae).
Giant genomes are rare across the plant kingdom and their study has focused almost exclusively on angiosperms and gymnosperms. The scarce genetic data that are available for ferns, however, indicate differences in their genome organization and a lower dynamism compared to other plant groups. Tmesipteris is a small genus of... -

Novel Insights into the Nature of Intraspecific Genome Size Diversity in Cannabis sativa L.
Cannabis sativa has been used for millennia in traditional medicine for ritual purposes and for the production of food and fibres, thus, providing important and versatile services to humans. The species, which currently has a worldwide distribution, strikes out for displaying a huge morphological and chemical diversity. Differences in Cannabis... -

Evolutionary patterns of genome size and chromosome number variation in Begoniaceae.
Cytological data resources are crucial to the study and understanding of the evolution of complex taxa. Recent research on the genus Begonia L. has provided a robust phylogenetic background for the analysis of evolutionary patterns across the group and has established that Begonia is variable in genome size and chromosome...Campos-Dominguez, Lucia ; Pellicer, Jaume ; Matthews, Andrew ; Leitch, Ilia J ; Kidner, Catherine A

A haploid pseudo-chromosome genome assembly for a keystone sagebrush species of western North American rangelands.
Increased ecological disturbances, species invasions, and climate change are creating severe conservation problems for several plant species that are widespread and foundational. Understanding the genetic diversity of these species and how it relates to adaptation to these stressors are necessary for guiding conservation and restoration efforts. This need is particularly...Melton, Anthony E ; Child, Andrew W ; Beard, Richard S ; Dumaguit, Carlos Dave C ; Forbey, Jennifer S …

Detecting Introgressed Populations in the Iberian Endemic Centaurea podospermifolia through Genome Size.
Based on results from previous studies, populations of the Iberian endemic Centaurea podospermifolia north of the Ebro River are considered genetically pure, while those southward are introgressed, with genetic input from C. cephalariifolia. This phenomenon is particularly relevant, especially given both the endangered and protected status for the species, which... -

Genome Size Doubling Arises From the Differential Repetitive DNA Dynamics in the Genus Heloniopsis (Melanthiaceae).
Plant genomes are highly diverse in size and repetitive DNA composition. In the absence of polyploidy, the dynamics of repetitive elements, which make up the bulk of the genome in many species, are the main drivers underpinning changes in genome size and the overall evolution of the genomic landscape. The...Pellicer, Jaume ; Fernández, Pol ; Fay, Michael F. ; Michálková, Ester ; Leitch, Ilia J.
