Recent and recurrent polyploidy in Tragopogon (Asteraceae): cytogenetic, genomic and genetic comparisons
It is shown that multiple origins of a polyploid species not only affect patterns of genetic variation in natural populations, but also contribute to differential patterns of gene expression and may therefore play a major role in the long-term evolution of polyploids.

A molecular cytogenetic study on natural populations of a neoallopolyploid, Tragopogon miscellus, which formed multiple times in the past 80 y, uncovered massive and repeated patterns of chromosomal variation in all populations.

It is found that large expansions of gene families preceded the origins of green plants, land plants and vascular plants, whereas whole-genome duplications are inferred to have occurred repeatedly throughout the evolution of flowering plants and ferns.

UNLABELLED PREMISE OF THE STUDY Atripliceae (Chenopodiaceae), including Atriplex (300 spp.) as the largest genus of the family, are an ecologically important group of steppes and semideserts…
How to Handle Speciose Clades? Mass Taxon-Sampling as a Strategy towards Illuminating the Natural History of Campanula (Campanuloideae)
A short genomic region with high phylogenetic utility allowed this work to easily generate a comprehensive phylogenetic framework for the speciose Campanula clade and recovered 17 well-supported and circumscribed sub-lineages.
Featured Paper—ITS and ETS Sequence Data and Phylogeny Reconstruction in Allopolyploids and Hybrids
The results generally parallel those of phylogenetic studies that include F1 hybrids and their parents and use morphology, and the inclusion of a sequence from a hybrid or allopolyploid alter the overall topology in a major way.

The area and thickness of respiratory surfaces combine to match oxygen diffusion capacity to oxygen consumption rates in both air- and water-breathing vertebrates, providing insights into the long-standing effort to understand the structural attributes of organisms that underlie the body mass scaling of oxygen consumption.
Phylogeny of Campanuloideae (Campanulaceae) with Emphasis on the Utility of Nuclear Pentatricopeptide Repeat (PPR) Genes
This study represents the first inclusion of low-copy nuclear genes for phylogenetic reconstruction in Campanuloideae and reveals potential hybridization events for a number of taxa as well as obtaining support for the placement of two early diverging lineages that have previously been unresolved.

This study addresses the timing and rate of diversification in Tragopogon and shows that subclades of various plant taxa that occur in the same semi‐arid habitats of Eurasia also represent rapid radiations occurring during roughly the same window of time, suggesting similar causal events.
