Analysis of over 3300 single copy genes has produced a well-supported topology with some significant changes.

The Hidden Heritage of Pinyon Pines
Pinyon pine hybridization is widely acknowledged, but the frequency of and contributors to such interspecific mating remain largely unstudied. Pinus quadrifolia has three to four needles per fascicle, suggesting it is a...

Chromosome evolution in asymmetrical meiosis
Dog-roses have some special genetic tricks to cope with odd-ploidy.
Phylogeny, age and adaptive evolution of genus Allium
The genus Allium L., one of the largest monocotyledonous genera and one that includes many economically important crops with nutritional and medicinal value, has been the focus of classification or phylogeny studies for...
What creates Gentiana diversity in mountains?
The Qinghai-Tibetan Plateau (QTP) is extremely rich in species, but why? One recent explanation is the mountain‐geobiodiversity hypothesis (MGH) by Mosbrugger et al. The argument is that biodoversity happens when you...

Evolution of increased vigour associated with allopolyploidization in a newly formed invasive species
Polyploidy (whole genome duplication) is one of the most important processes in plant evolution. Most land plants have an evolutionary history that includes multiple polyploidization events. Allopolyploidy...

Temporal patterns of Brassicaceae diversification
Huang et al. propose that whole genome duplication events serve as a constant pump for continuous and high species diversification.

Diversification in Mediterranean firs occurred much earlier than expected
Mediterranean firs appeared millions of years earlier than was supposed, and likely through a single colonization event from Asia.
Evolutionary history of Pseudotaxus: old lineage, young populations
In southeast China there is a puzzle. Pseudotaxus chienii lives as a relict, a plant that used to have a much wider geographic range. Now it’s limited to comparatively few locations. This is common for many plants that...
Scaly Tree Ferns Have Slow and Steady Diversification
Did the Cyatheaceae become such a diverse family slowly over time, or in spurts? The largest molecular sampling yet points to gradual accumulation of species.
Distribution of Veronica polyploids is influenced by both habitat differentiation and historic glaciation
Species with higher ploidy levels prefer cooler, wetter habitats than diploids.
Arabidopsis halleri: a model system for studying population differentiation and local adaptation
Whilst studies on Arabidopsis thaliana have generally been highly molecular and/or genetic in nature, most studies using A. halleri have addressed adaptation and variation in adaptive traits in the species’ natural...
A diversity of lipid composition in the seeds and fruits of the palm family
Palms are vitally important due to their high vegetable oil production, which can occur in both fruits and seeds. The full range of lipid storage and composition, however, hasn’t been well understood across this large...
Identifying the biodiversity of the Mayan underworld
In the caves of Quintana Roo, there are not only stalactites hanging from the ceiling. There are tree roots too, but the roots of which trees?
