The acquisition of stomata is one of the key innovations that led to the colonisation of the
terrestrial environment by the earliest land plants. However, our understanding of the origin …

Angiosperms show a remarkable range in genome size (GS), yet most species have small
genomes, despite the frequency of polyploidy and repeat amplification in the ancestries of …

The abrupt origin and rapid diversification of the flowering plants during the Cretaceous has
long been considered an “abominable mystery.” While the cause of their high diversity has …

A central challenge in plant ecology is to define the major axes of plant functional variation
with direct consequences for fitness. Central to the three main components of plant fitness …

The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …

Angiosperm diversity arises from trait flexibility and repeated evolutionary radiations, but the
role of genomic characters in these radiations remains unclear. In this opinion article, we …

Rapidly permineralized fossils can provide exceptional insights into the evolution of life over
geological time. Here, we present an exquisitely preserved, calcified stem of a royal fern …

Evolvability is best addressed from a multi-level, macroevolutionary perspective through a
comparative approach that tests for among-clade differences in phenotypic diversification in …

Cell sizes are linked across multiple tissues, including stomata, and this variation is closely
correlated with genome size. These associations raise the question of whether generic …

Polyploidy plays an important role in plant evolution, but knowledge of its eco‐physiological
consequences, such as of the putatively enlarged stomata of polyploid plants, remains …
