Surprisingly, life history, soil nutrients, and range size were not key determinants.

‘Out of Iberia’: How Bristol rock cress got to where it is today
Is a population of rare cress found near Bristol, UK, a remnant of an ice age population, or is it part of a wider European population that survived in refugia somewhere?

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.

Genome size variation in the Hesperis clade was shaped by proliferation of DNA repeats
Most crucifer species (Brassicaceae) have small nuclear genomes (mean 1C-value 617 Mb). The species with the largest genomes occur within the monophyletic Hesperis clade (Mandáková et al.; also known as Clade E or...
Anthers prominence above the corolla enhances pollinator visitation in wild radish
Why are anthers where they are? A new study finds there might be more to anthers than purely functional tools.

Root border-like cells secrete antifungal defensin peptides
The South African endemic Brassicaceae species Heliophila coronopifolia (a semi-desert flower) produces root border-like cells (BLCs), the latter originally described in Arabidopsis thaliana. Four defensin peptides (Hc...
Evolution of Rainbow rockcress highlights Anatolia as a cradle of biodiversity
Phylogenetic and demographic analyses were employed to shed light on the species boundaries, evolutionary history and species diversity of genus Aubrieta (Brassicaceae). DNA sequence based mismatch-distribution and...
Something in the air? Volatiles influence mollusc attack on seedlings
Although pulmonate molluscs are the principal seedling herbivores in temperate grasslands and agriculture, we understand little about what drives seedling selection. Shannon et al. examined the roles of constitutive...
Pollinators and corolla shape robustness in Brassicaceae
How pollinators may influence the integration and developmental robustness of angiosperm flowers is still unknown. Using geometric morphometrics, Gómez et al. studied the evolution of the phenotypic variation, disparity...
Female sterility and hermaphrodites coexist in Cardamine amara
Tedder et al. report a new putative case of androdioecy in Swiss populations of the Arabidopsis relative, Cardamine amara (Brassicaceae).
Diversification and evolution of dispersal ability in Brassiceae
Increased dispersal ability in Brassiceae can influence macro-evolutionary processes, possibly by increasing the propensity for long-distance dispersal.
Phylogenetics, biogeography and trait evolution in tribe Arabideae
Karl and Koch provide a comprehensive phylogenetic analysis for the Arabideae species assemblage and test for association of trait and characters.
Live! It’s The Pollination Show!
A new paper in Annals of Botany shows live images of pollen behaviour during pollination.
