Style polymorphism in Nivenia (Iridaceae)
Heterostyly is widely distributed among the angiosperms, but detailed studies are limited to few taxonomic groups. Sánchez et al. (pp. 321–331) ascertain the presence of

Windows of opportunity in embryo development
Variation in mature seed size is the result of a complex array of interactions involving genes, genomes and environment that may change during development. Diggle et

Growth–differentiation balance in stressed juvenile plants
The growth–differentiation balance hypothesis states that there is a physiological trade-off between growth and secondary metabolism. Cella Pizarro and Bisigato (pp. 297–307) investigate

Gene dispersal in wild carrot populations
How far can a gene disperse? Historical and contemporary gene dispersal can be estimated from spatial genetic structure and paternity analysis, and Rong et al. (pp.

The waste of what we do?
Botanists can improve the plants that get harvested, but can they also improve what comes after?

Oxygen transport via aerenchyma in soybean
When in flooded soil, soybean, Glycine max, produces aerenchyma and hypertrophic stem lenticels. Shimamura et al. (pp. 277–284) investigate the oxygen dynamics in these tissues

Factors leading to hybrid lethality in Nicotiana
Hybrid lethality is a type of postzygotic isolation and is observed in some species of Nicotiana in association with genes encoded on the Q chromosome. Tezuka

Flower unisexuality in dioecious date palm
Dioecy has evolved independently several times during the evolution of flowering plants, but knowledge of the mechanisms involved is poor. Phoenix dactylifera is a dioecious species

Great Escapes – continued
There is another way to think of plant escapes: when I lived at Kew, there was a story about ‘bid for freedom of plants from Kew’

Genetic structuring in a large population of Arabidopsis
The perennial Arabidopsis lyrata is able to propagate both sexually and asexually, and this is expected to influence spatial genetic structure in the species. A fine-

Hourglass cell development in soybean seed coat
Hourglass cells (HGC) are prominent cells in the legume seed coat. Miller et al. (pp. 235–242) document HGC development in soybean, Glycine max, and relate

Even plants can have too much of a good thing
No doubt this will horrify Pat, but this is one of my favourite YouTube videos. If you’ve ever expressed a doubt about something, only to
