Pathogens often secrete molecules that mimic those present in the plant host. Recent studies indicate that some of these molecules mimic plant hormones required for development

A comprehensive understanding of the systems behind vertical transport of water in tall trees is crucial when predicting the susceptibility of these long-lived organisms to

Possessing holocentric chromosomes may confer an advantage in clastogenic conditions and environments.

The rise of angiosperms should be studied as part of the global increase in biodiversity.

In experimental studies, rainfall-stimulated Triodia pungens masting precipitated a large but transitory spike in soil seedbank size and burning populations 6 months after this event triggered mass recruitment.

Aridification has been a major force in cycad evolution, says José Said Gutiérrez-Ortega. It helps to explain why cycads were capable to adapt and diversify in the modern habitats, even when they originated in the early evolution of land plants.

The overall results suggest that near-complete hybrid seed failure can evolve fairly rapidly and without apparent divergence in reproductive phenology/biology.

Divergent selection may have driven the calyx lobe length variation in series Sakawanum taxa, although the underlying mechanism is still not clear.

These findings imply that storage in herbs is probably governed by factors other than just the disturbance regime applied once in a growing season.

The underlying genetic causes of the switch to apomixes are not yet fully understood, but in Hypericum there is good evidence for the existence of ‘apomictic factors’.

Climatic changes and historical orogenies during the Quaternary might have played a significant role in determining the speciation and diversification patterns of primroses in Japan.

These findings highlight that canonical N:P thresholds have the potential to introduce a large uncertainty when used to detect plant nutrient limitations, suggesting that the error risks should be cautioned in future studies.
