The power of ionic movements in plants

New Phytologist, Volume 249, Issue 5, Page 2232-2240, March 2026.
Summary The movement of ion‐driven electrogenic events known as plant action potentials in the Venus flytrap Dionaea muscipula has first been recognized in Darwin's time. Besides electrophysiological techniques making use of current‐ and voltage‐recording electrodes, today an ever‐growing spectrum of tools has become available, that report online ...

Phytosulfokine signalling blocks mycotoxin toxicity in Arabidopsis and mediates suppression of cell death activated by bacterial microbe‐associated molecular patterns

New Phytologist, Volume 249, Issue 5, Page 2515-2530, March 2026.
Summary Fumonisin B1 (FB1) is a mycotoxin that disrupts ceramide biosynthesis and kills plants. Prior activation with bacterial microbe‐associated molecular patterns (MAMPs), such as components of bacterial flagella, effectively suppresses FB1‐induced cell death.

Amorphous silica biomineralizations in Schoenoplectus californicus (Cyperaceae): their relation with maturation stage and silica availability Biomineralizaciones de sílice amorfo en Schoenoplectus californicus (Cyperaceae): su relación con el estado...

Boletín de la Sociedad Argentina de Botánica, 2013
Summary: The factors involved on the silicification process in Cyperaceae are scarcely known. In this study we analyse the effect of maturation stage and silica availability on the production of amorphous silica biomineralizations in culms of ...

Finding balance: the dynamic interplay between H3K27me3 writers and erasers in regulating environmental plasticity and memory

New Phytologist, Volume 249, Issue 5, Page 2241-2250, March 2026.
Summary Subject to an ever‐changing world, plants must respond to harmful conditions and environmental fluctuations. Their evolutionary success can be attributed to their plasticity in both perceiving and integrating these variations to facilitate adaptation.

Revisiting the relationship between stomatal size and speed across species – a meta‐analysis

New Phytologist, Volume 249, Issue 5, Page 2338-2354, March 2026.
Summary The rate of stomatal opening and closure in response to changes in light affects leaf photosynthesis and water use. However, it is unclear how strongly stomatal size (SS) and density (SD) influence stomatal conductance (gs) kinetics, and whether variation arises from methodological differences, guard cell type or degree of amphistomaty.
