The power of ionic movements in plants

open access: yesNew 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 ...

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

open access: yesNew 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.

Climate adaptation and functional constraints drive pollen evolution in Apiales

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2574-2587, March 2026.
Summary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

Modulation of SAL retrograde signalling promotes yield and water productivity responses in dynamic field environments

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1219-1233, February 2026.
Summary Chloroplast‐to‐nucleus retrograde signalling enables rapid stress responses in plants, but whether these signals accumulate to affect crop performance across entire growing seasons under field conditions remains unknown. We generated wheat mutants with targeted deletions in specific SAL gene copies from two distinct homeologous groups (TaSAL1 ...
