Functional divergence of LhcSR and PsbS in zeaxanthin‐mediated non‐photochemical quenching

New Phytologist, Volume 250, Issue 5, Page 3042-3052, June 2026.
Summary To protect photosystem II from excess light, non‐photochemical quenching (NPQ) dissipates excess energy as heat. NPQ relies on trigger proteins, LhcSR in algae and PsbS in vascular plants, and the light‐regulated xanthophyll cycle, which interconverts violaxanthin and zeaxanthin through the opposite activities of violaxanthin de‐epoxidase and ...

Somatic genome‐doubling is the most parsimonious route to allopolyploidy

New Phytologist, Volume 250, Issue 5, Page 2845-2851, June 2026.
Summary The origin of a polyploid can hinge on a single errant cell division, a mistake in the cell cycle that leads to genome‐doubling and re‐writes the rules of chromosome pairing and segregation. In plants, the evolutionary significance of these errors is magnified by lack of an early sequestered germline, meaning somatic mutations can be heritable.

Grassland age and local adaptation shape drought resilience across semi‐natural grassland populations

New Phytologist, Volume 250, Issue 6, Page 3646-3660, June 2026.
Field sampling sites and mesocosm experimental design. Summary Increasing frequency and intensity of droughts threaten grassland ecosystems. Semi‐natural grasslands vary in age from ancient to younger sites established on former arable land. While species richness and composition are known to affect drought resilience, little is known about how ...

Built different: ER cisternae formed by the Arabidopsis Lunapark proteins differ in ultrastructure and affect ER–Golgi transport

New Phytologist, Volume 250, Issue 6, Page 3828-3845, June 2026.
The endoplasmic reticulum (ER) is a key structure in plant cells that helps produce and transport proteins. We discovered that different Lunapark proteins shape ER structures in distinct ways, affecting protein movement and secretion. Understanding how ER structure influences function can help improve plant‐based production of valuable compounds, such ...
