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

open access: yesNew 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

open access: yesNew 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.

Irrigation using slightly saline water from emerging desalination technologies as a solution to short‐term drought

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 831-842, May 2026.
With global weather patterns becoming more extreme and unpredictable, sourcing reliable irrigation water is vital for improving food security and conserving drinking water in drought‐prone areas. Emerging desalination technologies, which are still in the development phase, could potentially provide large quantities of slightly saline water for ...
