Heat‐evolved coral photosymbionts exhibit dampened stress responses across distinct physiological contexts

open access: yesNew Phytologist, Volume 251, Issue 4, Page 1755-1773, August 2026.
Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (

Rapid dehydration drives a nondiffusional drop in C3 photosynthesis that aligns with phosphate limitation

open access: yesNew Phytologist, Volume 251, Issue 3, Page 1127-1142, August 2026.
Schematic representation of the causal sequence through which rapid water loss imposes diffusive and nondiffusive restrictions on carbon assimilation. Summary Drought is an abnormally prolonged water deficit posing major challenges to plants. Stomatal closure has long been considered the primary factor limiting photosynthesis during the early stages of

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

open access: yesPlant, Cell &Environment, Volume 49, Issue 8, Page 5401-5420, August 2026.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Garden, greenhouse, or climate chamber? Experimental conditions influence whether genetic differences are phenotypically expressed

open access: yesPlant Biology, Volume 28, Issue 5, Page 1361-1372, August 2026.
Expression of genetic differences depends on the experimental environment as seen in flowering time differences between ancestors and descendants that emerge in climate chambers but not in greenhouse or garden conditions. Abstract Common‐environment experiments are important to study genetically based phenotypic variation within and among plant ...

Phycobilisomes: modular light‐harvesting systems of cyanobacteria and red algae

open access: yesThe Plant Journal, Volume 127, Issue 3, August 2026.
SUMMARY Phycobilisomes (PBSs) are supramolecular pigment–protein complexes that function as the principal light‐harvesting antennae in cyanobacteria, red algae (Rhodophyta), and glaucophytes, and to a lesser extent in cryptophytes. Because the intrinsic chlorophyll‐based antennae of the photosystems absorb poorly in the green region of the spectrum ...
