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

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

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.A fully protein‐based hydrogel integrated two orthogonal photoreceptors to enable reversible manipulation of stiffness with red/far‐red light and irreversible gel‐sol transitions with green light. Unexpectedly, high‐intensity red light results in attenuated stiffening and dark‐adaptation, arising from increased crosslinking dynamics in the ...

The transcriptional response of Arabidopsis leaves to Fe deficiency
Frontiers in Plant Science, 2013 Due to its ease to donate or accept electrons, iron (Fe) plays a crucial role in respiration and metabolism, including tetrapyrrole synthesis, in virtually all organisms.

Food Frontiers, Volume 7, Issue 4, July 2026.ABSTRACT Grape marc (GM) is a polyphenol‐rich winery byproduct that remains underutilized due to its complex fiber matrix, which limits the bioaccessibility of bound phenolics. While lactic acid fermentation (LAF) can enhance the release of these compounds, the strain‐specific metabolic fate of GM phenolics during digestion and colonic fermentation ...
