The CONSTANS flowering complex controls the protective response of photosynthesis in the green alga Chlamydomonas

Nature Communications, 2019
In flowering plants, the CONSTANS (CO) and Nuclear Factor Y (NF-Y) transcription factors connect light perception to floral induction. Here Tokutsu et al.

Interplay between high‐energy quenching and state transitions in Chlamydomonas reinhardtii: a single‐cell approach

New Phytologist, Volume 250, Issue 4, Page 2689-2705, May 2026.
Summary Studying cell‐to‐cell heterogeneity is essential to understand how unicellular organisms respond to stresses. We introduce a single‐cell analysis framework that enables the study of intercellular heterogeneity of photosynthetic traits, particularly their interactions within individual cells that have identical genotypes, cellular contexts and ...

Alloxazine derivatives as multifunctional agents for photodynamic therapy, cancer cell imaging, and cell proliferation inhibition

Photochemistry and Photobiology, Volume 102, Issue 3, Page 589-604, May/June 2026.
Alloxazine photosensitizers, molecularly engineered through sugar conjugation and methoxy substitution to enhance solubility, photodynamic potency, and fluorescence, enable image‐guided photodynamic therapy while inhibiting cancer cell growth in the absence of photoactivation.

Functional insights into the photoactive yellow protein family from homologs, multidomain proteins, and inferred pyp operons

Journal of Bacteriology
Photoactive Yellow Protein (PYP) is a model system for functional protein dynamics and a prototype of the PAS domain superfamily. It is a bacterial photoreceptor that triggers a range of responses in different bacteria: phototaxis, biosynthesis of photo ...

Genotype by light quality interaction on the growth and development of quinoa (Chenopodium quinoa) and the crop response to salinity

Frontiers in Plant Science
Quinoa (Chenopodium quinoa Willd.) is a highly nutritious crop with remarkable tolerance to drought and salinity, making it a promising model for developing resilient crops. In model plant species, photoreceptors have been shown to mediate abiotic stress

Here Today, Gone Tomorrow: Photobiology of a Short-Lived Landfast First-Year Sea Ice in Nuup Kangerlua, SW Greenland

Journal of Marine Science and Engineering
Across much of the Arctic, climate warming has reduced the extent of thicker and more persistent sea ice and increased the prevalence of thinner first-year ice.
