Histone Acetylation Modifications Affect Tissue-Dependent Expression of Poplar Homologs of C4 Photosynthetic Enzyme Genes

Frontiers in Plant Science, 2017
Histone modifications play important roles in regulating the expression of C4 photosynthetic genes. Given that all enzymes required for the C4 photosynthesis pathway are present in C3 plants, it has been hypothesized that this expression regulatory ...

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.

Measuring Daylight: A Review of Dosimetry in Daylight Photodynamic Therapy

Pharmaceuticals, 2019
Successful daylight photodynamic therapy (DPDT) relies on the interaction of light, photosensitisers and oxygen. Therefore, the ‘dose’ of light that a patient receives during treatment is a clinically relevant quantity, with a minimum dose ...

Weak acids produced during anaerobic respiration suppress both photosynthesis and aerobic respiration

Nature Communications, 2023
While photosynthesis transforms sunlight energy into sugar, aerobic and anaerobic respiration (fermentation) catabolizes sugars to fuel cellular activities.

Recent Advances in Nanomaterial‐Based Light Conversion for Agriculture

Aggregate, Volume 7, Issue 4, April 2026.
This figure illustrates three applications of nanophotoconversion materials for enhanced plant photosynthesis. These materials can directly target plant photosynthetic organs or be integrated into supplemental lights to optimize spectra. They can also be used in agricultural films to regulate sunlight for precise light control in protected agriculture.

Ultrafast energy quenching mechanism of LHCSR3-dependent photoprotection in Chlamydomonas

Nature Communications
Photosynthetic organisms have evolved an essential energy-dependent quenching (qE) mechanism to avoid any lethal damages caused by high light. While the triggering mechanism of qE has been well addressed, candidates for quenchers are often debated.

Far-red Fraction: An Improved Metric for Characterizing Phytochrome Effects on Morphology

Journal of the American Society for Horticultural Science, 2020
Phytochrome, a well-studied photoreceptor in plants, primarily absorbs in the red (R) and far-red (FR) regions and is responsible for the perception of shade and subsequent morphological responses.

When wuthering winds create fluttering fields: structural and biomechanical properties determine canopy light fluctuation properties of 10 wheat cultivars

New Phytologist, Volume 250, Issue 2, Page 934-948, April 2026.
Summary Wind‐driven plant movement generates rapid light fluctuations (windflecks), which can impact canopy photosynthesis. Targeting crop photosynthesis in dynamic light provides a potential path towards boosting yield. Here, we quantified how plant architecture and biomechanics modulate such windflecks across 10 high‐yielding cultivars of winter ...

Structure and distinct supramolecular organization of a PSII-ACPII dimer from a cryptophyte alga Chroomonas placoidea

Nature Communications
Cryptophyte algae are an evolutionarily distinct and ecologically important group of photosynthetic unicellular eukaryotes. Photosystem II (PSII) of cryptophyte algae associates with alloxanthin chlorophyll a/c-binding proteins (ACPs) to act as the ...

The Photoreceptor Components FaWC1 and FaWC2 of Fusarium asiaticum Cooperatively Regulate Light Responses but Play Independent Roles in Virulence Expression

Microorganisms, 2020
Fusarium asiaticum belongs to one of the phylogenetical subgroups of the F. graminearum species complex and is epidemically predominant in the East Asia area. The life cycle of F. asiaticum is significantly regulated by light.
