Beyond red/far‐red sensing: phytochrome perception of the marine light field by microalgae

New Phytologist, EarlyView.
Summary Phytochromes (PHYs) are a major group of photoreceptors, described as red and far‐red light sensors in land plants. Recent genomic and metagenomic explorations have revealed the presence of PHYs also in various eukaryotic microalgae originating from distinct endosymbiotic events.

Deep learning segmentation of non-perfusion area from color fundus images and AI-generated fluorescein angiography

Scientific Reports
The non-perfusion area (NPA) of the retina is an important indicator in the visual prognosis of patients with branch retinal vein occlusion (BRVO). However, the current evaluation method of NPA, fluorescein angiography (FA), is invasive and burdensome ...

Distinct Bleaching Resilience of Photosynthetic Plastid-Bearing Mollusks Under Thermal Stress and High CO2 Conditions

Frontiers in Physiology, 2018
The impact of temperature on photo-symbiotic relationships has been highly studied in the tropical reef-forming corals but overlooked in less charismatic groups such as solar-powered sacoglossan sea slugs. These organisms display one of the most puzzling

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

Photochemistry and Photobiology, EarlyView.
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.

Fungal photobiology: a synopsis

IMA Fungus, 2011
Fungi respond and adapt to many environmental signals including light. The photobiology of fungi has been extensively investigated, but in recent years the identification of the first fungal photoreceptor, WC-1 in the ascomycete Neurospora erassa, and ...

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 ...

Myopic shift in female mice after ovariectomy

Scientific Reports
Myopia is a global public health concern, with a higher prevalence in women than that in male. As the relationship between sex hormone and myopia remains unclear, we aimed to reveal the relationship between sex hormone and myopia by removing the ovaries ...

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 ...

PhotoBiology Station for Plant–Light Interactions Studies in Field Conditions

Journal of Agronomy and Crop Science, Volume 212, Issue 2, March 2026.
ABSTRACT Light is a primary source of energy for photosynthesis and a fundamental signal that governs plant morphology and growth dynamics through well‐orchestrated signalling pathways. In field conditions, light intensity and quality, as well as other variables, constantly change throughout the day.
