Advanced Science, Volume 13, Issue 6, 30 January 2026.The present study investigates a cone‐specific STX3 knockout model, displaying a complete loss of cone function, a later onset reduction in rod function, and photoreceptor cell death. A cone‐specific depletion of STXBP1 and ARR4 could be observed in this model.

Photoentrainment and Photopigments
Revista da Biologia, 2018 O arrastamento fótico é garantido pela ação de proteínas fotorreceptoras, que possuem propriedades muito particulares. Dentre as diversas proteínas fotossensíveis que surgiram ao longo do processo evolutivo, apenas algumas participam do arrastamento fótico.

Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract Benthic microalgal (BMA) communities contribute significantly to food webs, nutrient cycling, and carbon flows in intertidal habitats. However, the contribution of BMA to saltmarsh carbon stocks (“blue carbon”) is unclear. BMA and sediment total organic carbon (TOC) stocks were measured in an east coast American Atlantic saltmarsh, revealing ...

Basic and Applied Ecology, 2023 The presence and proportions of photopigments, which are responsible for the visual and physiological effects of light, vary between taxonomic groups. This leads to differing wavelength sensitivities ranging from ultraviolet (UV; 780 nm) and complicates ...

A missense variant (P10L) of the melanopsin (OPN4) gene in seasonal affective disorder [PDF]
, 2009 Background: Melanopsin, a non-visual photopigment, may play a role in aberrant responses to low winter light levels in Seasonal Affective Disorder (SAD).

Photopigment transmittance imaging of the primate photoreceptor mosaic [PDF]
The Journal of Neuroscience, 1996 We introduce a new technique for classifying many photoreceptors simultaneously in fresh, excised primate retina on the basis of their absorptance spectra. Primate retina is removed from the pigment epithelium and illuminated under a microscope from the same direction as in the intact eye.

Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract Predicting the effect of increased thermal unpredictability, for example in the shape of heatwaves on phytoplankton metabolic responses is ripe with challenges. While single genotypes in laboratory environments will respond to environmental fluctuations in predictable and repeatable ways, it is difficult to relate rapid evolutionary responses ...

Bleached pigment activates transduction in salamander cones. [PDF]
, 1995 We have used suction electrode recording together with rapid steps into 0.5 mM IBMX solution to investigate changes in guanylyl cyclase velocity produced by pigment bleaching in isolated cones of the salamander Ambystoma tigrinum.
