    Ca2+ sensor synaptotagmin-1 mediates exocytosis in mammalian photoreceptors

    Justin J Grassmeyer et al.
    The vesicular Ca2+ sensor synaptotagmin-1 regulates both fast phasic and slow tonic glutamate release at ribbon synapses of rod and cone photoreceptor cells.

    The β-alanine transporter BalaT is required for visual neurotransmission in Drosophila

    Yongchao Han et al.
    BalaT-dependent β-alanine trafficking pathway in retinal pigment cells is critical for maintaining synaptic transmission of photoreceptor neurons in Drosophila.

    The formation of the light-sensing compartment of cone photoreceptors coincides with a transcriptional switch

    Janine M Daum et al.
    Correlating changes in structure and gene expression in cone photoreceptors of mice daily, between birth and eye opening, created a resource that supports research in photoreceptor function, development, transplantation and repair.

    Parallel visual circuitry in a basal chordate

    Matthew J Kourakis et al.
    The ascidian Ciona integrates visual information from two photoreceptor types through convergent excitatory and disinhibitory circuits, thereby evoking swim behaviors.

    Light-dependent pathways for dopaminergic amacrine cell development and function

    Teona Munteanu et al.
    Rods, not ipRGCs, are the major retinal photoreceptor impacting development of dopaminergic signaling in the retina.

    Rhodopsin targeted transcriptional silencing by DNA-binding

    Salvatore Botta et al.
    Photoreceptor genomic binding of a 20 base-pair-long DNA sequence by a synthetic DNA-binding protein turns off Rhodopsin expression.

    Kinetics of the LOV domain of ZEITLUPE determine its circadian function in Arabidopsis

    Ashutosh Pudasaini et al.
    In the plant circadian clock photoreceptor ZEITLUPE, evolutionarily selected residues distinguish photocycle kinetics and allosteric signal transduction pathways to permit proper circadian timing.

    The primary structural photoresponse of phytochrome proteins captured by a femtosecond X-ray laser

    Elin Claesson et al.
    Time-resolved crystallography provides insight into the photochemical reactions in photoreceptor proteins, explaining the earliest steps of how plants, fungi and bacteria sense red light.
