Blue- and Green-Absorbing Visual Pigments ofDrosophila: Ectopic Expression and Physiological Characterization of the R8 Photoreceptor Cell-Specific Rh5 and Rh6 Rhodopsins

open access: yes, 1999
Color discrimination requires the input of different photoreceptor cells that are sensitive to different wavelengths of light. TheDrosophilavisual system contains multiple classes of photoreceptor cells that differ in anatomical location, synaptic ...

Diterpenoid Diversity across Land Plants

open access: yesHelvetica Chimica Acta, Volume 109, Issue 4, April 2026.
Here we bridge the knowledge of diterpene chemical diversity, biosynthesis, and evolution from nonvascular mosses and liverworts to that known from vascular plants. ABSTRACT The diverse array of diterpenoid natural products stems from the ease of manipulating the promiscuity of diterpene cyclases.

UV-light-dependent binding of a visual arrestin 1 isoform to photoreceptor membranes in a neuropteran (Ascalaphus) compound eye11The cDNA sequence of the Ascalaphus Am Arr1 gene has been submitted to the EMBL data library under the accession number AJ303080

open access: yes, 2001
Arrestins are regulators of the active state of G-protein-coupled receptors. Towards elucidating the function of different arrestin subfamilies in sensory cells, we have isolated a novel arrestin 1, Am Arr1, from the UV photoreceptors of the neuropteran ...

Molecular insights into the eye evolution of bivalvian molluscs [PDF]

open access: yes, 2006
The intention of my PhD project was to gain more insights into eye evolution and to provide further evidence for the recently proposed idea that all eye-types found in eumetazoans derive from a common Pax6-dependent proto-type eye (Gehring and Ikeo, 1999)

Porphyrin‐Linked Antifungal Nanocarrier Promotes Plant Growth via UV RESISTANCE LOCUS 8‐Mediated Light Signalling Activation

open access: yesPlant Biotechnology Journal, Volume 24, Issue 3, Page 1518-1532, March 2026.
ABSTRACT Nanocarriers can improve pesticide delivery efficiency and reduce phytotoxicity, thereby supporting sustainable strategies for crop protection. Given this potential, it is essential to investigate their effects on crop physiology and development.

Intrinsically Photosensitive Retinal Ganglion Cells

open access: yes, 2011
Intrinsically photosensitive retinal ganglion cells (ipRGCs) respond to light in the absence of all rod and cone photoreceptor input. The existence of these ganglion cell photoreceptors, although predicted from observations scattered over many decades ...

Plant Cognition—An Empirical Primer: Evidence, Implications, and Ethics

open access: yesPhilosophy Compass, Volume 21, Issue 1, January/February 2026.
ABSTRACT Recent advances in plant biology suggest that plants engage in complex behaviours once thought to require nervous systems. This article surveys the empirical foundations of plant cognition, covering research on goal‐directed movement, decision‐making, anticipatory behaviour, communication, phytoacoustics, and plant neurobiology.

Signalling from neurones to glial cells in invertebrates

open access: yes, 1996
Recent work shows that glial cells in species throughout the animal kingdom appear to contribute to the functioning of the neurones and are equipped to receive signals from them. However, the detailed mechanisms of the signalling and its role in vivo are

Biological and Biologically Inspired Functional Nanostructures: Insights into Structural, Optical, Thermal, and Sensing Applications

open access: yesAdvanced Materials, Volume 37, Issue 51, December 23, 2025.
Biological and biologically‐inspired functional nanostructures with structural, thermal, optical, and sensing applications are reviewed. The role of nanoscale features in biological materials on performance is described, and their blueprints are used for bio‐inspired nanomaterials, synthesized using advanced techniques (i.e., photolithography, bio ...

Genome‐Wide Protein Interaction Analysis in Parasitic Gyrodactylus Flatworms–Fish Hosts System and Drug Target Identification

open access: yesAdvanced Science, Volume 12, Issue 45, December 4, 2025.
Genomic data offer a powerful tool for studying the molecular interactions between parasites and their hosts, but they remain scarce for parasitic monogenean flatworms. This study presents the first high‐quality phased genome assembly for monogeneans (Gyrodactylus kobayashii), and uses it to predict key interacting proteins between monogenean parasite ‐
