A biomimetic fly photoreceptor model elucidates how stochastic adaptive quantal sampling provides a large dynamic range [PDF]

open access: yes, 2017
Light intensities (photons/s/um2) in a natural scene vary over several orders of magnitude from shady woods to direct sunlight. A major challenge facing the visual system is how to map such a large dynamic input range to its limited output range, so ...

dPob/EMC is essential for biosynthesis of rhodopsin and other multi-pass membrane proteins in Drosophila photoreceptors

open access: yeseLife, 2015
In eukaryotes, most integral membrane proteins are synthesized, integrated into the membrane, and folded properly in the endoplasmic reticulum (ER).

Development of functional ectopic compound eyes in scarabaeid beetles by knockdown of orthodenticle [PDF]

open access: yes, 2017
Complex traits like limbs, brains, or eyes form through coordinated integration of diverse cell fates across developmental space and time, yet understanding how complexity and integration emerge from uniform, undifferentiated precursor tissues remains ...

Analysis of the genetically tractable crustacean Parhyale hawaiensis reveals the organisation of a sensory system for low-resolution vision

open access: yesBMC Biology, 2019
Background Arthropod eyes have diversified during evolution to serve multiple needs, such as finding mates, hunting prey and navigating in complex surroundings under varying light conditions.

How a fly photoreceptor samples light information in time [PDF]

open access: yes, 2017
A photoreceptor's information capture is constrained by the structure and function of its light-sensitive parts. Specifically, in a fly photoreceptor, this limit is set by the number of its photon sampling units (microvilli), constituting its light ...

Identification of actin filaments in the rhabdomeral microvilli of Drosophila photoreceptors. [PDF]

open access: yesThe Journal of cell biology, 1990
The phototransductive microvilli of arthropod photoreceptors each contain an axial cytoskeleton. The present study shows that actin filaments are a component of this cytoskeleton in Drosophila. Firstly, actin was detected in the rhabdomeral microvilli and in the subrhabdomeral cytoplasm by immunogold labeling with antiactin.

Polyphenolic Derivatives in Rhabdomeres of the Compound Eye [PDF]

open access: yesNature, 1962
THE chemical composition of a homogenized compound eye was reported by Langer1, but until now nothing was known about the components of rhabdomeres alone, although the presence of photosensitive substances in rhabdomeres has been anticipated by many investigators from a long time ago.

Subcellular localization of transcripts in Drosophila photoreceptor neurons: chaoptic mutants have an aberrant distribution [PDF]

open access: yes, 1990
Photoreceptor neurons in the Drosophila retina are long (100 mu) and narrow, providing a system for the study of the intracellular distribution of transcripts and proteins.

Phototransduction in Drosophila. [PDF]

open access: yes, 2015
Phototransduction in Drosophila's microvillar photoreceptors is mediated by phospholipase C (PLC) resulting in activation of two distinct Ca(2+)-permeable channels, TRP and TRPL.
