Brown marmorated stink bug, Halyomorpha halys (Stål), genome: putative underpinnings of polyphagy, insecticide resistance potential and biology of a top worldwide pest

open access: yesBMC Genomics, 2020
Background Halyomorpha halys (Stål), the brown marmorated stink bug, is a highly invasive insect species due in part to its exceptionally high levels of polyphagy. This species is also a nuisance due to overwintering in human-made structures.

Long wavelength-sensing cones of zebrafish retina exhibit multiple layers of transcriptional heterogeneity

open access: yesFrontiers in Cellular Neuroscience, 2023
IntroductionUnderstanding how photoreceptor genes are regulated is important for investigating retinal development and disease. While much is known about gene regulation in cones, the mechanism by which tandemly-replicated opsins, such as human long ...

The last common ancestor of most bilaterian animals possessed at least 9 opsins

open access: yesbioRxiv, 2016
The opsin gene family encodes key proteins animals use to sense light and has expanded dramatically since it originated early in animal evolution. Understanding the origins of opsin diversity can offer clues to how separate lineages of animals have ...

Beeinflussung der Augenentwicklung und Seidenfasermodifikation bei Spinnen mittels CRISPR‐Cas

open access: yesAngewandte Chemie, EarlyView.
Spinnen weisen einzigartige Merkmale auf, die in verschiedensten Forschungsbereichen von größtem Interesse sind. Das gezielte Verändern von Genen bietet neue Möglichkeiten, die Forschung voranzutreiben. In dieser Studie entwickelten wir ein CRISPR‐Cas9‐Protokoll für Spinnen, das Gen‐Knock‐outs/Knock‐ins ermöglicht, um zum einen Genfunktionen zu ...

Rapid adaptive evolution of colour vision in the threespine stickleback radiation. [PDF]

open access: yes, 2016
Vision is a sensory modality of fundamental importance for many animals, aiding in foraging, detection of predators and mate choice. Adaptation to local ambient light conditions is thought to be commonplace, and a match between spectral sensitivity and ...

Abnormal photoreceptor outer segment development and early retinal degeneration in kif3a mutant zebrafish [PDF]

open access: yes, 2016
Photoreceptors are highly specialized sensory neurons that possess a modified primary cilium called the outer segment. Photoreceptor outer segment formation and maintenance require highly active protein transport via a process known as intraflagellar ...

Opsin evolution and expression in Arthropod compound Eyes and Ocelli: Insights from the cricket Gryllus bimaculatus

open access: yesBMC Evolutionary Biology, 2012
Background Opsins are key proteins in animal photoreception. Together with a light-sensitive group, the chromophore, they form visual pigments which initiate the visual transduction cascade when photoactivated.

Visual pigment evolution in Characiformes: the dynamic interplay of teleost whole-genome duplication, surviving opsins and spectral tuning

open access: yesbioRxiv, 2019
Vision represents an excellent model for studying adaptation, given the genotype-to-phenotype-map that has been characterized in a number of taxa. Fish possess a diverse range of visual sensitivities and adaptations to underwater light making them an ...

A two-step method for identifying photopigment opsin and rhodopsin gene sequences underlying human color vision phenotypes. [PDF]

open access: yes, 2020
PurposeTo present a detailed, reliable long range-PCR and sequencing (LR-PCR-Seq) procedure to identify human opsin gene sequences for variations in the long wavelength-sensitive (OPN1LW), medium wavelength-sensitive (OPN1MW), short wavelength-sensitive (
