Vision is underpinned by phototransduction, a signaling cascade that converts light energy
into an electrical signal. Among insects, phototransduction is best understood in Drosophila …

Animal colours commonly act as signals for mates or predators. In many damselfly species,
both sexes go through a developmental colour change as adults, and females often show …

This study investigated whether irradiation of a specific light wavelength could affect the sex
differentiation of fish. We first found that the photoreceptor genes responsible for receiving …

Compound eyes are high-performing natural optical perception systems with compact
configurations, generating extensive research interest. Existing compound eye systems are …

Highlights•Most Odonate studies using-omics approaches have focused on
systematics.•Recent transcriptomic work has converged on a tree of life for Odonata.•Eight …

Background Vision is a crucial sense for the evolutionary success of many animal groups.
Here we explore the diversity of visual pigments (opsins) in the transcriptomes of amphipods …

Opsins allow us to see. They are G-protein-coupled receptors and bind as ligand retinal,
which is bound covalently to a lysine in the seventh transmembrane domain. This makes …

The krill species Euphausia superba plays a critical role in the food chain of the Antarctic
ecosystem. Significant changes in climate conditions observed in the Antarctic Peninsula …

Highlights•Color vision: more than just Opsins.•Spectral tuning differs between sexes and
species, and even within the same eye.•The distribution of different photoreceptor types …

BACKGROUND Opsins are crucial for animal vision. The identity and function of opsins in
Plutella xylostella remain unknown. The aim of the research is to confirm which opsin gene …
