Widespread Variation in Retinochrome Spectral Absorbance Across Scallop Phylogeny

Molecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT Vision is a two‐step process, including phototransduction initiated by a retinal‐bound opsin photopigment, and subsequent photopigment regeneration wherein the inactive state is restored. Because retinal isomerization, or changing of the molecular structural conformation, drives the activation of opsin photopigments, the reverse process is a ...

The Role Of Octopamine In Syllable-Period Selective Phonotaxis In Female Cricket Acheta Domesticus [PDF]

, 2017
Female crickets respond phonotactically to the calls of conspecific males. Females\u27 phonotaxis has been reported to be variable, ranging from unselective to selectve in response to calls with varying syllable periods (30-90 ms).

Structural and Molecular Properties of Insect Type II Motor Axon Terminals

Frontiers in Systems Neuroscience, 2018
A comparison between the axon terminals of octopaminergic efferent dorsal or ventral unpaired median neurons in either desert locusts (Schistocerca gregaria) or fruit flies (Drosophila melanogaster) across skeletal muscles reveals many similarities.

Monoaminergic Systems in Flight-Induced Potentiation of Phonotactic Behavior in Female Crickets Gryllus bimaculatus

Insects
We have recently shown that experience of flight remarkably enhanced subsequent terrestrial phonotaxis in females in response to the male calling song. Here, we elucidated the possible roles of octopamine and serotonin in the enhancing effect of flying ...

Adrenergic Metabolic and Hemodynamic Effects of Octopamine in the Liver

, 2013
The fruit extracts of Citrus aurantium (bitter orange) are traditionally used as weight-loss products and as appetite suppressants. A component of these extracts is octopamine, which is an adrenergic agent.

Synthesis of N-alkylated octopamine derivatives and their interaction with octopamine receptor BmOAR1.

Journal of pesticide science
A series of N-alkylated octopamine derivatives was synthesized, and the structure-activity relationships of these derivatives with the silkworm Bombyx mori octopamine receptor BmOAR1 were evaluated using a secreted placental alkaline phosphatase reporter assay system.

Cloning and expression of a cDNA encoding a molluscan octopamine receptor that couples to chloride channels in HEK293 cells. [PDF]

, 1997
A cDNA encoding a G-protein-coupled receptor was cloned from the central nervous system of the pond snail Lymnaea stagnalis. The predicted amino acid sequence of this cDNA most closely resembles the Drosophila tyramine/octopamine receptor, the Locusta ...

Co-option of neurotransmitter signaling for inter-organismal communication in C. elegans

Nature Communications, 2019
Inter-organismal signaling is essential for animals to navigate and survive in their natural environment, yet is unclear how these chemical communication channels may have evolved.
