Abstract

The biogenic monoamine octopamine (OA) is a crucial regulator of invertebrate physiology and behavior. Since its discovery in the 1950s in octopus salivary glands, OA has been implicated in many biological processes among diverse invertebrate lineages. It can act as a neurotransmitter, neuromodulator and neurohormone in a variety of biological contexts, and can mediate processes including feeding, sleep, locomotion, flight, learning, memory, and aggression. Here, we focus on the roles of OA in female reproduction in insects. OA is produced in the octopaminergic neurons that innervate the female reproductive tract (RT). It exerts its effects by binding to receptors throughout the RT to generate tissue- and region-specific outcomes. OA signaling regulates oogenesis, ovulation, sperm storage, and reproductive behaviors in response to the female's internal state and external conditions. Mating profoundly changes a female's physiology and behavior. The female's OA signaling system interacts with, and is modified by, male molecules transferred during mating to elicit a subset of the post-mating changes. Since the role of OA in female reproduction is best characterized in the fruit fly Drosophila melanogaster, we focus our discussion on this species but include discussion of OA in other insect species whenever relevant. We conclude by proposing areas for future research to further the understanding of OA's involvement in female reproduction in insects.

她有胆量:章鱼胺在昆虫雌性繁殖中的作用。
生物源单胺章鱼胺(OA)是无脊椎动物生理和行为的重要调节因子。自20世纪50年代在章鱼唾液腺中发现OA以来,OA在不同的无脊椎动物谱系中涉及许多生物过程。在多种生物环境中,它可以作为神经递质、神经调节剂和神经激素,介导进食、睡眠、运动、飞行、学习、记忆和攻击等过程。本文主要介绍OA在昆虫雌性生殖中的作用。OA是在支配雌性生殖道(RT)的章鱼胺能神经元中产生的。它通过与整个RT中的受体结合来产生组织和区域特异性的结果。OA信号根据女性的内外部条件调节卵子发生、排卵、精子储存和生殖行为。交配会深刻地改变雌性的生理和行为。雌性的OA信号系统与交配过程中转移的雄性分子相互作用,并被其修改,从而引发交配后变化的一部分。由于OA在雌性生殖中的作用在果蝇黑腹果蝇中得到了最好的表征,因此我们将重点讨论这一物种,但在其他昆虫物种中也包括OA的讨论。最后,我们提出了未来的研究领域,以进一步了解OA在昆虫雌性生殖中的作用。

期刊介绍: The Journal is appropriate for papers on behavioral, biochemical, or cellular aspects of neural function, plasticity, aging or disease. In addition to analyses in the traditional genetic-model organisms, C. elegans, Drosophila, mouse and the zebrafish, the Journal encourages submission of neurogenetic investigations performed in organisms not easily amenable to experimental genetics. Such investigations might, for instance, describe behavioral differences deriving from genetic variation within a species, or report human disease studies that provide exceptional insights into biological mechanisms
