摘要

感觉受体处于生物体与其环境之间的界面,因此是生物创新的关键场所。在这里,我们调查了主要的感觉受体家族,以揭示新出现的进化模式。触觉、温度和光受体是动物祖先感官工具包的一部分,往往早于多细胞性和神经系统的进化。相比之下,化学感受器则表现出与化学环境的不同复杂性相关的特定品系扩展和收缩的动态历史。一个反复出现的主题包括从神经递质受体独立过渡到外界各种刺激的感觉受体。然后,我们概述了感觉受体多样化背后的进化机制,并重点举例说明了利用自然选择特征来识别新型感觉适应性的方法。最后,我们讨论了感觉受体作为进化热点推动了生殖隔离和物种分化,从而促成了动物令人惊叹的多样性。

Evolution of Sensory Receptors.

Sensory receptors are at the interface between an organism and its environment and thus represent key sites for biological innovation. Here, we survey major sensory receptor families to uncover emerging evolutionary patterns. Receptors for touch, temperature, and light constitute part of the ancestral sensory toolkit of animals, often predating the evolution of multicellularity and the nervous system. In contrast, chemoreceptors exhibit a dynamic history of lineage-specific expansions and contractions correlated with the disparate complexity of chemical environments. A recurring theme includes independent transitions from neurotransmitter receptors to sensory receptors of diverse stimuli from the outside world. We then provide an overview of the evolutionary mechanisms underlying sensory receptor diversification and highlight examples where signatures of natural selection are used to identify novel sensory adaptations. Finally, we discuss sensory receptors as evolutionary hotspots driving reproductive isolation and speciation, thereby contributing to the stunning diversity of animals.

期刊介绍: The Annual Review of Cell and Developmental Biology, established in 1985, comprehensively addresses major advancements in cell and developmental biology. Encompassing the structure, function, and organization of cells, as well as the development and evolution of cells in relation to both single and multicellular organisms, the journal explores models and tools of molecular biology. As of the current volume, the journal has transitioned from gated to open access through Annual Reviews' Subscribe to Open program, making all articles published under a CC BY license.
