摘要
造礁石珊瑚的环境适应性取决于珊瑚共生功能体互作的分子调控机制,但这一机制尚未完全被阐明。近年来,随着高通量测序技术的发展,转录组学技术被广泛应用于珊瑚共生功能体的研究,成为解析珊瑚环境响应机制的关键工具,为揭示共生系统的分子互作网络提供了新视角。本文系统综述了转录组学在造礁石珊瑚环境适应性研究中的应用进展,重点阐述了不同环境胁迫下珊瑚共生功能体的转录响应,总结了珊瑚共生功能体各组分在应对不同环境胁迫时的差异响应机制。环境胁迫过程中珊瑚宿主和共生虫黄藻均表现出基因表达的可塑性,能够通过精确的转录调控网络来建立对环境胁迫的耐受性,并且能通过协同调控机制来维持共生关系的稳定。未来研究需进一步整合多组学数据,结合生理生态学验证,以全面揭示珊瑚共生功能体的调控网络。
The environmental adaptability of scleractinian corals depends on the molecular regulatory mechanisms underlying the interactions within the coral holobiont,yet these mechanisms remain incompletely elucidated.In recent years,with the advancement of high-throughput sequencing technologies,transcriptomics has been widely applied to the study of coral holobionts,emerging as a key tool for deciphering the environmental response mechanisms of corals.It has provided new perspectives for unraveling the molecular interaction networks within symbiotic systems.This paper systematically reviews the application progress of transcriptomics in the research on coral environmental adaptability,focuses on elaborating the transcriptional responses of the coral holobiont under different environmental stresses,and summarizes the differential response mechanisms of each component of the coral holobiont in coping with various environmental stresses.Under environmental stress,both the coral host and its associated Symbiodiniaceae exhibit gene expression plasticity,which enables them to establish stress tolerance through precise transcriptional regulatory networks and maintain symbiotic stability via coordinated regulatory mechanisms.Future research should further integrate multi-omics data and combine physiological and ecological validation to comprehensively reveal the regulatory networks of coral holobionts.
