摘要

珊瑚的耐热性在很大程度上取决于其微生物光合共生体(Symbiodiniaceae,俗称zooxanthellae)。因此,操纵共生体群落可以提高珊瑚在夏季热浪中的生存能力。虽然自然界中存在耐热和不耐热的共生物种,但即使是天然耐热共生物种的珊瑚也会在夏季热浪中出现白化现象。在高温条件下对共生藻培养物进行实验性进化(即实验室选择)已被成功地用于提高它们在体外以及在某些情况下重新引入珊瑚后的上层耐热性。在这篇综述中,我们介绍了这种干预措施的现状及其在珊瑚礁恢复中的潜在作用,并讨论了弥合实施差距所需的下一个关键步骤。

The use of experimentally evolved coral photosymbionts for reef restoration.

The heat tolerance of corals is largely determined by their microbial photosymbionts (Symbiodiniaceae, colloquially known as zooxanthellae). Therefore, manipulating symbiont communities may enhance the ability of corals to survive summer heatwaves. Although heat-tolerant and -sensitive symbiont species occur in nature, even corals that harbour naturally tolerant symbionts have been observed to bleach during summer heatwaves. Experimental evolution (i.e., laboratory selection) of Symbiodiniaceae cultures under elevated temperatures has been successfully used to enhance their upper thermal tolerance, both in vitro and, in some instances, following their reintroduction into corals. In this review, we present the state of this intervention and its potential role within coral reef restoration, and discuss the next critical steps required to bridge the gap to implementation.

期刊介绍: Trends in Microbiology serves as a comprehensive, multidisciplinary forum for discussing various aspects of microbiology, spanning cell biology, immunology, genetics, evolution, virology, bacteriology, protozoology, and mycology. In the rapidly evolving field of microbiology, technological advancements, especially in genome sequencing, impact prokaryote biology from pathogens to extremophiles, influencing developments in drugs, vaccines, and industrial enzyme research.
