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.
