Microorganisms Play Vital Role in Coral Health and Resilience
A recent study has revealed the significant role that certain microorganisms play in maintaining the health and resilience of coral reefs. Similar to the human microbiome, these microorganisms provide essential amino acids and B-vitamins to the coral host. The research team also identified specific microbes that contribute to the cycling of carbon and nitrogen within the coral species Acropora kenti, which are vital nutrients required for all life.
Functional Redundancy Ensures Microbial Community Health
The study found that various microbes encoded similar metabolic pathways, leading to functional redundancy. This redundancy ensures that even if some members of the microbial community are lost, the community as a whole can continue to perform in a healthy way. This discovery sheds light on the resilience of coral microbiomes and their ability to adapt to changing environmental conditions.
Mechanisms of Microbe-Coral Host Relationship
The researchers also observed how different microbes establish a relationship with their coral host. They identified several mechanisms through which the A. kenti microbiome can evade the coral’s immune system, allowing for a mutually beneficial relationship to be maintained. Understanding these mechanisms is crucial for preserving coral health and resilience.
Environmental Factors Shape Coral-Microbiome Associations
The study revealed that changes in the surrounding seawater, such as temperature and concentrations of dissolved inorganic nitrogen, were key factors in shaping the associations between A. kenti and its microbiome. This information is particularly important as corals face accelerated environmental changes due to anthropogenic climate change and pollution. Without adaptation, corals may experience mass mortality.
Contribution to Sustainable Development Goals
- SDG 14: Life Below Water – This research contributes to understanding the complex interactions within coral ecosystems, which is essential for the conservation and sustainable management of marine biodiversity.
- SDG 15: Life on Land – By studying the role of microorganisms in coral health and resilience, this research provides insights into the interconnectedness of terrestrial and marine ecosystems, highlighting the importance of preserving both.
The study titled A genome-centric view of the role of the Acropora kenti microbiome in coral health and resilience was published in the Springer Nature journal, Nature Communications. The authors of the study include Dr Messer, Professor Gene Tyson, Director of the Centre for Microbiome Research at Queensland University of Technology, Professor David Bourne of the Australian Institute of Marine Science and James Cook University, and their colleagues.
The research was funded by the Australian Research Council and the Queensland Government DSITIA Accelerate Partnerships award to the University of Queensland on behalf of the Australian Institute of Marine Science, the Australian National University, Bioplatforms Australia, the Great Barrier Reef Foundation, the Great Barrier Reef Marine Park Authority, and James Cook University.
