Microbes in the coral holobiont: partners through evolution, development, and ecological interactions

Area of Science:

• Marine Biology
• Microbiology
• Ecology

Background:

• Recent decades reveal microbial diversity and ubiquity, reshaping understanding of host-microbe roles beyond pathogens to symbionts.
• The human microbiome project highlights microbial influence on host health.
• Research is increasingly focusing on the role of microorganisms in coral reef ecosystems.

Purpose of the Study:

• To review current literature on coral-microbe interactions.
• To examine the role of these interactions in coral evolution, development, and ecology.
• To address how environmental changes may affect coral-microbial relationships.

Main Methods:

• Literature review of scientific publications on coral-microbe interactions.
• Analysis of existing research through the lens of four key questions regarding genomic, developmental, homeostatic, and ecological aspects.
• Synthesis of findings to understand the holobiont structure and function.

Main Results:

• Coral-microbe interactions significantly impact coral genomes, development, and ecological dynamics.
• Homeostasis between corals and their microbial symbionts is maintained through complex interactions.
• Understanding these relationships is vital for predicting coral responses to environmental shifts.

Conclusions:

• Elucidating the role of microorganisms in the coral holobiont is essential for understanding coral homeostasis.
• This knowledge is critical for assessing coral adaptation to changing environmental conditions.
• Further research into ecological approaches can deepen our understanding of multi-level coral-microbial interactions.
