mGem: The two-decade evolution of in vivo coral microbiome manipulations.

Two decades of in vivo coral microbiome manipulations have identified common taxa and research gaps to improve coral health.

• Why it matters: Understanding how microbiome interventions can enhance coral resilience is crucial for reef conservation amid environmental threats.
• What they did: The review synthesizes research on coral hosts, probiotic taxa, and experimental designs from the past 20 years, highlighting methodological challenges and opportunities.
• The result: Findings suggest pathways to develop microbial tools for coral restoration and reef management, addressing current gaps and advancing probiotic applications.
