ocean-microbiome
The ocean microbiome refers to the complex communities of microorganisms—bacteria, archaea, fungi, protists, and viruses—that associate with marine organisms and environments. Understanding these microbial communities is increasingly relevant to plant science because marine microbiomes offer insights into how symbiotic and pathogenic relationships evolve, which can inform our understanding of analogous plant-microbe interactions in terrestrial ecosystems. Additionally, marine microorganisms are a rich source of novel bioactive compounds, enzymes, and genetic resources with potential applications in crop protection, soil health, and plant biotechnology.

Ocean microbes drive the planet's major chemical cycles and can break down pollutants, and scientists are mapping these microbial communities globally to unlock their potential for cleaning up contaminated coastlines and developing new biotechnologies.
Marine microbes account for the majority of ocean biomass and drive most of Earth's key biogeochemical cycles, including those that regulate global climate.
Decades of industrialization and urbanization have caused widespread ocean contamination, with pollutants accumulating especially in coastal sediments and posing documented risks to marine ecosystems and human health.
Effective microbial breakdown of pollutants depends on syntrophic (cooperative) interactions between different microbial species, meaning community collaboration—not single organisms—is the key to bioremediation.
