Using an integrative holobiont approach combining microbiome profiling, host physiology, and metabolomics, we evaluated the response of the Antarctic macroalga Adenocystis utricularis to thermal stress (2 °C vs. 8 °C).
Using an integrative holobiont approach combining microbiome profiling, host physiology, and metabolomics, we evaluated the response of the Antarctic macroalga Adenocystis utricularis to thermal stress (2 °C vs. 8 °C). Warming caused transient reductions in microbial diversity, community restructuring, and shifts toward heterotrophic functions, accompanied by impaired photosynthesis and increased oxidative stress. Metabolomic changes and the detection of the herbicide acetochlor further revealed strong holobiont plasticity and anthropogenic influence in Antarctic coastal ecosystems.
