Salinity Stress and the Holobiont: Investigating Algal-Bacterial Interactions in Chrysochromulina tobinii

Summary

This research investigates how salinity stress, an escalating environmental concern due to climate change, impacts the symbiotic relationship (holobiont) between algae (*Chrysochromulina tobinii*) and its associated bacteria, which are vital for ecological balance and have economic potential in areas like biofuels. The study employed metagenomic and metatranscriptomic analyses to detail shifts in holobiont community structure and gene expression under various salinity levels. Findings revealed specific bacterial genera dominating in holobiont samples, with their abundance dynamically changing with salinity, thereby providing crucial insights into survival mechanisms against osmotic stress.
