| Project Title: | Seasonal Signatures in Asparagopsis taxiformis (Rhodophyta) Holobiont: Linking Epiphytic Microbial Communities, Metabolite Profiles, and Bioactivity |
| Project Summary: | The epiphytic microbiome of seaweed plays a central role in host physiology, defense, and adaptation. This host–microbe association, known as the holobiont, is shaped by environmental factors such as temperature and seasonality, which also influence bioactive compound production in both marine and terrestrial organisms. Asparagopsis taxiformis is a red macroalga with cosmopolitan distribution, high invasive potential, and growing biotechnological interest. We conducted a two-year, bi-monthly survey at two Israeli Mediterranean sites to examine seasonal links between its epiphytic microbiome and metabolome. Seawater temperature emerged as the primary driver of variation in both microbial composition and metabolite profiles, with host lineage and site showing secondary effects. Warmer periods correlated with higher bacterial diversity, elevated brominated metabolites, and stronger antibacterial activity. These patterns suggest that A. taxiformis adjusts its chemical output in response to seasonal microbial dynamics and provide a framework for optimizing bioactive compound production under controlled cultivation. |
