About the research project

Like humans, microalgae and other plankton rely on bacteria – their unique microbiomes. Metabolically active microbiomes are essential for primary production in the ocean and contribute to development of harmful algal blooms (HABs). Imbalanced or depleted microbiomes can substantially alter the way plankton respond to environmental change, lead to disease and/or death of the host plankton cell, or modify production of marine biotoxins that poison humans of marine animals. Plankton cell microbiomes differ substantially from the background seawater microbial community, but how they are selectively recruited, and the principles governing community assembly remain unknown. This project aims to examine key parameters governing recruitment and development of phylogenetic and functional diversity of phytoplankton microbiomes using synthetic microbiome models, microbiome recruitment experiments, and microbial community profiling using high-throughput DNA sequencing.
