About the research project

Microbiome bacteria living on or near phytoplankton cells – in the phycosphere - are critical for phytoplankton health and maintaining primary production in the ocean.  Preliminary research on these bacteria indicate that they possess a range of surprising adaptations compared to their free-living marine relatives. Examples include biosynthesis of novel signalling molecules, growth stimulators and phytohormones, and apparent loss of entire pathways normally considered to be core metabolic functions.  This project aims to combine flow cytometry with novel culture and culture independent approaches to capture, sequence and assemble complete genomes of phytoplankton microbiome bacteria from natural phytplankton blooms. Using comparative genomics approaches and curated microbiome databases, the project aims to identify genomic and functional adaptation of bacteria to phycosphere micro-environments that are critical to their interaction with phytoplankton host cells, and to primary production in the ocean.
