Major research topics

  • Analysis of marine eukaryotic communities using metabarcoding (nuclear 18S rRNA, plastid 16S rRNA genes).
  • Diversity and oceanic distribution of marine phytoplankton, in particular green algae and pelagophytes.
  • Polar ohytoplankton communities and their adaptation to the long winter polar night.
  • Development of databases for the analysis of eukaryotic metabarcodes: PR2, pr2-primers and metaPR2 (in progress)

We found no evidence of phago-mixotrophy in any M. polaris strain based on flow cytometric measurement of prey ingestion. In addition, in silico predictions reveal that members of the genus Micromonas lack a genetic signature of phagocytotic capacity..
