This also applies to the smallest colorless eukaryotes in planktonic systems, the heterotrophic flagellates, which are important agents in bacterial mortality through grazing. The use of extensive sampling datasets and high-throughput sequencing tools allows to identify the dominant species and better define their ecological relevance in the marine environment. In particular, we focus here in two model groups that represent contrasted ecological strategies in terms of growth and grazing dynamics and oceanic distribution. One of these two groups still remains uncultured, so Single Cell Genomics is the only way to access to its genome content, which can then be used to analyze gene expression in natural communities. Opening the black box of microbial functional guilds is a necessity to really understand ecosystemic processes
