[Controlled laboratory study using model organisms Micromonas commoda RCC 299 and Ruegeria pomeroyi DSS-3] - Bacterial transcriptional response to picoeukaryote Micromonas commoda (Effects of Climate Change Variables on Microbial Autotroph-Heterotroph Carbon Flux)

However, direct influences of bacteria on phytoplankton physiology are poorly known. In this study, three marine bacteria (Ruegeria pomeroyi DSS-3, Stenotrophomonas sp.

SKA14, and Polaribacter dokdonensis MED152) were co-cultured with green alga Micromonas commoda, and the phytoplankter's transcriptome was studied by RNASeq. The presence of each bacterium invoked transcriptomic remodeling by M. commoda after 8 h in co-culture. Some aspects of the algal transcriptomic response were conserved across all three bacteria, while others were restricted to a single bacterium.
