Dose-dependent transcriptional responses of marine prokaryotes to Fe-rich colloids of glacial and non-glacial origin in the Kerguelen region (Southern Ocean)

Carla Pereira-García, Urania Christakis, Rhea Thoppil…·Ingrid Obernosterer

This study examines how marine prokaryotes respond transcriptionally to Fe-rich colloids from glacial and non-glacial sources, revealing contrasting growth and metabolic responses.

TonB-dependent Transporters of Fe-petrobactin in Marinobacter nauticus and Southern Ocean bacteria

Sophie Nolivos, Rhea Thoppil, Florence Hakil…·R Grimaud

The paper identifies two TBDTs in Marinobacter nauticus that mediate Fe-petrobactin uptake, showing distinct regulatory mechanisms and evolutionary trajectories, and demonstrates Fe-petrobactin's role in stimulating prokaryotic growth in Southern Ocean communities.
