MM007:
Phytoplankton-Bacteria Interactions - From Microscales to Ocean-scales


Session ID#: 27973

Session Description:
Interactions between phytoplankton and bacteria arguably represent the most important inter-organism association in aquatic environments. These relationships influence fundamental processes that include nutrient provision and regeneration, primary production, harmful blooms and biogeochemical cycling. Although typically studied over large spatiotemporal scales, emerging evidence indicates that this relationship is often governed by microscale interactions played out within the region immediately surrounding individual phytoplankton cells known as ‘the phycosphere.’ The exchange of metabolites and infochemicals at this interface governs phytoplankton-bacteria relationships, which span mutualism, commensalism antagonism, parasitism and competition. The importance of the phycosphere has been postulated for four decades, yet only recently have new technological and conceptual frameworks made it possible to start teasing apart the complex nature of this unique microbial habitat. In this session, we aim to provide a platform for researchers from diverse backgrounds to explore phytoplankton-bacteria interactions in the phycosphere and beyond, using model experimental systems, environmental data, modelling and new technologies.
