Description:
This PhD project investigates the impact of Fe limitation i) on heme b abundance in phytoplankton and marine particulate matter, and ii) on the production, utilization and degradation processes of heme b by field work and laboratory experiments. The main research questions driving this work are 1) Can heme b be used as a proxy of Fe limitation in field phytoplankton populations? 2) Is phytoplankton able to regulate their heme b pool to reduce Fe requirements under Fe limitation? 3) Does heme b regulation originate from a modification in the gene expression of proteins involved in its cycling?
