- Abstract:
- Plasma membrane electron transport is a ubiquitous process in eukaryotic organisms. However, the prevalence, physiological role and physiochemical consequences of eukaryotic phytoplankton plasma membrane electron transport are unknown. Cell surface reduction as a strategy for diatom trace metal acquisition has been documented but the precise mechanism needs to be determined. Moreover, reduction of Fe-chelates accounts for only a fraction of total constitutive capacity for plasma membrane electron transport. In this proposal we address the need for a thorough understanding of the cellular mechanisms that mediate and regulate constitutive plasma membrane reduction in diatoms and the relevance to trace metal acquisition. We will also establish to what extent diatom plasma membrane electron transport can contribute peroxide production in aquatic environments. The outcomes of this research will therefore significantly contribute to our understanding of how eukaryotic phytoplankton impact aquatic chemistry in the euphotic zone.
