Cyanobacteria's Resilience: Metabolic Shifts During Extended Nutrient Deprivation
When *Synechocystis* sp. CCNM 2501 faces 30 days of starvation, its response depends entirely on which nutrient is missing. Nitrogen deprivation drives progressive chlorosis and a final collapse of carotenoids. Phosphorus deprivation triggers an opposite, protective surge. These are not identical stress responses. They are distinct metabolic strategies. Understanding this distinction is essential for predicting bloom persistence in eutrophic waters. Our related work on *Gymnodinium catenatum* similarly explores how nutrient shifts reshape bloom dynamics at the proteome level.
Nitrogen Fixation Linked to Ocean Conditions in Northern Australia
Along Australia's northern coast, Trichodesmium blooms paint the surface in visible slicks, a signal of active nitrogen fixation. During a 1999 cruise from Townsville to Broome, we mapped these diazotrophs alongside picophytoplankton, linking their distribution to distinct water masses identified through cluster analysis. Where Trichodesmium thrived, it drove up to 25% of primary production and dominated surface biomass.
