2. Monitoring the cellular phosphate status in bloom-forming cyanobacteria of the Baltic Sea
Abstract : In the Baltic Sea dense cyanobacterial blooms occur regularly during late summer. Since the dominant bloom-forming cyanobacteria, Nodularia spp. and Apanizomenon spp. are capable of fixing atmospheric dinitrogen, the macronutrient predominantly limiting their growth is phosphorus.

3. Phosphoinositides control insulin secretion through multiple routes
Abstract : Glucose-stimulated insulin secretion from pancreatic beta cells is the sequence of events that starts with glucose uptake and ends with the fusion of insulin granules with the plasma membrane through Ca2+-triggered exocytosis. Phosphoinositides are minor components of all cellular membranes, yet play fundamental roles as regulators of many cellular processes. READ MORE

4. Nutrient dynamics in the North Pacific subtropical gyre : phosphorus fluxes in the upper oligotrophic ocean
Abstract : In the contemporary North Pacific subtropical gyre (NPSG) the extant microbial community is based on prokaryotic cells with the cyanobacterium Prochlorococcus dominating the phototrophic component. The prevalence of dinitrogen (N2) fixing organisms, such as Trichodesmium spp. READ MORE
