PCC to phosphate starvation by glycolipid accumulation and membrane lipid remodeling, Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, . The response of the picoplanktonic marine cyanobacterium Synechococcus species WH to phosphate starvation involves a protein homologous to the periplasmic phosphate-binding protein of.

Abstract. Oxygenic photoautotrophs of the genera Synechococcus and Prochlorococcus contribute significantly to primary production and are now widely accepted as the most abundant members of the picophytoplankton in the world's oceans. Since they represent one of the few cultured and representative groups of marine microorganisms, study of their physiology and biochemistry has progressed. The Journal of Phycology was founded in by the Phycological Society of America. All aspects of basic and applied research on algae are included to provide a common medium for the ecologist, physiologist, cell biologist, molecular biologist, morphologist, oceanographer, taxonomist, geneticist, and biochemist. The Journal also welcomes research that emphasizes algal interactions with other.

Phosphate uptake kinetics of Synechococcus sp. WH and Thalassiosira weissflogii were studied in axenic batch culture. Phosphate-replete Synechococcus sp. WH cells have a lower affinity for inorganic phosphate (Pi) (K s = 67 μmol l −1) than Pi-starved cells (K s = μmol l −1). The K s of Pi-starved cells increased ∼5-fold (K s = 14–20 μmol l −1) following. This further points to the critical need tocontinue developing genotypic- or cell-specific tools to assess the response of the picophytoplankton community to large-scale changes in nutrient conditions in the oceans.

Cyanobacteria, such as Synechococcus sp. PCC (Syn), are promising chassis strains for “green” biotechnological applications as they can be grown in seawater using oxygenic photosynthesis to fix carbon dioxide into biomass.

Their other major nutritional requirements for efficient growth are sources of nitrogen (N) and phosphorus (P). Prochlorococcus and Synechococcus, which numerically dominate vast oceanic areas, are the two most abundant oxygenic phototrophs on gh they require solar energy for photosynthesis, excess light and associated high UV radiations can induce high levels of oxidative stress that may have deleterious effects on their growth and productivity.
