Glycogen synthesis is a required component of the nitrogen stress response in Synechococcus elongatus PCC 7942 (2013, background): “The response of non-diazotrophic cyanobacteria to nitrogen deprivation has been extensively studied in Synechococcus elongatus PCC 7942 [3,4].”
NOSTOC (CYANOPHYCEAE) GOES NUDE: EXTRACELLULAR POLYSACCHARIDES SERVE AS A SINK FOR REDUCING POWER UNDER UNBALANCED C/N METABOLISM 1 (2004, background): “The phenomena described provide the basis and tools for the study of nitrogen control of carbon metabolic processes in cyanobacteria, which so far has been limited to intracellular polysaccharides (Herrero et al. 2001).”
Phylogeny of the bacterial superfamily of Crp-Fnr transcription regulators: exploiting the metabolic spectrum by controlling alternative gene programs. (2003, background): “The repressive e¡ect of ammonium on both nitrate and dinitrogen assimilation depends on a functional glutamine synthetase, which suggests a common mechanism operative for the di¡erent sources of nitrogen [107].”
The role of functional traits and trade-offs in structuring phytoplankton communities: scaling from cellular to ecosystem level. (2007, background): “In agreement with this reasoning, cyanobacteria, the earliest photoautotrophs, evolved under anoxic conditions (Anbar & Knoll 2002; Hedges et al. 2004), also have a strong preference for ammonium over nitrate (Herrero et al. 2001).”
