Nitrogen is a quantitatively important bioelement which is incorporated into the biosphere through assimilatory processes carried out by microorganisms and plants. Numerous nitrogencontaining compounds can be used by different organisms as sources of nitrogen. These include, for instance, inorganic ions like nitrate or ammonium and simple organic compounds like urea, amino acids, and some nitrogen-containing bases. Additionally, many bacteria are capable of fixing N 2. Nitrogen control is a… Expand
Nitrogen assimilation and nitrogen control in cyanobacteria.
TLDR
The expression of many nitrogen assimilation genes is subjected to regulation being activated by the nitrogen-control transcription factor NtcA, which is autoregulatory and whose activity appears to be influenced by 2-oxoglutarate and the signal transduction protein P(II). Expand
Genetic responses to carbon and nitrogen availability in Anabaena.
TLDR
The mechanisms of assimilation of ammonium, nitrate, urea and N2 , the latter involving heterocyst differentiation, are summarized and aspects of CO2 assimilation that involves a carbon concentration mechanism are described. Expand
Effect of Nitrogen Source on Cyanophycin Synthesis in Synechocystis sp. Strain PCC 6308
TLDR
Nitrogen is incorporated into cyanophycin at different rates and to different extents, depending on the source of nitrogen (ammonium or nitrate) and whether the cells are first starved for nitrogen. Expand
Nitrogen Fixation Outside and Inside Plant Tissues
Nitrogen is one of the most important elements in biological systems, comprising the main building blocks of nucleic acids, enzymes and proteins among its multiple functions. In nature, it existsExpand

Cyanobacteria are photosynthetic prokaryotes that play a crucial role in the Earth's nitrogen and carbon cycles. Nitrogen availability is one of the most important factors in cyanobacterial growth.Expand
Heterocyst Differentiation and Nitrogen Fixation in Cyanobacteria
Cyanobacteria face the difficult problem of fixing nitrogen while generating oxygen. Some solve this problem by storing carbohydrate during the day and using the stored material to fuel nitrogenExpand
Nitrogen Fixation and Hydrogen Metabolism in Cyanobacteria
TLDR
A likely better strategy is to exploit the use of radiant solar energy by the photosynthetic electron transport system to enhance the rates of H2 formation and so improve the chances of utilizing cyanobacteria as a source for the generation of clean energy. Expand
Nitrogen metabolism in cyanobacteria: metabolic and molecular control, growth consequences and biotechnological applications
TLDR
Why a better understanding of the mechanisms involved in the partitioning of carbon and nitrogen towards growth or storage would increase the biotechnological potential of these organisms is highlighted. Expand

Abstract Nitrogen is one of the important components for algae and is available in nature in various redox states. Regulation in transport and assimilation of forms or compounds varies considerablyExpand
Regulation of ammonium assimilation in cyanobacteria
TLDR
Regulation of the GS-GOGAT pathway is essential for the carbon/nitrogen balance in cyanobacteria and the transcription factor NtcA increases the expression of ammonium permease, ICDH, GSI and GSIII under conditions of nitrogen limitation. Expand

TLDR
Examination of GlnR‐ and TnrA‐regulated gene expression suggests that these proteins allow the cell to adapt to growth during nitrogen‐limited conditions, and may reflect the fact that the catabolism of amino acids produced by proteolysis during sporulation and germination provides the cell with substrates for energy production and macromolecular synthesis.
