Systemic regulation of soybean nodulation and nitrogen fixation by nitrogen via isoflavones

Frontiers in Plant Science, 2022
Nitrogen (N) inhibits soybean (Glycine max L.) nodulation and N2 fixation. Isoflavones secreted by soybean roots can stimulate signal transduction for symbiotic nodules, thus playing a key role in root nodule development and N2 fixation. The relationship

Upstream regulation of yeast TOR complexes [PDF]

, 2015
Nitrogen is an essential component of living organism. Protein synthesis and biosynthesis of nitrogen containing molecules essential for growth, such as amino acids and NAD, strictly depend on the availability of the nitrogen source. Limiting amount of

Bacterial nitrogen-related phosphotransferase systems: new insights into diverse roles in virulence, physiology, and central metabolism

Journal of Bacteriology
Nitrogen-related phosphotransferase (PTSNtr) systems are highly conserved and widely distributed in proteobacteria. These systems are thought to enable bacteria to sense and respond to changes in cellular carbon and nitrogen availability.

Development of an auto-inducible expression system by nitrogen sources switching based on the nitrogen catabolite repression regulation

Microbial Cell Factories, 2022
Background The construction of protein expression systems is mainly focused on carbon catabolite repression and quorum-sensing systems. However, each of these regulatory modes has an inherent flaw, which is difficult to overcome.

PipY, a Member of the Conserved COG0325 Family of PLP-Binding Proteins, Expands the Cyanobacterial Nitrogen Regulatory Network

Frontiers in Microbiology, 2017
Synechococcus elongatus PCC 7942 is a paradigmatic model organism for nitrogen regulation in cyanobacteria. Expression of genes involved in nitrogen assimilation is positively regulated by the 2-oxoglutarate receptor and global transcriptional regulator ...

Time-resolved multi-omics analysis reveals the role of nutrient stress-induced resource reallocation for TAG accumulation in oleaginous fungus Mortierella alpina

Biotechnology for Biofuels, 2020
Background Global resource reallocation is an established critical strategy through which organisms deal with environmental stress. The regulation of intracellular lipid storage or utilization is one of the most important strategies for maintaining ...

Abundances of Iron-Binding Photosynthetic and Nitrogen-Fixing Proteins of Trichodesmium Both in Culture and In Situ from the North Atlantic [PDF]

, 2012
Marine cyanobacteria of the genus Trichodesmium occur throughout the oligotrophic tropical and subtropical oceans, where they can dominate the diazotrophic community in regions with high inputs of the trace metal iron (Fe).

Regulation of sporulation in the yeast Saccharomyces cerevisiae. [PDF]

, 2010
Sporulation of the budding yeast Saccharomyces cerevisiae — equivalent to gametogenesis in higher organisms, is a complex differentiation program induced by starvation of cells for nitrogen and carbon.
