The boost of the greenhouse gases (GHGs, largely carbon dioxide–CO 2) emissions owing
to anthropogenic activity is one of the biggest global threats. Bio-CO 2 emission reduction …

ABSTRACT Carbon/nitrogen (C/N) balance sensing is a key requirement for the
maintenance of cellular homeostasis. Therefore, cyanobacteria have evolved a …

Microbial communities mediating anaerobic ammonium oxidation (anammox) represent one
of the most energy-efficient environmental biotechnologies for nitrogen removal from …

Tricarboxylic acid cycle (TCA cycle) plays an important role for aerobic growth of
heterotrophic bacteria. Theoretically, eliminating TCA cycle would decrease carbon …

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 …

Tremendous chemical diversity is the hallmark of plants and is supported by highly complex
biochemical machinery. Plant metabolic enzymes originated and were transferred from …

The monophyletic group of embryophytes (land plants) stands out among photosynthetic
eukaryotes: they are the sole constituents of the macroscopic flora on land. In their entirety …

The metabolite 2-oxoglutarate (also known as α-ketoglutarate, 2-ketoglutaric acid, or
oxoglutaric acid) lies at the intersection between the carbon and nitrogen metabolic …

Cyanobacteria are photosynthetic prokaryotes showing great promise as biocatalysts for the
direct conversion of CO 2 into fuels, chemicals, and other value-added products. Introduction …

Cyanobacteria were responsible for the oxygenation of the ancient atmosphere; however,
the evolution of this phylum is enigmatic, as relatives have not been characterized. Here we …
