Low oxygen levels contribute to improve photohydrogen production in mixotrophic non‑stressed Chlamydomonas cultures
(BioMed Central, 2015)
Background: Currently, hydrogen fuel is derived mainly from fossil fuels, but there is an increasing interest in clean
and sustainable technologies for hydrogen production. In this context, the ability of some photosynthetic ...
Arginine is a component of the ammonium- CYG56 signalling cascade that represses genes of the nitrogen assimilation pathway in Chlamydomonas reinhardtii
(Public Library of Science, 2018)
Nitrogen assimilation and metabolism are essential processes for all living organisms, yet
there is still much to be learnt on how they are regulated. The use of Chlamydomonas reinhardtii
as a model system has been ...
Characterization of a Mutant Deficient for Ammonium and Nitric Oxide Signalling in the Model System Chlamydomonas reinhardtii
(Public Library of Science, 2016)
The ubiquitous signalling molecule Nitric Oxide (NO) is characterized not only by the variety
of organisms in which it has been described, but also by the wealth of biological processes
that it regulates. In contrast to ...
From the Eukaryotic Molybdenum Cofactor Biosynthesis to the Moonlighting Enzyme mARC
(MDPI, 2018)
All eukaryotic molybdenum (Mo) enzymes contain in their active site a Mo Cofactor (Moco), which is formed by a tricyclic pyranopterin with a dithiolene chelating the Mo atom. Here, the eukaryotic Moco biosynthetic pathway ...
Role of Nitrate Reductase in NO Production in Photosynthetic Eukaryotes
(MDPI, 2019)
Nitric oxide is a gaseous secondary messenger that is critical for proper cell signaling and plant survival when exposed to stress. Nitric oxide (NO) synthesis in plants, under standard phototrophic oxygenic conditions, ...
Algae-Bacteria Consortia as a Strategy to Enhance H2 Production
(MDPI, 2020)
Biological hydrogen production by microalgae is a potential sustainable, renewable and clean source of energy. However, many barriers limiting photohydrogen production in these microorganisms remain unsolved. In order to ...
Identification of the MAPK Cascade and its Relationship with Nitrogen Metabolism in the Green Alga Chlamydomonasreinhardtii
(MDPI, 2020)
The mitogen activated protein kinases (MAPKs) form part of a signaling cascade through phosphorylation reactions conserved in all eukaryotic organisms. The MAPK cascades are mainly composed by threeproteins, MAPKKKs, MAPKKs ...
Chlamydomonas reinhardtii, an Algal Model in the Nitrogen Cycle
(MDPI, 2020)
Nitrogen (N) is an essential constituent of all living organisms and the main limiting macronutrient. Even when dinitrogen gas is the most abundant form of N, it can only be used by fixing bacteria but is inaccessible to ...
Understanding nitrate assimilation and its regulation in microalgae
(Frontiers, 2015)
Nitrate assimilation is a key process for nitrogen (N) acquisition in green microalgae. Among Chlorophyte algae, Chlamydomonas reinhardtii has resulted to be a good model system to unravel important facts of this process, ...
NRT2.4 and NRT2.5 Are Two Half-Size Transporters from the Chlamydomonas NRT2 Family
(MDPI, 2016)
The NRT2 transporters mediate High Affinity Nitrate/NitriteTransport (HAN/NiT),
which are essential for nitrogen acquisition from these inorganic forms. The NRT2 proteins are
encoded by a multigene family in plants, and ...
