Functional reconstitution of a bacterial CO2 concentrating mechanism in Escherichia coli
eLife, 2020 Many photosynthetic organisms employ a CO2 concentrating mechanism (CCM) to increase the rate of CO2 fixation via the Calvin cycle. CCMs catalyze ≈50% of global photosynthesis, yet it remains unclear which genes and proteins are required to produce this ...

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).

Litter Quality of Populus Species as Affected by Free-Air CO2 Enrichment and N-Fertilization [PDF]
, 2009 The effect of elevated CO2 and nitrogen fertilization on the molecular chemistry of litter of three Populus species and associated soil organic matter (SOM) was investigated by pyrolysis-gas chromatography/mass spectrometry.

White lupin (Lupinus albus L.) exposed to elevated atmospheric CO2 requires additional phosphorus for N2 fixation [PDF]
, 2022 Purpose: The steady rise of atmospheric CO2 concentrations enhances symbiotic N2 fixation and plant growth. However, it is largely unknown whether more P is required to enhance N2 fixation under elevated CO2.

Enhanced carbon dioxide conversion at ambient conditions via a pore enrichment effect
Nature Communications, 2020 Currently the cost of CO2 chemical fixation remains high because of harsh reaction conditions. Here, the authors report a covalent organic framework screened from 10994 candidates as the efficient CO2 fixation catalyst under ambient conditions based on ...

Time‐resolved transcriptome analysis of Scenedesmus obliquus HTB1 under 10% CO2 condition
Microbial Biotechnology, 2023 Certain microalgal species can grow under high CO2 concentrations providing potential for mitigating CO2 pollution in flue gas produced by power plants. Microalga Scenedesmus obliquus strain HTB1 was isolated from the Chesapeake Bay and grow rapidly in a

The impact of long-term elevated CO2 on C and N retention in stable SOM pools [PDF]
, 2008 Elevated atmospheric CO2 frequently increases plant production and concomitant soil C inputs, which may cause additional soil C sequestration. However, whether the increase in plant production and additional soil C sequestration under elevated CO2 can be

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.
