Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao

PLANTS, PEOPLE, PLANET, EarlyView.
Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...

Herbicide toxicity to Nitrospirillum amazonense: assessing bacterial survival and microbial functionality

Pest Management Science, EarlyView.
Herbicides elicit a spectrum of responses in Nitrospirillum amazonense, ranging from the stimulation of metabolic functions (biological nitrogen fixation, IAA production) to significant growth inhibition and acute toxicity. Abstract BACKGROUND Herbicides can exert significant toxicity on nontarget organisms, including plant growth‐promoting bacteria ...

Nitrogenase and nitrogenase reductase associate and dissociate with each catalytic cycle. [PDF]

Proceedings of the National Academy of Sciences, 1978
Nitrogenase and nitrogenase reductase dissociate after each electron is transferred between them, as shown by the occurrence of a lag phase approximately as long as the average turnover time of nitrogenase before hydrogen evolution occurs. Because nitrogenase was present in the reaction mixture in large excess over nitrogenase reductase, the electrons ...

State of the art in eukaryotic nitrogenase engineering

FEMS Microbiology Letters, 2017
Improving the ability of plants and plant-associated organisms to fix and assimilate atmospheric nitrogen has inspired plant biotechnologists for decades, not only to alleviate negative effects on nature from increased use and availability of reactive ...

Structural analysis of the NifL‐NifA complex reveals the molecular basis of anti‐activation of nitrogen fixation gene expression in Azotobacter vinelandii

The FEBS Journal, EarlyView.
Using cryo‐EM combined with biochemical and genetic approaches, we mapped the interaction surface between NifL and NifA to gain insights into the regulation of nitrogen fixation genes in A. vinelandii. Our findings suggest that NifL, a homolog of histidine kinases lacking phosphorylation activity, evolved to act as a steric block of NifA activity ...

Biosynthesis of the nitrogenase active-site cofactor precursor NifB-co in Saccharomyces cerevisiae

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Nitrogen is a constituent of many essential biomolecules and plentiful on earth as inert N2 gas. For its assimilation by eukaryotes, N2 must be converted to a metabolically tractable form such as ammonium.

Editing a gibberellin receptor gene improves yield and nitrogen fixation in soybean

Journal of Integrative Plant Biology, EarlyView.
Knockout of the soybean gibberellin receptor gene GmGID1‐2 reduced plant height; strengthened stems; increased the number of branches, nodes, pods, and seeds; and improved yield, seed oil content and nitrogen fixation. ABSTRACT Soybean is an important source of oil, protein, and feed. However, its yield is far below that of major cereal crops.

Establishing a Thermodynamic Landscape for the Active Site of Mo-Dependent Nitrogenase.

Journal of the American Chemical Society, 2019
Nitrogenase enzymes are the only biological catalysts able to convert N2 to NH3. Molybdenum-dependent nitrogenase con-sists of two proteins and three metallocofactors that sequentially shuttle eight electrons between three distinct metallocofac-tors ...

CPOP1 is a key enzyme required for nodule microenvironment control and successful symbiotic nitrogen fixation in Lotus japonicus

Journal of Integrative Plant Biology, EarlyView.
The enzyme coproporphyrinogen III oxidase plastid related 1 (CPOP1) creates a low‐oxygen nodule environment for nitrogen fixation within nodules of Lotus japonicus. CPOP1 makes heme, which helps control oxygen, and acts in infected cells; its knockout raises oxygen levels, suppresses nitrogen‐fixing enzyme activity, and halts nitrogen fixation ...

Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics

New Phytologist, EarlyView.
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their
