Explaining coexistence of nitrogen fixing and non-fixing rhizobia in legume-rhizobia mutualism using mathematical modeling
(Elsevier, 2017-07-12)
In the mutualism established between legumes and soil bacteria known as rhizobia, bacteria from soil infect plants roots and reproduce inside root nodules where they fix atmospheric N2 for plant nutrition, receiving ...
High-quality forage production under salinity by using a salt-tolerant AtNXH1-expressing transgenic alfalfa combined with a natural stress-resistant nitrogen-fixing bacterium
(Elsevier Science, 2018-06)
Alfalfa, usually known as the “Queen of Forages”, is the main source of vegetable protein to meat and milk production systems worldwide. This legume is extremely rich in proteins due to its highly efficient symbiotic ...
Deferred control of ammonium cross-feeding in a N2-fixing bacterium-microalga artificial consortium
(Springer, 2021-04)
There is an increasing interest in the use of N2-fixing bacteria for the sustainable biofertilization of crops. Genetically-optimized bacteria for ammonium release have an improved biofertilization capacity. Some of these ...
Engineering Pseudomonas protegens Pf-5 for Nitrogen Fixation and its Application to Improve Plant Growth under Nitrogen-Deficient Conditions
(Public Library of Science, 2013-05)
Nitrogen is the second most critical factor for crop production after water. In this study, the beneficial rhizobacterium Pseudomonas protegens Pf-5 was genetically modified to fix nitrogen using the genes encoding the ...
Test of Host Sanction Hypothesis in Soybean Plants Co-inoculated with Nitrogen Fixing and Non-fixing Bradyrhizobium japonicum
(ScienceDomain International, 2015-01)
Aims: We tested the proposed mechanism for potential sanctions, that the plant would reduce viability of non-fixing rhizobia inside nodules, performing viable Bradyrhizobium japonicum counts from co-occupied and single-occupied ...
Symbiotic nitrogen fixation of Dimorphandra macrostachya in forests of Venezuelan Guayana HighlandFijación simbiótica de nitrógeno en Dimorphandra macrostachya de los bosques del altiplano de la Guayana Venezolana

Cyanobacterial biological nitrogen fixation as a sustainable nitrogen fertilizer for the production of microalgal oil
(Elsevier Science London, 2015-11)
Oleaginous microalgae have a great potential as a feedstock for biodiesel and other biofuels. However, the current cost of producing biofuels from microalgae biomass is still high to envision massive and profitable ...
The elusive quantification of nitrogen fixation in xeric shrubs: The case of Adesmia volckmanni, a Patagonian leguminous shrub
(Academic Press Ltd - Elsevier Science Ltd, 2014-12)
The comparison of 15N natural abundance (δ15N) between fixing and non-fixing reference species, is the most feasible method for nitrogen fixation studies in xeric shrubs. However, it assumes that both species use the same ...
Compatibility between legumes and rhizobia for the establishment of a successful nitrogen-fixing symbiosis
(MDPI, 2018-03)
The root nodule symbiosis established between legumes and rhizobia is an exquisite biological interaction responsible for fixing a significant amount of nitrogen in terrestrial ecosystems. The success of this interaction ...
Evaluation of inoculation with asymbiotic nitrogen-fixing microorganisms isolated from rhizosphere of Pinus patula in ColombiaEvaluación de la inoculación con microorganismos fijadores de nitrógeno asimbióticos aislados de la rizósfera de Pinus patula en Colombia
