Engineering Pseudomonas protegens Pf-5 for nitrogen fixation and its application to improve plant growth under nitrogen-deficient conditions
(2013-05-13)
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 ...
The role of heterocytes in the physiology and ecology of bloom-forming harmful cyanobacteria
(Elsevier Science, 2016-12)
Dolichospermum flos-aquae and Cylindrospermopsis raciborskii are two cyanobacteria species which cause harmful blooms around the world. Both these species share the capacity to fix atmospheric nitrogen in heterocytes (cell ...
New insights into soybean biological nitrogen fixation
(American Society of Agronomy, 2018-08)
Soybean biological N2 fixation (BNF) relationships with fertilizer N and yield response have been comprehensively reviewed in the scientific literature. However, the study of the N-gap between N uptake and N supplied by ...
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 ...
Arbuscular mycorrhiza mediated effects on growth, mineral nutrition and biological nitrogen fixation of Melilotus alba Med. in a subtropical grassland soil
(Elsevier Science, 2019-02)
Soil symbiotic microorganisms promote recruitment of legume forage species in grassland ecosystems by enhancing provision for nutrients. We studied the effects of arbuscular mycorrhizal fungi (AMF) on plant growth, mineral ...
Relative importance of biological nitrogen fixation and mineral uptake in high yielding soybean cultivars
(2017-09)
Backgrounds and aims: Soybean yield depends on total N uptake, N use efficiency, and harvest index. Nitrogen uptake relays on biological fixation (BNF) and soil absorption. Usually, BNF is considered a yield-related process. ...
Feasibility of lowering soybean planting density without compromising nitrogen fixation and yield
(American Society of Agronomy, 2014)
Adjusting soybean [Glycine max (L.) Merrill] density can be critical to reduce inter-plant competition for water, nutrients, and sunlight, and to increase intercepted radiation, photosynthesis, and biomass production. The ...
Major cereal crops benefit from biological nitrogen fixation when inoculated with the nitrogen-fixing bacterium Pseudomonas protegens Pf-5 X940
(2016)
A main goal of biological nitrogen fixation research has been to expand the nitrogen-fixing ability to major cereal crops. In this work, we demonstrate the
use of the efficient nitrogen-fixing rhizobacterium Pseudomonas ...
