A recent15N dilution/N balance study confirmed that certain sugar cane varieties are capable of obtaining large contributions of nitrogen from plant-associated N2 fixation. It was estimated that up to 60 to 80% of plant N could be derived from this source, and under good conditions of water and mineral nutrient supply, it may be possible to dispense with N fertilization of these varieties altogether. The recently discovered bacterium,Acetobacter diazotrophicus, apparently responsible for this… 
Biological nitrogen fixation associated with sugar cane and rice: Contributions and prospects for improvement
Abstract15N isotope and N balance studies performed over the last few years have shown that several Brazilian varieties of sugarcane are capable of obtaining over 60% of their nitrogen (<150 kg N
Nitrogen Fixing Endophytes in Forest Trees
Direct evidence of N2 fixation and incorporation by native endophytes has been demonstrated in poplar using labelling with the stable nitrogen isotope 15N2, and suggestions are provided for research efforts that can take advantage of this new knowledge with the goal of reducing the use of chemical fertilizer in agriculture and forestry.
Nitrogen-Fixation by Endophytic Bacteria in Agricultural Crops: Recent Advances
The mechanisms of biological nitrogen fixation and methods to quantify the fixed nitrogen are discussed along with reviewing recent studies focused on evaluating the role of endophytic diazotrophic bacteria in promoting plant growth in both native and nonnative crop hosts.
Endophytic N-Fixation: Controversy and a Path Forward
This review describes the arguments and summarizes the data in support of the significance of endophytic N-fixation, and proposes research directions with the aim of optimizing endophyte-host interactions for reduced reliance on chemical fertilizers.
Nitrogen fixation during decomposition of sugarcane (Saccharum officinarum) is an important contribution to nutrient supply in traditional dryland agricultural systems of Hawai'i
It is found that significant N may be introduced into natural cropping systems through mulching practices and that small changes in practices greatly alter the total inputs.
Can a N2-fixing Gluconacetobacter diazotrophicus association with sugarcane be achieved?
It is concluded that a N-2-fixing sugarcane - G. diazotrophicus association is not easily achievable, being primarily limited by a lack of infection.
Plant Growth-Promoting Effects of Diazotrophs in the Rhizosphere
It is now clear that associative diazotrophs exert their positive effects on plant growth directly or indirectly through (a combination of) different mechanisms, and further elucidation of the different mechanisms involved will help to make associative Diazotrophic bacteria a valuable partner in future agriculture.
Complete Genome Sequence of Enterobacter roggenkampii ED5, a Nitrogen Fixing Plant Growth Promoting Endophytic Bacterium With Biocontrol and Stress Tolerance Properties, Isolated From Sugarcane Root
It is proposed that identification of predicted genes and metabolic pathways might describe this strain an eco-friendly bioresource to promote sugarcane growth by several mechanisms of actions under multi-stresses.
Endophytic nitrogen fixation - a possible 'hidden' source of nitrogen for lodgepole pine trees growing at unreclaimed gravel mining sites.
The results support the possibility that pine trees associate with nitrogen-fixing bacteria, capable of endophytic colonization, to survive at unreclaimed gravel mining pits and this association could potentially be utilized for effective reclamation of highly disturbed sites in a sustainable manner.


Nitrogen fixation associated with sugarcane.
The aim was to determine whether appreciable nitrogen fixation takes place in association with cane grown in South Africa and to define optimum conditions for this fixation.
Ammonium inhibition of nitrogenase activity in Herbaspirillum seropedicae
The effect of oxygen, ammonium ion, and amino acids on nitrogenase activity in the root-associated N2-fixing bacterium Herbaspirillum seropedicae was investigated and there is no clear evidence that ADP-ribosylation of the dinitrogenase reductase is involved in the ammonium inhibition of H. seropedICae.
Acetobacter diazotrophicus sp. nov., a Nitrogen-Fixing Acetic Acid Bacterium Associated with Sugarcane
Results of deoxyribon nucleic acid (DNA)-ribosomal ribonucleic acid and DNA-DNA hybridizations revealed that nitrogen-fixing bacteria isolated from roots and stems of sugarcane belong to a new species in the genus Acetobacter, for which the name AcetOBacter diazotrophicus sp.
Morphological characteristics, reserve substance formation, and ecological aspects of the distribution of Beijerinckia are discussed. Beijerinckia cells are single or bicellular due to cross wall
Interactions of Glomus clarum with Acetobacter diazotrophicus in infection of sweet potato (Ipomoea batatas), sugarcane (Saccharum spp.), and sweet sorghum (Sorghum vulgare)
The sugarcane seedlings showed the greatest infection of aerial parts after inoculation with VAM spores containing the diazotrophs, and this treatment also increased VAM colonization and the numbers of spores formed within roots.
