Journal ArticleDOI
A new acid-tolerant nitrogen-fixing bacterium associated with sugarcane
TL;DR: A new genus and species are proposed and namedSaccharobacter nitrocaptans, which is an aerobic rod, motile by 1 to 3 lateral flagella, fixes N2 in semisolid media under air but not in liquid media except when a starter dose of N is added.
Journal ArticleDOI
Recent advances in BNF with non-legume plants
JoséI. Baldani,Leonardo Caruso,Vera Lúcia Divan Baldani,Silvia Regina Goi,Johanna Döbereiner +4 more
TL;DR: The ability to colonise the entire plant interior and locate themselves within niches protected from oxygen or other factors make obligate endophytes the most promising group of diazotrophs associated with graminaceous and other non-leguminous plants.
Book ChapterDOI
Biological nitrogen fixation associated with sugar cane and rice: Contributions and prospects for improvement
Robert M. Boddey,O. C. de Oliveira,Segundo Urquiaga,Veronica Massena Reis,F. L. de Olivares,Vera Lúcia Divan Baldani,Johanna Döbereiner +6 more
TL;DR: The sugarcane/endophytic diazotroph association is the first efficient N2-fixing system to be discovered associated with any member of the gramineae and should serve as a foundation for the improvement/development of similar N2 -fixing systems in wetland rice and other cereal crops.
Journal ArticleDOI
Host-plant specificity in the infection of cereals with Azospirillum spp
TL;DR: The specificity of the infection of maize, wheat and rice roots by N2-fixing Azospirillum spp was studied using pots with unsterilized soil and in two field experiments and results were partially obscured by the unexpectedly high proportion of streptomycin-resistant strains isolated from within the roots of uninoculated plants.
Journal ArticleDOI
Infection of sugar cane by the nitrogen-fixing bacterium Acetobacter diazotrophicus
Euan K. James,Veronica Massena Reis,Fábio Lopes Olivares,José Ivo Baldani,Johanna Döbereiner +4 more
TL;DR: In a series of experiments, aseptically-grown sugar cane plantlets were rooted in a liquid medium and inoculated with Acetobacter diazotrophicus, an acid-tolerant endophytic bacterium which grows best on a sucrose-rich medium.
