Rhizobia inoculation improves nutrient uptake and growth of lowland rice.
TLDR
The results indicate that certain strains of rhizobia can promote rice growth and yield, most likely through mechanisms that involve changes in growth physiology or root morphology rather than BNF. Expand
Rhizobial Inoculation Influences Seedling Vigor and Yield of Rice
TLDR
These studies indicate that certain strains of nonphotosynthetic diazotrophs, including rhizobia, can promote growth and vigor of rice seedlings, and this benefit of early seedling development can carryover to significantly increased grain yield at maturity. Expand

TLDR
Replicated methanogenic bioreactor communities with two different community structures were established, and it is demonstrated that the more stable LS communities were less functionally stable than the HS communities. Expand
Short root mutant of Lotus japonicus with a dramatically altered symbiotic phenotype.
TLDR
Observations implicate a role for the Har1 locus in both symbiotic and non-symbiotic development of L. japonicus, and suggest that regulatory processes controlling nodule organogenesis and nodule number are integrated in an overall mechanism governing root growth and development. Expand
Natural endophytic association between Rhizobium leguminosarum bv. trifolii and rice roots and assessment of its potential to promote rice growth
For over 7 centuries, production of rice (Oryza sativa L.) in Egypt has benefited from rotation with Egyptian berseem clover (Trifolium alexandrinum). The nitrogen supplied by this rotation replacesExpand
A New Species of Devosia That Forms a Unique Nitrogen-Fixing Root-Nodule Symbiosis with the Aquatic Legume Neptunia natans (L.f.) Druce
TLDR
Sequence analysis showed that this newly described Neptunia-nodulating Devosia species may have acquired these symbiotic genes by horizontal transfer from Rhizobium tropici, suggesting that this new species may be able to acquire these symbiotically-induced nitrogenfixing genes through horizontal transfer. Expand
The beneficial plant growth-promoting association of Rhizobium leguminosarum bv. trifolii with rice roots
his paper summarizes a multinational collaborative project to search for natural, intimate associations between rhizobia and rice (Oryza sativa L.), assess their impact on plant growth, and exploitExpand
Parallel Processing of Substrate Correlates with Greater Functional Stability in Methanogenic Bioreactor Communities Perturbed by Glucose
TLDR
This hypothesis was tested for microbial community function using two quadruplicate sets of methanogenic communities, each set having substantially different populations, and indicated that the communities with predominantly parallel substrate processing were functionally more stable in response to the perturbation than the Communities with predominantly serial substrate processing. Expand
Coexistence of predominantly nonculturable rhizobia with diverse, endophytic bacterial taxa within nodules of wild legumes.
TLDR
Despite the inability to culture rhizobial endosymbionts from within the nodules using standard culture media, a direct 16S rRNA gene PCR analysis revealed that most of these nodules contained rhizobia as the predominant population. Expand
Ascending Migration of Endophytic Rhizobia, from Roots to Leaves, inside Rice Plants and Assessment of Benefits to Rice Growth Physiology
TLDR
The results indicate that this endophytic plant-bacterium association is far more inclusive, invasive, and dynamic than previously thought, including dissemination in both below-ground and above-ground tissues and enhancement of growth physiology by several rhizobial species, therefore heightening its interest and potential value as a biofertilizer strategy for sustainable agriculture.
