The role of microbial interactions on rhizobial fitness
Frontiers in Plant Science, 2023 Rhizobia are soil bacteria that can establish a nitrogen-fixing symbiosis with legume plants. As horizontally transmitted symbionts, the life cycle of rhizobia includes a free-living phase in the soil and a plant-associated symbiotic phase.

Herbicides effects on symbiotic nitrogen-fixing bacteria [PDF]
Journal of Central European Agriculture, 2022 Rhizobia are an important component of sustainable agricultural production. In symbiosis with legumes, they provide adequate amounts of nitrogen for their growth and leave nitrogen in the soil for crops that follow in the rotation.

Promoter prediction in the rhizobia [PDF]
Microbiology, 2006 The ability to recognize and predict non-σ54promoters in the alphaproteobacteria is not well developed. In this study, 25 experimentally verifiedSinorhizobium melilotipromoter sequences were compiled and used to predict the location of other related promoters in theS. melilotigenome.

Agronomie, 2001 Rhizobia are the bacteria that form nitrogen-fixing symbioses with legumes. Based on their characterisation by polyphasic taxonomy, their classification has undergone great changes in recent years. The current six rhizobium genera and 28 recognised species are reviewed here.

Auxotrophy in rhizobia revisited [PDF]
Indian Journal of Microbiology, 2007 Among the various types of mutations studied in rhizobia, the auxotrophic mutations (which confer on the mutants the inability to synthesize certain essential substances such as amino acids, vitamins and nucleic acids), are the most favoured ones as these can be used as suitable markers for genetic analysis.

H2S Crosstalk in Rhizobia Modulates Essential Nutrient Allocation and Transport in Soybean
Agronomy, 2023 Hydrogen sulfide (H2S), a novel gas signaling molecule, plays a crucial role in plant growth and stress response. However, little attention has been devoted to the regulation of H2S on nutrient transport and utilization in legume–rhizobia symbiosis ...
