The association between legume plants and a group of alpha-proteobacteria, collectively known as rhizobia, allows the reduction of atmospheric nitrogen into ammonia in specialized organs called root nodules.

Abiotic stresses constraint yield and turn agriculture production systems fragile; in addition, persisting climate change intensify the frequency, degree, and resultant damage. Plants have evolved complex mechanisms to tolerate abiotic stresses caused by various environmental factors. Mineral mobilizing bacteria in soil mitigate the adverse effects of such stress by enhancing photosynthesis as well as plant biomass in a more time-sensitive and cost-effective manner.

The systems biology of plant-microbe interactions in response to environmental stimuli such as salinity, opens what are symbiotic bacteria new prospects of understanding the regulatory networks of plant salt tolerance what are symbiotic bacteria by such bacteria. While the induced salt tolerance may be contributed by the induction of various mechanism that function as chemical signals to the plant. Stress adaptation of plants are induced by associated mineral mobilizing bacteria and cutting-edge research may be successfully applied to improve crop yield in saline prone regions.

The potential application of mineral mobilizing bacteria to help plants deal with stress in agricultural fields seems vastly large, yet much is left to be utilised. Previous page.

Similarly to many bacterial pathogens, rhizobia are able to inject proteins, called effectors, into the plant cells by means of different protein secretion systems such as type III T3SSstructurally related to bacterial flagella, and the recently described type VI T6SSsimilar to the tail spike of the T4 phage. More than 50 years ago, Buchner published his microscopic observations in a compendium of insect-associated bacteria. Scale insects or cochineals feed on the sap of plants, which what are symbiotic bacteria rich in carbon but poor in nitrogen and so they require symbionts to compensate for diet deficiencies.
