Plant-growth-promoting rhizobacteria (PGPR) are associated with plant roots and augment plant productivity and immunity; however, recent work by several groups shows that PGPR also elicit so-called 'induced systemic tolerance' to salt and drought. As we discuss here, PGPR might also increase nutrient uptake from soils, thus reducing the need for fertilizers and preventing the accumulation of nitrates and phosphates in agricultural soils. A reduction in fertilizer use would lessen the effects of water contamination from fertilizer run-off and lead to savings for farmers.

Plant growth-promoting rhizobacteria modulate root-system architecture in Arabidopsis thaliana through volatile organic compound emission (2010, background): “PGPR can also induce defense programs such as systemic acquired resistance and induced systemic resistance, thus reducing the effects of phytotoxic microbial communities (Compant et al. 2005), or even elicit induced systemic tolerance (IST) to abiotic stress (Zhang et al. 2008b; Yang et al. 2009).”
Potential biological control of clubroot on canola and crucifer vegetable crops (2011, background): “In most systems involving biocontrol agents, the extent of rhizosphere colonization by the biocontrol agent is important in their efficacy against soil-borne pathogens (Yang et al., 2009; Begum et al., 2010).”
