Plant growth-promoting rhizobacteria (PGPR) are naturally occurring soil bacteria that aggressively colonize plant roots and benefit plants by providing growth promotion. Inoculation of crop plants with certain strains of PGPR at an early stage of development improves biomass production through direct effects on root and shoots growth. Inoculation of ornamentals, forest trees, vegetables, and agricultural crops with PGPR may result in multiple effects on early-season plant growth, as seen in… Expand
Potentialities of Bacillus strains for promoting growth in maize (Zea mays L.)
TLDR
The obtained results allowed selecting the native isolates ERM1, RM5, EAM5 and RM1 as the most promising to promote plant growth and their future use in the sustainable agriculture. Expand
Improvement of Phaseolus vulgaris growth by inoculation with multifunctional native rhizobacteria isolated from rhizospheric soils in Gaza strip- Palestine
TLDR
Results indicated that some bacterial combinations significantly increased plant growth, but no significant increase of total nitrogen concentration was observed, indicating the potential for developing biofertilizers for integrated nutrient management strategies and decrease chemical firtilizers abuse stratiges. Expand
Root associated iron oxidizing bacteria increase phosphate nutrition and influence root to shoot partitioning of iron in tolerant plant Typha angustifolia
TLDR
FeOBs that produce siderophore increased iron content in plant and therefore can be of immense biotechnological importance, however Biomass increase was directly correlated with increased phosphate acquisition and not with enhanced iron accumulation in Typha. Expand
Improving the productivity of cucumber through combined application of organic fertilizers and Pseudomonas fluorescens.
TLDR
In IPNMS, the use of plant growth promoting rhizobacteria (PGPR) to enhance crop productivity has gained significant importance and reduces agrochemical use and supports ecofriendly sustainable food production. Expand
Metabolic diversity of edaphic microorganisms associated with corn cultivation in the Yaqui Valley , Sonora
In the Yaqui Valley, like other sites with intensive agriculture, soils have been generated with low content of organic matter (< 1.5%), high levels of erosion due to wind events, saline or alkalineExpand

PGPR: Prospective Biocontrol Agents of Plant Pathogens
TLDR
Although significant control of plant pathogens has been demonstrated by PGPR in laboratory and greenhouse studies, results in the field have been inconsistent and progress in understanding of their diversity, colonizing ability, mechanisms of action, formulation and application should facilitate their development as reliable biocontrol agents against plant pathogens. Expand
Enhanced plant growth by siderophores produced by plant growth-promoting rhizobacteria
TLDR
Evidence is presented that PGPR exert their plant growth-promoting activity by depriving native microflora of iron by producing extracellular siderophores (microbial iron transport agents) which efficiently complex environmental iron, making it less available to certain nativemicroflora. Expand

TLDR
The results showed that inoculation with bacterial treatments had a more stimulating effect on growth and development of plants in nonsterile than sterile soil. Expand

The effect of plant growth-promoting rhizobacteria on asparagus seedlings and germinating seeds subjected to water stress under greenhouse conditions.
TLDR
Seed inoculations with PGPR resulted in a positive response only for 'Guelph Millennium', for which both single or multiple inoculations enhanced plant growth under drought stress, and single inoculations of seedlings enhanced growth of 'Jersey Giant" under optimum conditions. Expand
Beneficial plant bacteria
TLDR
Commercial applications of PGPR are being tested and are frequently successful; however, a better understanding of the microbial interactions that result in plant growth increases will greatly increase the success rate of field applications. Expand
Plant Growth Promoting Rhizobacteria Effect on Antioxidant Status , Photosynthesis , Mineral Uptake and Growth of Lettuce under Soil Salinity
TLDR
Investigation of the effects of plant growth promoting rhizobacteria (PGPR) on the antioxidant status, photosynthesis, mineral content and growth of lettuce under different soil salinity conditions found that an increase in salinity in the soil caused a physiological response or disorder in lettuce plants.

Effects of inoculation of plant growth-promoting rhizobacteria on metal uptake by Brassica juncea.
TLDR
Application of plant growth-promoting rhizobacteria, including nitrogen-fixing bacteria and phosphate and potassium solubilizers, might play an important role in the further development of phytoremediation techniques. Expand
The effect of plant growth promoting bacteria on growth and nutrient uptake of maize in two different soils
TLDR
The results suggest that plant growth stimulating efficiency of bacterial inoculants affected by soil nutritional condition has a much better stimulatory effect on plant growth in nutrient deficient soil than in nutrient rich soil. Expand
