Plant growth promoting rhizobacteria-an efficient tool for agriculture promotion 427 copright: 201 atiar et al citation: katiyar d, hemantaranjan a, singh b plant growth promoting rhizobacteria-an efficient tool for agriculture promotionadv plants agric res 20164(6):426‒434. Some plant growth-promoting rhizobacteria for example bacillus subtilis rc11 were efficient in phosphate solubilization and indole acetic acidity (iaa) production and considerably elevated development of wheat and green spinach (20. Plant growth-promoting rhizobacteria (pgpr) are the rhizosphere bacteria that can enhance plant growth by a wide variety of mechanisms like phosphate solubilization, siderophore production, biological nitrogen fixation, rhizosphere engineering, production of 1-aminocyclopropane-1-carboxylate.

Bacteria that colonize plant roots and promote plant growth are referred to as plant growth-promoting rhizobacteria (pgpr) pgpr are highly diverse and in this review we focus on rhizobacteria as biocontrol agents. Types of direct plant growth promotion which are discussed include (a) biofertilization, (b) stimulation of root growth, (c) rhizoremediation, and (d) plant stress control mechanisms of biological control through which rhizobacteria can promote plant growth not directly, ie by reduction of the amount of disease, include antibiosis, induction. Direct mechanisms of plant growth promotion include those metabolisms that, by supplying nutrients to the plant, enhance its fitness the established halotolerant/halophile bacteria collection was analysed for the capability to solubilise phosphate, fix nitrogen, and produce ammonia. The present study deals with the isolation and characterization of exopolysaccharides (eps) produced by the plant growth-promoting rhizobacteria (pgpr) from arid and semiarid regions of pakistan, and to investigate the drought tolerance potential of these pgpr on maize when used as bioinoculant alone and in combination with their respective eps.

Plant growth promoting rhizobacteria (pgpr) are beneficial bacteria that colonize plant roots and enhance plant growth by a wide variety of mechanisms five isolates of pgpr designated as pseudomonas aeruginosa strain bhupsb02, pseudomonas putida strain bhupsb04, bacillus subtilis strain bhupsb13, paenibacillus polymyxa strain bhupsb17 and bacillus boronophilus strain bhupsb19 were successfully. Numerous species of soil bacteria which flourish in the rhizosphere of plants, but which may grow in, on, or around plant tissues, stimulate plant growth by a plethora of mechanisms these bacteria are collectively known as pgpr (plant growth promoting rhizobacteria) the search for pgpr and. Plant growth promoting rhizobacteria (pgpr) the recognition of plant growth-promoting rhizobacteria (pgpr), a group of beneficial plant bacteria, as potentially useful for stimulating plant growth and increasing crop yields has evolved over the past several years to where today researchers are able. Plant growth promoting rhizobacteria as biocontrol agents against soil-borne plant diseases biological control of soil-borne plant diseases by means of plant growth promoting rhizobacteria.
