Plant growth promoting Rhizobacteria: An overview

  title={Plant growth promoting Rhizobacteria: An overview},
  author={Ambreen Akhtar and Hisamuddin and Merajul Islam Robab and Abbasi and Rushda Sharf},
  journal={Journal of Natural Product and Plant Resources},
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).Of the microorganisms that parasitize on nematodes and reduce nematode populations by antagonistic behaviour, bacteria hold an important position where some of them have shown great potential as biocontrol agents. Bacteria destroy… Expand
Potential of plant growth-promoting rhizobacteria in the management of nematodes: A review
This literature survey provides an overview of research on biological control of economically important phytonematodes using rhizobacteria. Expand
Ph ton Diversity of Mycorrhizal fungi isolated from the rhizospheric soils of various Chilli plants
Numerous species of soil fungi which flourish in the rhizosphere of plants have shown great potential as biocontrol agents and a few also promote the growth of plants by an improved nutrient supply.Expand
Exploring the efficacy of antagonistic rhizobacteria as native biocontrol agents against tomato plant diseases
The present review article addresses the usage of rhizospheric antagonistic bacteria as a suitable alternative to control tomato fungal diseases namely Fusarium wilt and early blight disease and deals with the opportunities and obstacles faced during commercialization of these antagonisticacteria as biocontrol agents in the market.

Isolation, Characterization of Nematode-Controlling Bacteria and Fungi from Nature
The root-knot nematodes are a major endoparasitic pest affecting the production of many economically valuable annual and perennial crops worldwide in tropical and subtropical climatic zones and the use of native biocontrol agents as an integral component of integrated disease management is advocated. Expand
Biocontrol of Meloidogyne sp. on Tomato Plants by Selected Bacillus spp
Meloidogyne spp., are recognize as the most economically important worldwide. It is difficult to control Meloidogyne spp., because they have wide range of hosts. Due to the high toxicity of chemicalExpand
Screening, plant growth promotion and root colonization pattern of two rhizobacteria (Pseudomonas fluorescens Ps006 and Bacillus amyloliquefaciens Bs006) on banana cv. Williams (Musa acuminata Colla).
It is demonstrated that inoculation of rhizobacteria Bacillus amyloliquefaciens Bs006 and Pseudomonas fluorescens Ps006 could partially replace the chemical fertilization of tissue cultured banana plants, and therefore could be used for the formulation of a new biofertilizer. Expand
Microbial Inoculants in Sustainable Agricultural Productivity
The technology of plant production always faced fast-growing food and energy demands, but driven by a new approach, the answer for those demands must be socially and environmentally conscious. InExpand
Application of Bacillus species for controlling root-knot nematode Meloidogyne incognita in eggplant
The tested biocontrol agents used more than once or in combination are more effective than those used only once in controlling nematode parameters in eggplant under greenhouse conditions with a consequent increase in Eggplant growth. Expand


Plant Growth-Promoting Rhizobacteria (PGPR)
The work to date is very promising and may offer organic growers with some of their first effective control of serious plant diseases. Expand
Bacteria Involved in Nitrogen-Fixing Legume Symbiosis: Current Taxonomic Perspective
An overview of the main different groups of bacteria known up to date to be able of forming symbiosis with legumes is made and the symbiotic features of such bacteria scrutinizing the frontier of legume and bacteria promiscuity are discussed. Expand
Nematode interactions with root-nodule bacteria
In contrast, plant—nematode relationships can be characterized by host efficiency (degree of nematode reproduction) and host sensitivity ( degree of yield loss) (Cook, 1974). Expand
The rhizosphere : biochemistry and organic substances at the soil-plant interface
Rhizosphere as a site of biochemical interactions among soil, plant and microorganisms type and amounts of compounds released by plants in the rhizosphere the release of exudates as affected by theExpand
Formulation and delivery systems of biocontrol agents with emphasis on fungi
For commercial development of microbials for bioncontrol of soilborne pathogens in the spermosphere or rhizosphere, obstacles in growth, formulation, and delivery must be overcome. Most of theExpand
Induced resistance and phytoalexin accumulation in biological control of Fusarium wilt of carnation by Pseudomonas sp. strain WCS417r
The involvement of mechanisms other than competition for iron in biological control of Fusarium oxysporum f. sp. dianthi of carnation by Pseudomonas sp. strain WCS417r was investigated. Pathogen andExpand

The small (119-nt) RNA RsmX discovered in this study forms a triad of GacA-dependent small RNAs, which sequester the RNA-binding proteins RsmA and RsmE and thereby antagonize translational repression exerted by these proteins in strain CHA0. Expand
Control of pathogens An excellent volume has been prepared by TRAPPMAN7 on control of the pathogens (Pflanzen Schadlinge) of plants, in which he includes all living agents, parasitic andExpand
Current Concepts in the Use of Introduced Bacteria for Biological Disease Control: Mechanisms and Antifungal Metabolites
Rapidly evolving technologies from molecular biology and genetics have provided new insights into the underlying mechanisms by which biocontrol agents function and have allowed evaluation of the behavior of microbial inoculants in natural environments to a degree not previously possible. Expand
