Plant-Growth-Promoting Rhizobacteria

Annual Review of Microbiology, 2009
Several microbes promote plant growth, and many microbial products that stimulate plant growth have been marketed. In this review we restrict ourselves to bacteria that are derived from and exert this effect on the root. Such bacteria are generally designated as PGPR (plant-growth-promoting rhizobacteria).

Increased Plant Fitness by Rhizobacteria

2004
About half of the recently fixed carbon in plant leaves is transported below ground where a substantial fraction is released by growing plant roots as exudates and lysates. These nutrients attract bacteria and fungi, which multiply in the rhizosphere to densities up to and exceeding 100 times those in the bulk soil (Lynch and Whipps 1991).

Rhizobacteria and Plant Sulfur Supply

2007
Publisher Summary Sulfur is an absolute requirement for growth of all organisms. Its most important role is in the amino acids, cysteine and methionine, in proteins, where cysteine residues, in particular, are important in determining enzyme structure, and the metal-binding properties of sulfur help catalyze a variety of enzyme reactions.

Signalling in Rhizobacteria-Plant Interactions

2003
Bacteria are by far the most abundant organisms in soil and they play a key role in nutrient cycling and soil fertility. The rhizosphere — the zone of 1–2 mm around plant roots — is rich in nutrients and provides niches different from those in bulk soil for bacteria to thrive. Microbial diversity in the soil and in the rhizosphere is huge.

Osmotic stress adaptations in rhizobacteria

Journal of Basic Microbiology, 2012
Abstract Rhizobacteria have been reported to be beneficial to the plants in many different ways. Increasing salinity in the coastal agricultural zones has been shown to be a threat to the plant and microbial life in the area. Exposure of microorganisms to high‐osmolality

Rhizobacteria in Management of Agroecosystem

2013
Agriculture has a long history of research targeted at understanding how to improve the effectiveness of root symbionts, viz., rhizobia and mycorrhiza. A promising approach has been employed to understand how natural selection regulates changes in mutualistic interactions.

Application of Rhizobacteria for Induced Resistance

European Journal of Plant Pathology, 2001
This article provides a review of experiments conducted over a six-year period to develop a biological control system for insect-transmitted diseases in vegetables based on induced systemic resistance (ISR) mediated by plant growth-promoting rhizobacteria (PGPR). Initial experiments investigated the factors involved in treatment with PGPR led to ISR to

Biology of nitrogen-fixing Rhizobacteria

Plant and Soil, 1991
In non-legumes associative nitrogen-fixing system, several genera of rhizobacteria have been reported. The object of this paper is to summarize the current understanding of how rhizobacteria adhere to the root surface of non-legumes especially rice and other cereal crops. Evidence for involvement of rice lectin in adhesion will be reviewed. An emphasis

Role of Rhizobacteria in Drought Tolerance

2019
Drought is the most destructive abiotic stress affecting the world’s food security. Rhizospheric and endophytic bacteria produce range of enzymes and metabolites, which help the plants to tolerate abiotic stress. Induced systemic resistance gets developed in plants surviving in drought conditions.
