Engineering rhizobacteria for sustainable agriculture

The ISME Journal, 2020
Abstract Exploitation of plant growth promoting (PGP) rhizobacteria (PGPR) as crop inoculants could propel sustainable intensification of agriculture to feed our rapidly growing population. However, field performance of PGPR is typically inconsistent due to suboptimal rhizosphere colonisation and persistence in foreign soils, promiscuous

Use of rhizobacteria for biocontrol

Current Opinion in Biotechnology, 1993
Abstract Our understanding of the biochemical and genetic basis of the suppression of soil-borne plant pathogens by introduced rhizobacteria has advanced greatly over the last few years. It is known that secondary metabolites, such as the phenazines, 2, 4-diacetylphloroglucinol and hydrogen cyanide, have a critical role in the biocontrol of some ...

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.
