Plant-Growth-Promoting Rhizobacteria

Resonance, 2013
About 2–5% of rhizobacteria, when present in large number, are able to promote plant growth. Production of plant hormones and improving mineral nutrition are examples of direct promotion, while protecting plants against many diseases caused by bacteria, fungi, viruses, nematodes, or insects is indirect mechanism of growth promotion.

Osmotic stress adaptations in rhizobacteria

Journal of Basic Microbiology, 2012
AbstractRhizobacteria 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 environments triggers rapid fluxes of cell water along the osmotic gradient out of ...

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.

Characterization of exopolysaccharides produced by rhizobacteria

Applied Microbiology and Biotechnology, 1992
Bacteria isolated from the rhizosphere, the rhizobacteria, of sorghum, pearl millet, wheat, alfalfa and rice were screened for the production of exopolysaccharide (EPS). Nearly a quarter of the strains produced exopolysaccharides, either capsular or hydrosoluble slime. A majority of the isolates produced slime.

Biological control of pathogens with rhizobacteria

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1988
Abstract Present knowledge on the biological control of soil-borne plant pathogens by rhizosphere inhabiting bacteria, especially fluorescent Pseudomonas spp., is discussed. Attention is paid to the use of molecular biological techniques to analyse the mechanism(s) of antagonism (competition for iron, antibiosis) and the population ...

GREENHOUSE SCREENING OF RHIZOSPHERE BACTERIA FOR PLANT GROWTH PROMOTING RHIZOBACTERIA AND DELETERIOUS RHIZOBACTERIA OF MAIZE

2015
Mısır rizosferinden elde edilen 576 bakteri izolatı bitki büyümesini teşvik edici ve zararlı etkileri yönünden serada iki patojenin de bulunduğu topraklarda test edilmiştir. Seçilen izolatlar serada tekrar test edilmiştir. Çoğunlukla bakteri izolatları mısır bitkisinin boyu üzerinde istatistiki bakımdan önemli bir etki göstermemişlerdir. Bitki boyu ile
