Root Colonization by Inoculated Plant Growth-Promoting Rhizobacteria

Biocontrol Science and Technology, 2001
Certain rhizobacteria referred to as 'plant growth-promoting rhizobacteria' (PGPR) can contribute to the biological control of plant pathogens and improve plant growth. They enhance root development either directly by producing phytohormones, or indirectly by inhibiting pathogens through the synthesis of different compounds.

Plant Growth-Promoting Rhizobacteria for Plant Immunity

2013
Plants are equipped with active defense mechanisms, and in order to survive with diverse pathogen attack and unfavorable conditions, plants activate appropriate defense responses. However, defense response entails a great cost in the overall health of plants.

Applications of free living plant growth-promoting rhizobacteria

Antonie van Leeuwenhoek, 2004
Free-living plant growth-promoting rhizobacteria (PGPR) can be used in a variety of ways when plant growth enhancements are required. The most intensively researched use of PGPR has been in agriculture and horticulture. Several PGPR formulations are currently available as commercial products for agricultural production.

The importance of plant growth–promoting rhizobacteria for plant productivity

2021
Plant growth-promoting rhizobacteria (PGPR) naturally colonizes the plant roots and has positive effects on plant growth and physiology. In the soil ecosystem, PGPRs are responsible for a broad scope of biotic activities which improve soil nutrient turnover.

Plant growth promoting rhizobacteria as biofertilizers

Plant and Soil, 2003
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).

Ecology of Plant Growth Promoting Rhizobacteria

2006
Chapter presents a discussion on the term PGPR which underlines the need to have a uniform definition to be used by all authors. The actual biodiversity of PGPR will be illustrated by examples of genera and species chosen from the literature and their mechanisms of action for the following different groups: diazotrophs, bacilli, pseudomonads, and ...

Plant growth-promoting rhizobacteria (PGPR): emergence in agriculture

World Journal of Microbiology and Biotechnology, 2011
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 deaminase (ACC), quorum sensing (QS) signal interference and ...

Molecular basis of plant growth promotion and biocontrol by rhizobacteria

Current Opinion in Plant Biology, 2001
Plant-growth-promoting rhizobacteria (PGPRs) are used as inoculants for biofertilization, phytostimulation and biocontrol. The interactions of PGPRs with their biotic environment, for example with plants and microorganisms, are often complex. Substantial advances in elucidating the genetic basis of the beneficial effects of PGPRs on plants have been ...
