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 …

Plant growth-promoting rhizobacteria (PGPR) are a group of free-living bacteria that
colonize the rhizosphere and benefit the root growth. Bacteria of diverse genera were …

Résumé 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 …

The rhizosphere as compared to bulk soil is rich in nutrients because of root exudation and
deposits. As a consequence, the number of bacteria surrounding plant roots is 10–100 times …

Rhizobacteria are capable of stimulating plant growth through a variety of mechanisms that
include improvement of plant nutrition, production and regulation of phytohormones, and …

Certain rhizobacteria referred to as' plant growth-promoting rhizobacteria'(PGPR) can
contribute to the biological control of plant pathogens and improve plant growth. They …

Root colonizing bacteria (rhizobacteria) that exert beneficial effects on plant development
via direct or indirect mechanisms have been defined as plant growth promoting …

Plant growth results from interaction of roots and shoots with the environment. The
environment for roots is the soil or planting medium which provide structural support as well …

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 …

Plant growth-promoting rhizobacteria (PGPR) are free-living bacteria which actively colonize
plant roots, exerting beneficial effects on plant development. The PGPR may (i) promote the …
