Abstract Plant Growth Promoting Rhizobacteria (PGPR) are beneficial soil bacteria that can
live either symbiotically with plants at rhizosphere or as endophytes living on or inside of the …

Food is the primary requirement for the survival of mankind. Therefore food has always been
an issue since prehistoric times. Food production through agriculture is a key process to …

The microorganisms with the aim of improving nutrients availability for plants is an important
practice and necessary for agriculture. During the past couple of decades, plant growth …

Over the years, PGPR have gained world-wide importance and acceptance for agricultural
crops. The PGPR are naturally occurring soil bacteria that aggressively colonize plant roots …

The rhizosphere is the soil–plant root interphase and in practice consists of the soil adhering
to the root besides the loose soil surrounding it. Plant growth-promoting rhizobacteria …

The term “plant-growth-promoting rhizobacteria”(PGPR) include soil bacteria that colonize
the roots of plants following inoculation onto seed and enhance plant growth. The bacteria …

This review focuses on the present knowledge about beneficial free-living soil bacteria that
associate closely with plant as plant growth-promoting rhizobacteria (PGPR). Growth …

The rhizosphere is a zone of soil surrounding to the plant roots, where the biology and
chemistry of the soil is influenced by root metabolites pumped into the soil, called root …

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 …

Soil microbial communities are often difficult to characterize, mainly because of their
immense phenotypic and genotypic diversity. In the last ten years, a number of PGPR that …
