Abstract

Plant growth promoting rhizobacteria (PGPR) have gained worldwide importance and acceptance for agricultural benefits. This is due to the emerging demand for dependence diminishing of synthetic chemical products, to the growing necessity of sustainable agriculture within a holistic vision of development and to focalize environmental protection. Scientific researches involve multidisciplinary approaches to understand adaptation of PGPR, effects on plant physiology and growth, induced systemic resistance, biocontrol of plant pathogens, biofertilization, and potential green alternative for plant productivity, viability of coinoculating, plant microorganism interactions, and mechanisms of root colonization. By virtue of their rapid rhizosphere colonization and stimulation of plant growth, there is currently considerable interest in exploiting these rhizosphere bacteria to improve crop production. The main groups of PGPR can be found along with the phyla Cyanobacteria, Actinobacteria, Bacteroidetes, Firmicutes, and Proteobacteria. Therefore, the examples coming up next are related to these microorganisms. Although taxonomic affiliation of validated genera containing PGPR strains described in literature is vast, phenotypic and genotypic approaches are now available to characterize these different rhizobacteria. The progress to date in using PGPR in a variety of applications is summarized and discussed here.
