Microorganisms has vital role in agriculture in order to promote the exchange of plant nutrients and reduce application of chemical fertilizers as much as possible. Plant Growth-Promoting Rhizobacteria (PGPR) is able to exert a positive effect leading plant growth. Beneficial plantâ microbe interactions in the rhizosphere can influence plant vigor and soil fertility. These beneficial effects of PGPR have direct or indirect performance on plants. Direct promotion of growth by PGPR including production of metabolites that enhances plant growth such as auxin, cytokinins, gibberellins and through the solubilization of phosphate minerals. Indirect growth promotion occurs via the removal of pathogens by the production of secondary metabolites such as hydrogen cyanide and siderophores. Plants are regularly concerned in interactions with a broad range of bacteria that colonize the rhizosphere (rhizobacteria), the phyllosphere (epiphytes), and the inside of plant tissues (endophytes).
