...In some PGPR species, plant growth promotion dominates with nitrogen fixation, phosphate solubilization and production of phytohormones like auxin and cytokinin and volatile growth stimulants such as ethylene and 2, 3-butanediol (Ryu et al. 2003; Vessey 2003)....

...The concept of PGPR has now been confined to the bacterial strains that can fulfil at least two of the three criteria such as aggressive colonization, plant growth stimulation and biocontrol (Weller et al. 2002; Vessey 2003)....

...Allorhizobium, Azorhizobium, Bradyrhizobium, Mesorhizobium, Rhizobium and Sinorhizobium are reported as the potent PGPR strains for their ability to act as biofertilizers (Vessey 2003)....

...A similar investigation on rhizobia to replace the use of nitrogen fertilizer was made by Vessey (2003) and thereby demonstrated a clear picture of improvement in crop yield after the inoculation of rhizobacteria in agricultural soil....

...Furthermore, in most studied cases, a single PGPR will often reveal multiple modes of action including bio- logical control (Kloepper, 2003; Vessey, 2003)....

...In accordance with Vessey (2003), soil bacterial species burgeoning in plant rhizosphere which grow in, on, or around plant tissues stimulate plant growth by a plethora of mechanisms are collectively known as PGPR (plant growth promoting rhizobacteria)....

...There is ample evidence that the mode of action of many PGPR is by increasing the availability of nutrients for the plant in the rhizosphere (Glick, 1995; Rodriguez and Fraga, 1999)....

...While some believe that there contribution of these siderophores to the overall iron requirements of plants is small (Glick, 1995), other suggest an important role (Duijff et al., 1994), even a vital role, especially in calcareous soils (Masalha et al., 2000)....

...Although the action of biopesticidal PGPR is often an antogonistic effect on fungal pathogens of plants (Whipps, 2001), biofertilizing PGPR sometimes enhance plant growth indirectly by stimulating the relationship between the host plant and beneficial rhizospheric fungi such as arbuscular…...

...Glick et al. (1998) put forward the theory that the mode of action of some PGPR was the production of 1-aminocyclopropane1-carboxylate (ACC) deaminase, an enzyme which could cleave ACC, the immediate precursor to ethylene in the biosynthetic pathway for ethylene in plants....
