The enhancement of plant growth by free-living bacteria 

 -  Can. J. Microbiol., 41(2), p.109-117, 1995 .
<br/><br/> The ways in which plant growth promoting rhizobacteria facilitate the growth of plants are considered and discussed. Both indirect and direct mechanisms of plant growth promotion are dealt with. The possibility of improving plant growth promoting rhizobacteria by specific genetic manipulation is critically examined.
