Abstract
There is a substantial and increasing effort to develop microorganisms for agricultural purposes to improve the sustainability and profitability of rural activities whilst increasing productivity. These are generically termed Plant Growth Regulating Rhizosphere organisms (PGPR), and the number of research groups that are involved in their isolation and/or characterisation is growing. Examples of PGPR organisms that have been shown to be beneficial include microbial biofertilisers, biocontrol agents for weed suppression, ana plant stimulants from Actinomycetes, and the fungal and bacterial genera Trichoderma, Penicillium, Pseudomonas, Agrobacterium, Azospirillum, Azotobacter, Acetobacter and Bacillus. The use of these organisms is now seen in the fields of agriculture, horticulture, forestry and environmental restoration. The specific 'mechanisms of plant growth enhancement by PGPR have not been well characterised but their modes of action are broadly divided into two categories, viz. enhancement of plant growth by indirect and enhancement of plant growth by direct means.
