rhizospheres and plant growth promoting rhizobacteria
The PGPR enhance plant growth by atmospheric nitrogen fixation, phytohormone production, specific enzymatic activity, plant protection from diseases by producing anti-biotic and other pathogen-depressing subtances such as siderophores and chelating agents (for references see [29])
Microbial cells can produce and sense signal molecules, allowing the whole population to spread as a biofilm over the root surface and initiating a concerted action when a particular population density is achieved. This phenomenon is known as quorum sensing, which, in combination with other regulatory systems, expands the range of enviromental signals that target gene expression beyond population density [30]. The nitrogen-fixing rhizobial bacteria, chemotactically attracted towards legume roots by certain root exudates, adhere to and colonize the root surface, and activate rhizobial nodulation genes, Nod factors. Many quorum sensing signal molecules such as N-acyl-homoserine lactones (AHLS) are produced which regulate expression and repression of the symbiotic genes [30].
Free-living as well as symbiotic PGPR can enhance plant growth directly by providing bio-available phosphorus for plant uptake, fixing nitrogen for plant use, sequestring trace elements like iron for plants by siderophores, producing plant hormones like auxins, cytokinins and gibberelins, and lowering of plant ethylene levels [31]. The use of PGPR in phytoremediation technologies is now being considered to play an impowtant role as adding PGPR can aid plant growth on contaminated sites [32] and enhance detoxilication of soil [33]. PGPR are also beneficial to plants growing on derelict soils by conferring resistance to water stress in tomatoes and peppers [33]. The properties of plants used for phytoremediation, e.g. biomass production, low level contaminant uptake, plant nutrition and health, are improved by PGPR but it is important to choose PGPR which can survice and succeed when used in phytoremediation practices. Pairing PGPR with arbuscular mycorrhizal fungi (AMF) may be a good way of increasing the efficiency of phytoremediation . Although the role of PGPR is potentially important in the phytoremediation strategies, research in this area, as pointed out by Lucy et al. [34], is very limited and requires feild studies to support greenhouse or growth chamber results.
