phosphatase and phytase activity which in turn could possibly be of great practical

2.3 Physiological Functions of Phosphate-Solubilizing
Microorganisms
Phosphate-solubilizing microorganisms increase the overall performance of plants
by providing mainly soluble P to plants in different production systems. However,
they also benefit plants by other mechanisms (Fig.
2.1
). Indeed, PSM exhibit
multifunctional properties (Vassileva et al.
2010
; Yadav et al.
2011
; Khan
et al.
2013
); for example, they are known to synthesize siderophores (Hamadali
et al.
2008
; Wani et al.
2008a
; Tank and Saraf
2003
; Viruel et al.
2011
) and IAA and
gibberellic acid (Sattar and Gaur
1987
; Souchie et al.
2007
; Viruel et al.
2011
).
