...Cyanobacteria have been shown to colonize plant roots (Gantar et al., 1991; Lundberg et al., 2012), promote plant growth (Prasanna et al., 2009) and are an important plant source for inorganic N due to their ability to fix N (Franche et al., 2009)....

...The PGPM can be classified into three dominant groups of microorganisms: arbuscular mycorrhizal fungi (AMF) [107], plant growth promoting rhizobacteria (PGPR) [108], and nitrogen fixing rhizobia [109], which are deemed to be beneficial to plant growth and nutrition....

...The interactions may take place between plant and fungus/bacteria in which both partners get benefits as mutualistic association (Beattie, 2007; Finlay, 2007) and ultimately plant growth enhances due to growth promotion mechanisms used by microbes such as production of phytohormones, suppressing of pathogens, nitrogen fixation and solubilization of minerals (Ahmad et al., 2008; Bootkotr and Mongkolthanaruk, 2012; Franche et al., 2009; Hayat et al., 2010; Saharan and Nehra, 2011)....
