Mycorrhizae: Potential Biocontrol for Crop Plants

Som Subhra Dutta, Somdatta Ghosh*

Besides functioning as an effective bio fertilizer mycorrhizae offers plant immunity to some degree, known as Mycorrhiza Induced Resistance (MIR) in plants. This immunity is effective against a variety of air and soil borne pathogens. Plant receptor protein complexes or pattern-recognition receptors recognize the Effector Proteins (EP) and Microbe-Associated Molecular Patterns (MAMPs) of mycorrhizae as these are very much related to other possible pathogens. So MAMP Triggered Immunity response (MTI) is activated in plants and inhibit further invasion of pathogens. This offer both short time and long-time defence in plant with systemic acquired resistance and induced systemic resistance. In this process defence related genes are activated in response to different pathogens and antipathogenic secondary metabolites are produced. Mycorrhizae also modify plant root exudates to attract beneficial microbes which also offer induced systemic resistance and act as consortium.
