Baradar  A., Saberi Riseh  R., Sedaghati  E. & Akhgar A. 2015. Mycorrhiza helper bacteria. Plant  Pathology  Science 4(1):46-53.

Mycorrhizal fungi increase water and nutrient elements absorption to the plant and plant provide carbohydrates for the fungus and this is beneficial for both parties . Many plants need to these fungi for absorption some mineral elements and resistance to environmental stresses such as drought, soil contamination to heavy metals such as lead, zinc and cadmium. Some soil borne bacteria have been identified as third part of the mycorrhiza, which cause improving the performance of this symbiotic relationship, and have been named as mycorrhiza helper bacteria.

Mohammadi  M., Hosseini A., Sedaghati E. and Hosseini S. 2018. Mycoviruses  application in biocontrol of fugal pathogens. Plant Pathology Science 7(1):51-62.

Mycoviruses or fungal parasitic viruses have dsDNA, dsRNA or ssRNA genome. Some of these viruses have a restricted host range and can infect certain strains of host species. In contrast, some other viruses have wider host range and can infect different species of a fungal family. In most cases these viruses are transmitted by anastomosis of mycelium. In a phenomenon called hypovirulence, most of these viruses decrease the virulence of their host fungus. Discovery of  hypovirulence revealed the biocontrol ability of mycoviruses. In summary, mycoviruses could be implemented as powerful agents for biocontrol of fungal pathogens and induction of resistance in plants.
