**14. The mycorrhiza helper bacteria**

Mycorrhiza derived from word "*mycorrhization*" was first given by two scientist Duponnois and Garbaye in 1991. They described that these bacteria are helpful in the formation of the plant root and fungus symbiotic relationship. MHB helps to increase the efficiency of mycorrhizal fungi, that is, absorption of different nutrients from soil, and to protect plant roots from pathogens attack and enhance the capacity of plants to uptake a growth factor. This would certainly offer a new measurement of the ecology, evolutionary, and physiology biology of mycorrhiza association. MHB may increase the efficacy of fungal inoculum with a less budget because bacteria are easily grown in profitable numbers than most MF. This research shows that more mycorrhiza helper bacteria work should be devoted to mycorrhizal fungi for commercial concerns as well as used as a laboratory models in research. These fungi include *Pisolithus* spp., *Laccaria bicolor*, and *Glomus intraradices* genomes that are being sequenced as arbuscular fungi ectomycorrhizas. In addition, growing concern about the pollution of soil and the resulting tendency toward reducing the input of chemicals in plant production should substitute eco-friendly practices such as controlled microbial bioremediation, for example, by using ECM fungi as carriers of depolluting bacteria [22]. Different investigation and research supported by the genomic development may be a great opportunity to place MHB in the top prior list of future mycorrhiza research and to increase general field of fungal-bacterial interactions in ecosystems.
