The culture of wheat (Triticum aestivum L.) is the second largest in the world and Brazil ranks the second in production in South America. However, this grain is attacked by several pathogens that compromise the yield. One of these pathogens is Magnaporthe grisea, a well known fungus that infects rice, causing rice blast, identified in wheat cultivation a few decades ago. It is worrying researchers and farmers because it mainly infects the aerial parts and might cause grain losses, however, it has been recently discovered that this fungus has the ability to infect the roots and spread to the rest of the tissues due to the similar structures of the soil fungus Gaeumannomyces graminis-tritici, the causal agent of take-all disease. Thus, with this project, we intend to access the microbial community associated with the roots of T. aestivum grown in soils suppressive to wheat blast caused by Magnaporthe grisea to identify groups of microorganisms which may be responsible for the suppressiveness.
