Development of agricultural bio-inoculants based on mycorrhizal fungi and endophytic filamentous fungi: Co-inoculants for improve plant-physiological responses in sustainable agriculture

A new more sustainable agricultural system needs to be developed increase production without compromising human and animal health preserving essential resources, such as soil, water diversity. Bio-inoculants can a tool favor this transition, they replace or complement agrochemicals that do not meet the above premises. generated from endophytic filamentous fungi mycorrhizal fungi, whether used individually, in combination with each other microorganisms, stand out for their potential. This review provides information on how bio-inoculants based these microorganisms have been shown crop yield quality through strategies, increasing nutrient uptake levels of certain phytohormones. On promote tolerance abiotic stresses, including heavy metals, elevated temperatures, salinity drought, accumulation osmoregulatory substances plant's root surface, among others. And finally, ability protect plant against pathogens pests, either by inducing defense systems, competing space synthesizing metabolites antibiotic activity. It should noted that, although there are already commercial products using purposes, biological control agents biostimulants, it is expected deeper understanding mechanisms action together improved technical processes, will lead effective, safer cheaper products.
