“…The induction of chitinase, β-1, 3 glucanase and increase in total phenol content was also observed, suggesting their role in growth inhibition of pathogen during antagonism (Gajera et al, 2012). Similarly, Brettanomyces naardensis, an antagonistic and growthpromoting yeast, is a potent biocontrol agent for M. phaseolina that colonizes fungal hyphae causing malformation and damage (Nafady et al, 2019).…”

Macrophomina phaseolina is a generalist soil-borne fungus present all over the world. It cause diseases such as stem and root rot, charcoal rot and seedling blight. Under high temperatures and low soil moisture, this fungus can cause substantial yield losses in crops such as soybean, sorghum and groundnut. The wide host range and high persistence of M. phaseolina in soil as microsclerotia make disease control challenging. Therefore, understanding the basis of the pathogenicity mechanisms as well as its interactions with host plants is crucial for controlling the pathogen. In this work, we aim to describe the general characteristics and pathogenicity mechanisms of M. phaseolina, as well as the hosts defense response. We also review the current methods and most promising forecoming ones to reach a responsible control of the pathogen, with minimal impacts to the environment and natural resources.

“…Recent research has focused on exploiting beneficial microorganisms in crop management, including arbuscular mycorrhizal fungi (AMF), which are widely distributed in soils and can colonize the roots of most plant species [ 11 ]. Arbuscular mycorrhizal fungi belong to the Glomeromycota phylum [ 12 ], which is widely recognized to improve plant growth through the increase of nutrient and water absorption by plant roots and also through the improvement of soil structure [ 11 ]. One of the most important benefits of AMF for its host plants is the protection against diseases from soil pathogens, including fungi, bacteria, and nematodes [ 13 , 14 ].…”

In potato (Solanum tuberosum) crops, the use of fungicides to control some diseases is widespread; however, it has been reported that this practice can modify the potato polyphenolic content, and new strategies oriented to the potato defense system are necessary. One alternative is the use of arbuscular mycorrhizal fungi (AMF) to improve the defense mechanisms of plants. In this study, phenolic profiles and antioxidant activities in leaves of three potato genotypes (CB2011-509, CB2011-104, and VR808) were evaluated in crops inoculated with three AMF strains (Claroideoglomus claroideum, Claroideoglomus lamellosum, and Fumneliformis mosseae) and with AMF in combination with the use of two commercial fungicides (MONCUT [M] and ReflectXtra [R]). Eight phenolic compounds were detected, mainly hydroxycinnamic acids (HCAD) and flavonols, in samples where the highest concentrations of HCAD were obtained, 5-caffeoylquinic acid was the most abundant phenolic. The antioxidant activity was higher using the cupric reducing antioxidant capacity (CUPRAC) and ferric reducing antioxidant power (FRAP) methods. The association of AMF with plants had benefits on the secondary metabolism; however, the response differed according to genotype. The different combinations of potato genotypes, AMF strain, and fungicide modified the content of phenolic compounds in leaves in different ways; the treatment using C. lamellosum and ReflectXtra was the ideal combination for the genotypes analyzed here, with the higher antioxidant response, which supports the further technological evaluation of efficient AMF strains and fungicides in potato crops.

“…Some examples for smart agriculture are the reported associations of the bacteria Rahnella aquatilis which improves organic phosphorus solubilization when associated with the mycorrhizal fungus Rhizophagus irregularis. The rhizospheric yeast fungi Cryptococcus flavus or Candida railenensis and the arbuscular mycorrhizal fungus Rhizophagus irregularis whose association promotes root growth in corn plants [126]; the Brettanomyces naardensis yeast with fungi that reduce the incidence of the pathogen Macrophomina phaseolina in sunflower plants; in addition, this association significantly improves growth parameters such as plant height, dry weight and number of leaves [127]. It has also been reported that consortia between filamentous fungi and PGPR stimulate the growth and yield of substances produced by plants as essential oils [128].…”

Knowledge of the agricultural soil microbiota, of the microbial consortia that comprise it, and the promotion of agricultural practices that maintain and encourage them, is a promising way to improve soil quality for sustainable agriculture and to provide food security. Although numerous studies have demonstrated the positive effects of beneficial soil microorganisms on crop yields and quality, the use of microbial consortia in agriculture remains low. Microbial consortia have more properties than an individual microbial inoculum, due to the synergy of the microorganisms that make them up. This review describes the main characteristics, ecosystem functions, crop benefits and biotechnological applications of microbial consortia composed of arbuscular mycorrhizal fungi, plant growth promoting bacteria and actinobacteria, to promote the restoration of agricultural soils and, consequently, the quality and health of agricultural crops. The aim is to provide knowledge that will contribute to the development of sustainable and sufficiently productive agriculture, which will adapt in a good way to the pace of the growing human population and to climate change.
