“…Despite the demonstrated benefits produced by soil microorganisms, there is ample space for gaining further insight, especially on arbuscular mycorrhizal fungi, which are crucial for many ecosystem services, such as nutrient cycling and food production. An example is the case of Latin America [118]. In Latin America [119] and Africa there is a need to focus on soil health and biodiversity among farmers, major agribusinesses, and policy makers, complementing the current productivity paradigm with sustainability and conservation objectives.…”

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.

“…Despite this impressive range of ecological conditions that can be seen as natural laboratories, many groups of organisms are not well studied in South America. Soil microorganisms are particularly under‐studied (Cameron et al ., ), especially mycorrhizal fungi (Bueno et al ., 2017a; Marín & Bueno, ), which are crucial for many ecosystem services, as nutrient cycling and food production (van der Heijden et al ., ).…”

“…These knowledge gaps have limited the ability of scientists to address ecological and evolutionary questions related to the distribution and role of mycorrhizal fungi in the face of current environmental changes. The overall limitations for the development of such biodiversity studies in South America lie in an historic shortage of connections between the human and technical research resources (Marín & Bueno, ). In this context, ecological research networks are increasingly used tools to overcome these and related constraints (Richter et al ., ).…”

“…Despite its modest scientific productivity in comparison to other regions, mycorrhizologists in South America have developed a general baseline of mycorrhizal research, but there are still important knowledge gaps (Marín & Bueno, ). For example, large plant and mycorrhizal fungi trait databases are fundamental to address biogeographic or evolutionary questions, where South American studies and datasets are scarce.…”

“…Under this stressing soil conditions, AMF increases the plant tolerance to acidic and very dry soils with high amounts of heavy metals and lower amounts of crucial nutrients as phosphorus (Aguilera et al 2017;Santander et al 2019). Despite all these roles, it is surprising that AMF have been barely studied in commercially important species as bamboo (Jiang et al 2013;Muthukumar and Udaiyan 2006), and also very little in the Cerrado region (Marín and Bueno 2019). In order to understand the ecological interactions, geographical distribution, biogeochemical cycles, and the potential of restoration and micro-propagation of bamboo, it is fundamental to elucidate the composition of the associated AMF community, as these symbiont fungi are crucial in all these processes.…”

Most studies on bamboo have evaluated their commercial use but few have investigated their associated arbuscular mycorrhizal fungi (AMF). These symbiont fungi are fundamental on plant growth, nutrient cycling, biodiversity maintenance, etc., particularly on acidic/dystrophic soils as those of the Brazilian Cerrado. This study aimed to characterize the community composition and ecological interactions of AMF associated with the bamboo species Actinocladum verticillatum and Bambusa vulgaris vittata, under Cerrado vegetation in central Brazil. Roots and rhizospheric soil samples of A. verticillatum and B. vulgaris vittata were collected on 12 plots in the Gurupi (Tocantis state) and Porangatu (Goiás state) microregions. The roots' mycorrhizal colonization rate, rhizospheric soil' spore density, and the associated AMF genera were evaluated. There were no differences in the radical mycorrhizal colonization rates among the two bamboo species, although B. vulgaris vittata showed higher spore density than A. verticillatum. The genera Acaulospora, Claroideglomus, Diversispora, Scutellospora, Glomus, and Gigaspora were identified in both bamboo species, while Sclerocystis was present only on A. verticillatum. The genera Acaulospora, Diversispora, and Glomus were frequently found together. This study may be a first step to future AMF-based bamboo micropropagation efforts in the Cerrado Brazilian vegetation.
