“…This result may be due to the diminishing activity of one of the organisms inoculated in the co-inoculation as a result of competition with another one or with the native bacteria. In this sense, the relationships, synergism or competition must be considered for the mixture of organisms to guarantee that co-inoculation will be effective for the plants [27]. According to the current knowledge of soil-plant-microbe interactions, the plant rhizosphere is a favorable habitat for various bacterial species, and there is intense competition within this habitat [28,29].…”

Drought conditions have made it difficult for farmers to ensure the productivity of their crops. The objective of this study was to evaluate the potential of bioinputs in stress mitigation after a drought event in common beans. Two experiments were set up in a greenhouse. Firstly, two types of soils (clayey and sandy loam) were used. After seedling emergence, treatments were set: no bacteria inoculation (NB) and inoculation with Herbaspirillum frisingense AP21. Then, a differentiation on the irrigation (15 days) was performed with no water restriction (NWR) and with water restriction (WWR). Transpiration, stomatal conductance, leaf dry matter and proline were measured. Secondly, in the clayey soil, the bacteria treatments were NB, Herbaspirillum frisingense AP21, Rhizobium leguminosarum T88 and co-inoculation (AP21 + T88). A differentiation on the irrigation (15 days) was performed: NWR and WWR. Then, Fv/Fm, photosynthetic rate, proline and sugars were assessed, and the harvest occurred 97 days after emergence. For sandy loam soil bioinputs, they did not have an effect on the parameters evaluated. For clayey soil, H. frisingense AP21 increased the transpiration rate and stomatal conductance and hence improved the leaf dry matter in comparison to NB. Under WWR, the isolated inoculations of AP21 and T88 increased grain dry matter, but the co-inoculation showed low grain production, similar to no bacteria inoculation.

“…Microbial inoculants are often formulated in laboratories with weak containment controls and transported insecurely (140); invasive disease-causing organisms have escaped from labs (147-150); and quality control is lax for the manufacture of some inoculants (151). ( 6) Propagule pressure Which European bird species became established in New Zealand was primarily determined by the number of introduced individuals and the frequency of introductions -(their propagule pressure) with large numbers of individuals increasing the likelihood of establishment (152).…”

The use of non-genetically modified microbial inoculants for beneficial purposes in agriculture, bioremediation, medicine, and infrastructure is increasing. The intentional introduction of plants and animals for similar purposes has a long history, but despite successes, has resulted in thousands of plant and animal species becoming invasive, with catastrophic consequences for the environment, public health, and society. Hundreds of microbial invasions are known, and although microbial inoculants can provide benefits, they have similar potential to negatively impact ecosystems. Little action has been taken to guard against the threat of microbial invasions from non-genetically modified microbial inoculants. Now is the time to develop an effective research and management infrastructure for these microbial inoculants to avoid catastrophic outcomes similar to those caused by intentionally-introduced plants and animals. Here, we propose a unified research and management approach to spur action by regulators and practitioners. Three aims need to be addressed: developing (1) a coherent mechanistic understanding of how microbial inoculants effect invasions, (2) predictive models forecasting which microbes pose risks of invasion, and (3) effective management strategies. To guide mechanistic understanding, we develop seventeen key hypotheses. For predictive modeling, quantitative trait analysis and risk maps will be critical. Management strategies will depend on both understanding and predictions, but prevention rather than eradication or control of invasive microbes is likely to be most effective, and a precautionary regulatory approach should immediately be applied to inoculants. Multiple data types will be instrumental for understanding and predicting which microbial inoculants have invasive potential: experimental data from microcosm and mesocosm experiments, and large-scale observational data from microbial surveillance. Both phenomenological and mechanistic modeling approaches will be key in achieving these fundamental and applied research aims. Moreover, each stage of the invasion process --- transport, establishment, spread, and impacts --- often need to be investigated separately. The unified approach developed here provides a roadmap for developing a research and management infrastructure to guard against the threat of microbial invasions from non-genetically modified microbial inoculants.

“…The most used species in commercial inoculants are Rhizophagus irregularis and Funneliformis mosseae which are known for their ubiquity, their generalist habits, and their ability to colonize a wide variety of plants [70]. Most of AMF inoculants are well proven based on inducing growth promotion, improving nutritional status, and protecting against biotic and/or abiotic factors for important horticultural, forestry, and agricultural plant species [71,72,73].…”

The rhizosphere is the soil that surrounds, and is influenced by, the roots of a plant. It is considered one of the most complex ecosystems on the planet due to the intense interactions that occur between plants and microorganisms, as well as the competition that occurs among the microbial components. Due to this competition and beneficial interactions, a contribution of paramount relevance occurs in terms of chemical, physical, and biological characteristics that allow the plant and crop development. To mitigate ecosystem disturbances, it is necessary to compensate the imbalance of these conditions. Unfortunately, human activities involving strong soil disturbance have significantly affected plant development. Therefore, currently it is a priority to avoid the deterioration of soil ecosystems to remediate the damages that have already occurred. In the case of soil microbiology area, there are many solutions that can be designed and applied with beneficial microorganisms, including both fungi and bacteria, that interact mutualistically with plants or crops. At the same time, a deep understanding of these interactions remains challenging due to their complexity. In this review, biotechnological developments with agricultural or forestry importance are analysed. These include plant growth promoter bacteria, the Azolla-Anabaena symbiotic system, arbuscular mycorrhizal fungi and ectomycorrhizal fungi, as well as their relevance in the production of agricultural and forestry biofertilizers.
