“…The symbiosis between AMF and higher plants also includes a network of extraradical mycelium (ERM) that extends beyond the rhizosphere. This network allows the exploitation of a larger amount of soil and enhances the acquisition of nutrients, including nitrogen and phosphorus, especially those that have limited mobility (Duponnois et al, 2008; Goss et al, 2017). The zone influenced by mycorrhizal roots and the extraradical hyphae is called the mycorrhizosphere (Linderman, 2008).…”

In cropping systems, the choices adopted for the tillage system used and plants cultivated can strongly influence the soil microbial population and its functional profile. Arbuscular mycorrhizal fungi are an important component of soil microbiome and their mutualistic symbiosis with the majority of higher plants grant the latter a wide range of benefits. The extraradical mycelium developed by these fungi expands the volume of soil influenced and harbours a diversity of microbes establishing a distinct environment of complementary interactions. We assessed how growing plants with different levels of mycotrophy modifies the biological activity profile in the soil under Mn toxicity and whether this is modified by soil disturbance. Following mycotrophic plants, soil contained a more active microbiome than after the non-mycotrophic plants, as expressed by higher values of soil basal respiration or dehydrogenase activity. Additionally, the count of phosphorus solubilizes and activity of phosphatase were greater after mycotrophic plants.Even among mycotrophic plants, different profiles of biological activity can be distinguished after growing a legume or grass. ERM disruption by soil disturbance decreased most of the parameters studied and for phosphatase activity and P solubilizers in a more significant way. These results indicate that even under Mn toxicity, the microbiome associated with AMF symbiosis following mycotrophic plants growth presented a higher biological activity and had a differential biological response towards the stress imposed by soil disturbance, when compared with the microbiome associated with non-mycotrophic roots.

“…Owing to the associated mycorrhizas in roots, the zone surrounding individual fungal hyphae of arbuscular mycorrhizas is de fi ned as "mycorrhizosphere" (Andrade et al 1998 ) . Mycorrhizosphere communities have exhibited the important roles in both plant growth and soil fertility (Duponnois et al 2008 ) . AMF are the "normal" condition in citrus rhizosphere for forming AM structures in roots ( Fig.…”

Rhizosphere, the soil region nearest to plant root system, inhabits various microorganisms varying in their community structure and diversity, still remains largely unexploited despite so much of breakthroughs in isolation and characterization, but lacks in addressing citrus speci fi c rhizosphere properties. Exploiting microbial synergisms is one of the popular methods of substrate dynamics and associated changes in nutrient environment of rhizosphere. Soil microbial biomass dominates fungal mycelium accumulates and retains mineral nutrients, immobilizing as much as ~20% of the total soil N and P. The extraradical mycorrhizal mycelial (attains as much as 3% of root weight) networks are recognized as the hidden nutrient/ water-absorbing interfaces (glomalin, a soil-based glycoprotein secreted by AMF as a major seat of activity) in addition to safeguarding citrus against a number of other biotic and abiotic stresses. The microbial diversity existing within top 0-20-cm citrus rhizosphere soil was characterized and isolated by the promising microbes, namely, Bacillus polymyxa , Azoto bacter chroococcum , Bacillus mycoides , Pseudomonas fl uorescens , and Trichoderma harzianum . Pure culture of these microbes in value-added form ( Bacillus polymyxa 33-44 × 10 6 -10 7 cfu mL −1
