“…No differences in Cd, P, or Fe contents were found between nM and M soybean soils. This result is in agreement with the Cd concentration values in soil reported for Lonicera japonica colonized by Glomus versiforme and R. intraradices [28]. Based on our results, we can only propose some possible explanations for this lack of differences in Cd, P, and Fe soil concentrations between M and nM soybean.…”

Cadmium is a heavy metal (HM) that inhibits plant growth and leads to death, causing great losses in yields, especially in Cd hyperaccumulator crops such as Glycine max (L.) Merr. (soybean), a worldwide economically important legume. Furthermore, Cd incorporation into the food chain is a health hazard. Oxidative stress (OS) is a plant response to abiotic and biotic stresses with an intracellular burst of reactive oxygen species (ROS) that causes damage to lipids, proteins, and DNA. The arbuscular mycorrhizal fungal (AMF) association is a plant strategy to cope with HM and to alleviate OS. Our aim was to evaluate the mitigation effects of mycorrhization with AMF Rhizophagus intraradices on soybean growth, nutrients, Cd accumulation, lipid peroxidation, and the activity of different antioxidant agents under Cd (0.7–1.2 mg kg−1 bioavailable Cd) induced OS. Our results suggest that glutathione may act as a signal molecule in a defense response to Cd-induced OS, and mycorrhization may avoid Cd-induced growth inhibition and reduce Cd accumulation in roots. It is discussed that R. intraradices mycorrhization would act as a signal, promoting the generation of a soybean cross tolerance response to Cd pollution, therefore evidencing the potential of this AMF association for bioremediation and encouragement of crop development, particularly because it is an interaction between a worldwide cultivated Cd hyperaccumulator plant and an AMF–HM–accumulator commonly present in soils.

“…Reported effects of AMF colonization on plant metal uptake are similarly inconsistent (e.g. Diaz et al 1996; Turnau and Mesjasz-Przybylowicz 2003; Chen et al 2005; Jiang et al 2016). …”

“…Other studies, largely in greenhouses, have typically found that metals decrease AMF colonization and/or diversity (del Val et al 1999a, b, Khan 2001, Chen et al 2005, although Diaz et al (1996) and Tan et al (2015) found no effect of applied Zn, Pb, or Cd solutions on AMF colonization of three host plants, and Vogel-Miku s et al (2006) found that increasing soil Cd and Pb by mixing contaminated and uncontaminated soils in different ratios increased AMF colonization of the hyperaccumulator Thlaspi praecox. Reported effects of AMF colonization on plant metal uptake are similarly inconsistent (e.g., Diaz et al 1996, Turnau and Mesjasz-Przybylowicz 2003, Chen et al 2005, Jiang et al 2016.…”

“…This approach is difficult to generalize to field conditions, in which many different plant species, AMF species, and metals interact simultaneously. Indeed, in different systems, these greenhouse studies have found that AMF increase (Chen et al 2005; Orłowska et al 2013), decrease (Abdel Aziz et al 1997; Jiang et al 2016), have mixed effects (Weissenhorn et al 1995; Wang et al 2007), or have no effects (Tonin et al 2001; Lagrange et al 2013) on plant metal uptake. It is difficult to synthesize these disparate results across diverse plant-metal systems, and most of them do not take into account the possibility that soil metals affect plants both directly and indirectly via AMF.…”

Arbuscular mycorrhizal colonization has little consequence for plant heavy metal uptake in contaminated field soils

The factors affecting plant uptake of heavy metals from metalliferous soils are deeply important to the remediation of polluted areas. Arbuscular mycorrhizal fungi (AMF), soil-dwelling fungi that engage in an intimate exchange of nutrients with plant roots, are thought to be involved in plant metal uptake as well. Here, we used a novel field-based approach to investigate the effects of AMF on plant metal uptake from soils in Palmerton, PA, USA contaminated with heavy metals from a nearby zinc smelter. Previous studies often focus on one or two plant species or metals, tend to use highly artificial growing conditions and metal applications, and rarely consider metals’ effects on plants and AMF together. In contrast, we examined both direct and AMF-mediated effects of soil concentrations on plant concentrations of 8–13 metals in five wild plant species sampled across a field site with continuous variation in Zn, Pb, Cd, and Cu contamination. Plant and soil metal concentration profiles were closely matched despite high variability in soil metal concentrations even at small spatial scales. However, we observed few effects of soil metals on AMF colonization, and no effects of AMF colonization on plant metal uptake. Manipulating soil chemistry or plant community composition directly may control landscape-level plant metal uptake more effectively than altering AMF communities. Plant species identities may serve as highly local indicators of soil chemical characteristics.

“…Plants can detect and respond to stresses in various ways that support their nourishment. [34][35][36] Plants not only recognize the previous exposure to stresses but also the mechanisms involved in defense, and again when the same stress exposes, they can adapted consequently. [37] The most obvious effect of unfavourable conditions initially appear at the cellular levels after that, physiological symptoms are observable.…”

Stresses are the prime factor for limiting agricultural productivity. Protracted stress conditions are accountable for the generation of reactive oxygen species (ROS) in various cell compartments. ROS attacks biomolecules and interrupts the regular mechanism of the cell that eventually prompts to cell death. Crops requisite to acclimatize adverse external stress generated by ecological conditions with their native biological mechanisms defeated which their growths as well as productivity endure. Microbes, the supreme natural occupants of diverse environments, have developed intricate physiological and metabolic mechanism to manage with potentially toxic oxygen species that are generated by environmental stresses. Subsequently, the interaction of microbial population with plants is an essential for the ecosystem, and microbes are the natural partners that accommodate in plants to combat with antagonistic environment. Plant microbiome involves intricate mechanisms inside the plant cell. Molecular, physiological as well as biochemical studies support to understand the intricate and integrated cellular processes of plant-microbe interactions. During the incessant stress by increasing environmental variations, it is becoming more essential to characterize and decipher plant-microbe association in relation to defense against environmental challenges.
