“…By contrast, the predictions for the 'Metal-Binding' 43 hypothesis are that plant HM uptake is decreased whereas HM phytotoxicity is reached at higher 44 soil-HM concentrations in AM than non-AM plants. We have determined in a previous meta-45 analysis (Audet & Charest, 2006b) that there is an important compromise between plant growth 46 and HM uptake specifically relating to HM tolerance versus production of biomass under soil- 47 HM conditions.…”

“…All these factors, alone or in combination, can influence metal mobility or availability. Nevertheless, the role of AM fungi in the uptake and in the transfer of heavy metals to the plant is still poorly understood and literature results are conflicting (Citterio et al 2005). Many fungi can survive and grow in high concentrations of toxic metals (Gadd 1993).…”

The biotransformation of metals is an exciting, developing strategy to treat metal contamination, especially in environments that are not accessible to other remediation technologies. However, our ability to benefit from these strategies hinges on our ability to monitor these transformations in the environment. That's why remediation of contaminated sediments and soil requires detailed in situ characterization of the speciation of the toxic substances and their transformations with respect to time and spatial distribution. The present paper gives an overview of the literature regarding research performed in the laboratory as well as in the field.

“…The AM fungi associated with metal-tolerant plants may contribute to the accumulation of heavy metals in roots in a non-toxic form inside hyphal cell walls or complexed into phosphate materials inside the cells (Galli et al, 1995). However, the effect of AM fungi on the uptake of metals by plants is not yet totally clear, with reports finding increased uptake of metals (Tonin et al, 2001;Liao et al, 2003;Whitefield et al, 2004;Citterio et al, 2005), decreased uptake (Weissenhorn et al, 1995, Chen et al, 2003 or no uptake effects (Trotta et al, 2006;Wu et al, 2007). Factors such as the metal element and its availability, plant species, fungal species or strain and differences in mycorrhizal and non-mycorrhizal plant size and P content in experiments may account for different results .…”

-An unprecedented, rapid change in environmental conditions is being observed, which invariably overrules the adaptive capacity of land plants. These environmental changes mainly originate from anthropogenic activities, which have aggravated air and soil pollution, acid precipitation, soil degradation, salinity, contamination of natural and agro-ecosystems with heavy metals such as cadmium (Cd), lead (Pb), mercury (Hg), arsenic (As), global climate change, etc. The restoration of degraded natural habitats using sustainable, low-input cropping systems with the aim of maximizing yields of crop plants is the need of the hour. Thus, incorporation of the natural roles of beneficial microorganisms in maintaining soil fertility and plant productivity is gaining importance and may be an important approach. Symbiotic association of the majority of crop plants with arbuscular mycorrhizal (AM) fungi plays a central role in many microbiological and ecological processes. In mycorrhizal associations, the fungal partner assists its plant host in phosphorus (P) and nitrogen (N) uptake and also some of the relatively immobile trace elements such as zinc (Zn), copper (Cu) and iron (Fe). AM fungi also benefit plants by increasing water uptake, plant resistance and biocontrol of phytopathogens, adaptation to a variety of environmental stresses such as drought, heat, salinity, heavy metal contamination, production of growth hormones and certain enzymes, and even in the uptake of radioactive elements. The establishment of symbiotic association usually involves mutual recognition and a high degree of coordination at the morphological and physiological level, which requires a continuous cellular and molecular dialogue between both the partners. This has led to the identification of the genes, signal transduction pathways and the chemical structures of components relevant to symbiosis; however, scientific knowledge on the physiology and function of these fungi is still limited. This review unfolds our current knowledge on signals and mechanisms in the development of AM symbiosis; the molecular basis of nutrient exchange between AM fungi and host plants; and the role of AM fungi in water uptake, disease protection, alleviation of various abiotic soil stresses and increasing grain production.
