“…Better mineral nutrition, such as P uptake and lower heavy metal uptake and transport, may be the possible mechanisms for the success of mycorrhizal plants growing in soils with excessive levels of metals (Liao et al 2003;Weissenhorn and Leyval 1995;Zhang et al 2005;Ouziad et al 2005). In the present study, under low Cu and Pb treatments, a sharp increase of P uptake in mycorrhizal plants was observed along with an increase in biomass, which suggested that mycorrhiza was beneficial for upland rice in taking up P nutrition and also enhanced its capability against Cu and Pb toxicity.…”

“…Arbuscular mycorrhizal fungi (AMF), a group of special microorganisms connecting the soils and plants directly, play an important role in environmental remediation (Smith and Read 1997;Christie et al 2004;Liao et al 2003). The mycelium of AMF can colonize the roots and form a symbiosis with the roots, termed mycorrhiza (Smith and Read 1997), which offers an effective way for the exchange of nutrient substances between AMF and the plant.…”

“…Despite the significant role that AM fungi play in plant interactions with soil toxic metals and the ubiquity of AM fungi in the soil environment, only recently has progress been made towards understanding the cellular mechanisms utilized by AM fungi to metabolize heavy metals and alleviate their cytotoxicity (Lanfranco et al, 2002). Numerous studies have revealed that AM fungi confer upon plants tolerance against heavy metal stress (Davies et al, 2001;Levyal et al, 2002;Liao et al, 2003). Plant associations with AM fungi are suggested as a potential biological solution to ameliorate plant resistance to metal toxicity and restore fertility of soils polluted by heavy metals such as Cd (Vivas et al, 2005).…”

“…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.

Tolerancia a metales pesados a través del uso de micorrizas arbusculares en plantas cultivadas RESUMENLa simbiosis establecida entre plantas y hongos formadores de micorrizas arbusculares (HFMA) ampliamente distribuida en ecosistemas y agroecosistemas, ha mostrado ser eficiente al disminuir la concentración de metales pesados (MP) en diferentes especies vegetales, constituyéndose en una herramienta potencial para el manejo de plantas cultivadas bajo estas condiciones. La tolerancia a esta toxicidad, puede variar según el metal pesado que se trabaja, la concentración del mismo en el suelo, las especies involucradas (hongo y vegetal) y las condiciones específicas de cada cultivo (bióticas y abióticas). Este artículo hace una revisión sobre los diferentes mecanismos fisiológicos de absorción, asimilación, translocación y acumulación de MP involucrados a nivel celular en la simbiosis, justificando el uso de micorrizas en la mitigación y tolerancia a esta contaminación.
