“…). Gigasporaceae may promote heavy metal stress tolerance better than other AMF families because of its extensive hyphal network which could help to chelate more metal ions and reduce their transportation into plant tissues (Chen & Zhao ). However, some caution should be exercised in this regard because our data were extracted from a single article for the Gigasporaceae group.…”

“…Under drought stress, the faster initial colonization of roots by Glomeraceae compared to other AMF families might be important as activators of genes responsible for drought tolerance, such as aquaporins, proline and ABA (Ruiz-Lozano, Porcel & Aroca 2006;Aroca et al 2008).

Summary1. Arbuscular mycorrhizal fungi (AMF) are key regulators of ecosystem processes, yet how their biodiversity works in ecosystems remains poorly understood. 2. We documented the extent to which taxonomic resolution influenced the effect of biodiversity of AMF taxa on plant performance (growth, nutrient uptake and stress tolerance) in a meta-analysis of 902 articles. 3. We found that the effect of biodiversity of AMF taxa depended on taxonomic resolution. Plant performance was positively promoted by AMF family richness, while no effect was found for fungal species richness. In addition, negative effect was found between AMF phylogenetic diversity and plant growth. This pattern can be explained by functional conservatism within AMF families and functional differentiation among AMF families. 4. Synthesis. Conservation of AMF communities to maintain a full complement of ecosystem functions requires the presence of diverse families and not simply diverse species within a family. This finding may be of key importance for the function of ecosystems under various environmental perturbations to which AMF families may respond differently.

“…Concentration of U was significantly increased in the roots of barley (Hordeum vulgare), Chinese brake fern (Pteris vittata) and three leguminous plants (Sesbania rostrata, Sesbania cannabina and Medicago sativa), when inoculated with three Glomus species, but not in their shoots [118,171,173,192]. Inoculation of Astragalus sinicus with G. margarita or G. intraradices was found to reduce the La concentration in both shoots and roots, and could thus be effective in alleviating La toxicity [193]. These findings suggest that potential exists for screening local plant species in combination with their AM fungi, to aid ecological restoration of mine tailings or damaged ecosystems [122,124].…”

The significance of mycorrhizas (fungal roots in 90% of land plants) in plant nutrient acquisition and growth, element biogeochemical cycling and maintaining of terrestrial ecosystem structures has been globally established for more than 120 years. Great progress in mycorrhizal research in the past 60 years (1950-2009, 1981-2009 in particular) has also been made across China, particularly in the mainland, Hong Kong and Taiwan. For instance, a total of 20 new and approximately 120 records of arbuscular mycorrhizal (AM) fungal species, 30 new and approximately 800 records of ectomycorrhizal (EM) fungal species, a dozen of new and approximately 100 records of orchid mycorrhizal (OM) fungal species have been isolated by morphological observation and/or molecular identification in China since the 1950s. Great accomplishment has also been made in the following area, including fungal species richness and genetic structure, relationships between species composition and plant taxa, effects of mycorrhizal fungi on plant nutrient uptake and growth, resistances to pathogens and interactions with other soil microorganisms, potential of mycorrhizal fungi in phytoremediation and/or land reclamation, alterations of enzymatic activities in mycorrhizal plants, and elevated CO(2) and O(3) on root colonization and species diversity. Unfortunately, the international community cannot easily appreciate almost all Chinese mycorrhizal studies since the vast majority of them have been published in Chinese and/or in China-based journals. The aim of this review is to make a comprehensive exposure of the past and present China's major mycorrhizal research to the whole world, and then to suggest potential directions for the enhancement of future mycorrhizal research within and/or between the Chinese and international mycorrhizal community.

“…Application of higher La doses [5 mg kg -1 (soil)] decreases activity of succinate dehydrogenase (SDH) and alkaline phosphatase (ALP) in fungal mycelium. These two enzymes are considered as an indicator of AM fungi colonization (Chen and Zhao 2007) Treatment with AM fungi significantly increases N, P, and K content in shoots and roots of Astragalus sinicus and growth of Zea mays and Sorghum bicolor in soil enriched with REE. Dry masses of the investigated plants increase by 211 to 387% in shoots and roots compared with the non-inoculated treatment Zhao 2009, Guo et al 2013).…”

Since 1960, the positive effects of rare earth elements (REE) on crop physiology have been observed, and support for photosynthesis, biomass accumulation, secondary metabolites, or enzymes has been reported in 40% of studies. A higher content of chlorophylls a and b as well as carotenoids have been found along with an increased efficiency of photosystem II photochemistry and electron transfer rates. An increased activity of a key photosynthetic enzyme was also found in several plants growing in soil with a higher content of REE. An appropriate amount of REE also activates the antioxidant activity of peroxidase, superoxide dismutase, and catalase. These enzymes, together with a higher content of flavonoids and carotenoids, increase the resistance of plants to oxidative stress caused by different abiotic stresses. The positive effect of REE on biomass accumulation was also confirmed, but their affection on mycorrhizal symbiosis remains ambiguous. On the other hand, an excess of REE leads to damage to plants including the chloroplast ultrastructure. Therefore, the positive and negative effects of REE remain controversial, and the mechanisms of effects of REE in plants remain poorly understood. In addition to physiological processes, the absorption, bioavailability, and translocation of REE in plants as well as their possible ecotoxicology and hyperaccumulation are discussed in this review.
