“…The increased antioxidant activity is likely related to the increase of total levels of phenolic compounds (Degáspari and Waszczynskyj 2004), molecules that are known for their antioxidant power. In other studies, the arbuscular mycorrhizal symbiosis has also been found to increase the total antioxidant activity (Ceccarelli et al 2010;Hernández-Ortega et al 2012).…”

Ingazeira (Inga vera Willd.), a plant native to Brazil is commonly used by Brazilians for its medicinal properties and the value of its wood. Various plants with therapeutic properties and economic importance benefit from mycorrhizal inoculation, which produces larger quantities of therapeutic compounds. However, the effects of mycorrhizal inoculation on ingazeira have not yet been studied. The objective of this paper is to evaluate the effectiveness of arbuscular mycorrhizal fungi (AMF) on the growth of seedlings and production of primary and secondary metabolites, and to determine the total foliar antioxidant activity in ingazeira seedlings. Soilinoculum was applied to the root region of ingazeira plantlets, which were transplanted into sacs containing 1.2 kg of soil and 10 %

“…AMF are ubiquitous terrestrial symbionts involving functioning parts of plants living in mutualistic association with the fungi (Meier et al, 2012). Symbiotic mycorrhizal associations can increase the efficiency of phytoremediation due to improvements in the uptake and delivery of nutrients to the plant and in tolerance to metal toxicity (Bissonnette et al, 2010;Cornejo et al, 2013;Hernandez-Ortega et al, 2012). For example, the nonpathogenic Fusarium fungus was able to increase S. alfredii root system function, metal availability and accumulation, plant biomass, and thus Zn phytoextraction efficiency (Zhang et al, 2012a).…”

“…The arbuscular mycorrhizal fungi (AMF) are universal soil microbes constituting an integral component of terrestrial ecosystems, forming symbiotic associations with plant root systems of over 80% of all terrestrial plant species, including most angiosperms, some gymnosperms, pteridophytes, lycopods, and mosses 14,15 . AMF are involved in the most widely distributed root symbioses among the soil microflora, forming associations with most ter-restrial flowering plants 16 , improving their growth conditions, and alleviating toxicity of environmental stresses such as diesel contamination 17 . AMF are developed inside roots and within the soil by forming extensive extraradical mycelium nets which help the plant to extract mineral nutrients and water from the soil.…”

A pot experiment was conducted to study the effects of Glomus mosseae and Glomus versiforme on the ascorbate-glutathione cycle metabolism and caesium enrichment in roots and leaves of Sorghum halepense. The results showed that inoculated G. mosseae and G. versiforme significantly increased the concentrations of ascorbate (AsA) and reduced glutathione (GSH), the ratios of AsA/DHA (dehydroascorbate) and GSH/GSSG (oxidized glutathione) in roots and leaves of S. halepense in Cs contaminated soil. Additionally, the inoculated arbuscular mycorrhizal fungi increased the antioxidant enzyme activities of the ascorbate-glutathione cycle, with the best efficiency provided by G. mosseae. The activities of antioxidant enzymes (ascorbate peroxidase, APX, EC 1.11.1.11; dehydroascorbate reductase, DHAR, EC 1.8.5.1; and glutathione reductase, glutathione reductase (GR), EC 1.8.1.7) in the roots were, respectively, 4.7, 3.6, and 2.3 times higher than those in non-inoculated roots, and the activities of DHAR was 1.7 times higher than that in non-inoculated leaves. However, G. versiforme increased the activity of monodehydroascorbate reductase (MDHAR, EC 1.6.5.4) 2.39 U/g fresh weight, and the activities of APX and GR were 6.8 and 1.4 times higher than for nonmycorrhizal plants. G. versiforme also increased the accumulation of caesium in roots and leaves but to a lesser extent than G. mosseae, and with a positive effect on translocation. Thus arbuscular mycorrhizal fungi promotes efficient operation of ascorbate-glutathione cycle in the roots and leaves of S. halepense, enhancing its tolerance to Cs stress.
