“…Various abiotic stress factors and AM can have interactive effects, whereby the symbiosis often mediates phytoprotection against the stressors [17,[39][40][41]. For example, low temperature slows down plant physiology, but AM can improve the tolerance of plants to this stress [40].…”

“…A growing interest in the potential of AM to increase the contents of secondary metabolites with health promoting activities led to intensified research on medicinal plants [15][16][17], indeed revealing positive effects of AM on leaf concentrations of isoprenoids, phenolic compounds, gallic acid, and anthraquinone derivatives ( Figure 2) [18-21,22 ,23]. Apart from medicinal plants, AM-mediated modifications of secondary metabolite concentrations were found for phenolic acids, iridoid glycosides and various alkaloids ( Figure 2) (e.g., [24,25 ,26 ]).…”

“…AMF have been found to stimulate growth, improve resistance to pathogens, heavy metals and salinity, and influence the level of secondary metabolites in plants (Smith and Read 2008). The use of these symbiotic soil microorganisms has therefore been proposed for medicinal plant species (Ceccarelli et al 2010;Copetta et al 2006;Kapoor et al 2002aKapoor et al , b, 2007Khaosaad et al 2006;Rozpądek et al 2014;Sbrana et al 2014;Toussaint 2007;Toussaint et al 2007Toussaint et al , 2008Zubek et al 2010Zubek et al , 2011Zubek et al , 2012a.…”

Enhanced concentrations of elements and secondary metabolites in Viola tricolor L. induced by arbuscular mycorrhizal fungi

et al. 2015

Background and Aims Viola tricolor L. (heartsease, wild pansy) is a valuable medicinal plant obtained for pharmaceutical purposes by cultivation. Given that the species is usually strongly colonized by arbuscular mycorrhizal fungi (AMF), we tested in a pot experiment whether these microorganisms were able to influence V. tricolor mass, vitality, and the concentrations of selected elements, phenolic acids and flavonoids. Methods The following treatments were prepared: (1) control: sterile soil without AMF inoculation; (2) Rhizophagus irregularis BEG144; (3) Funneliformis mosseae BEG12; and (4) both isolates. Using a combination of physiological, phytochemical and biophysical methods, we evaluated the effects of these AMF on the performance of heartsease. Results The intensity of mycorrhizal colonization and arbuscule formation was higher when F. mosseae and R. irregularis were introduced separately than when both isolates were present. None of the AMF treatments had an impact either on V. tricolor vitality as expressed by photosynthetic performance index (PI) or on its shoot and root mass. However, in general, a negative correlation was found between the extent of mycorrhizal colonization and shoot mass. We found AMF species specificities in their influence on element, phenolic acid and flavonoid concentrations. Viola tricolor showed no response to F. mosseae. The plants inoculated with R. irregularis had higher concentrations of P, Zn, Mg, and Ca, as well as p-hydroxybenzoic acid and rutin, in comparison to control. Dual AMF species inoculation increased concentrations of Cu, Mg and rutin. Conclusions The enhanced production of secondary metabolites in V. tricolor shoots may be due to improved mineral nutrition by AMF and/or a result of general plant defense reaction to fungal colonization. The tendency towards biomass decrease in AMF treatments could be explained by the allocation of plant carbon both to the maintenance of symbionts and enhanced production of secondary compounds.

“…For example, higher levels of antioxidant enzyme activities were observed in leaves of tomato plants colonized by Glomus mosseae (Abdel Latef and Chaoxing 2011). According to Rozpądek et al (2014), SOD activity measured in Cichorium intybus L. significantly increased in AMF inoculated plants, compared to non-inoculated plants. Estrada et al (2013) also found that AMF symbiosis induced SOD and CAT activities of maize shoots and roots, emphasizing that the degree of induction depended on the AMF species.…”

Mycorrhizal fungi, algae and cyanobacteria are some of the most important soil microorganisms and major components of a sustainable soil-plant system. This study presents for the first time evidence of the impact of green alga and cyanobacterium solely and in combination with arbuscular mycorrhizal fungi (AMF) on plant-antioxidant capacity. In order to provide a better understanding of the impact of AMF and soil microalgae on Ocimum basilicum L. performance, changes in the pattern and activity of the main antioxidant enzymes (AOEs), esterases and non-enzymatic antioxidants including phenols, flavonoids, ascorbate, and α-tocopherols were evaluated. The targeted inoculation of O. basilicum with AMF or algae (alone and in combination) enhanced the antioxidant capacity of the plants and the degree of stimulation varied depending on the treatment. Plants in symbiosis with AMF exhibited the highest antioxidant potential as was indicated by the enhanced functions of all studied leaf AOEs: 1.5-, 2-and more than 10-fold rises of superoxide dismutase (SOD), glutathione-S-transferase (GST) and glutathione reductase (GR), respectively. The greatest increase in the total esterase activity and concentration of phenols, flavonoids and ascorbate was marked in the plants with simultaneous inoculation of mycorrhizal fungi and the green algae. 2,2-diphenyl-1-pycril-hydrazyl (DPPH) free radical scavenging method and ferric reducing antioxidant power (FRAP) assay proved the increased plant antioxidant capacity after co-colonization of green algae and mycorrhizae.
