“…Aerial biomass was less affected by As than roots in non-inoculated plants as described for rice, wheat [5,7,17], and soybeans [14]. Resembling the findings of other authors [26], inoculated plants were less affected by As. The plant height and number of leaves ( Figure 2) showed a similar behavior to aerial biomass.…”

“…These findings are consistent with the general proposition that the restriction of As uptake by plants seems to be a strategy of AM fungi obtained from non-contaminated areas [26]. Due to the decrease in As concentration in roots of inoculated plants in the present experiment, results disagree with the idea that AM fungi reduce As translocation from inoculated roots.…”

“…However, mycorrhizae altered this relation since AM fungi inoculation reduced to one third the As accumulated in roots, as well as the As accumulated in leaves (although less markedly). Other authors have recorded lower As concentrations on mycorrhized plants such as maize [29], tomato [31], lentil [35], clover [36], sunflower [37], rye grass and white clover [38], and plants growing on As-contaminated areas [26]. They have stated different hypotheses: (i) mycorrhizal inoculation improves the plant yield and causes a dilution effect in the As concentration; (ii) AM fungi hyphae exhibit a great variety of free groups such as hydroxyl, carboxyl, and amino acids, which could bind to As, retaining it in the fungal tissues and reducing the As intake by roots.…”

Arsenic (As) in soils causes several detrimental effects, including death. Arsenic toxicity in soybean plants (Glycine max L.) has been little studied. Arbuscular mycorrhiza (AM) increase the tolerance of host plants to abiotic stress, like As. We investigated the effects of AM fungi on soybean grown in As-contaminated soils. A pot experiment was carried out in a glasshouse, at random with five replications. We applied three levels of As (0, 25, and 50 mg As kg −1 ), inoculated and non-inoculated with the AM fungus Rhizophagus intraradices (N.C. Schenck & G.S. Sm.) C. Walker & A. Schüßler. Plant parameters and mycorrhizal colonization were measured. Arsenic in the substrate, roots, and leaves was quantified. Arsenic negatively affected the AM percentage of spore germination and hyphal length. As also affected soybean plants negatively: an extreme treatment caused a reduction of more than 77.47% in aerial biomass, 68.19% in plant height, 78.35% in number of leaves, and 44.96% reduction in root length, and delayed the phenological evolution. Mycorrhizal inoculation improved all of these parameters, and decreased plant As accumulation (from 7.8 mg As kg ). AM inoculation showed potential to reduce As toxicity in contaminated areas. The AM fungi decreased As concentration in plants following different ways: dilution effect, less As intake by roots, and improving soybean tolerance to As.

“…Several studies have reported that mycorrhiza colonized plants show improved growth under various stresses like salinity (Evelin et al 2009;Kaya et al 2009;Ardakani et al 2011;Evelin and Kapoor 2014), drought (Tian et al 2013;Li et al 2014) and heavy metal toxicity (Schutzendubel and Polle 2002;Luo et al 2014). In case of As, AMF inoculated Plantago lanceolata plants were found to have higher biomass and lower As in roots as compared to non-inoculated plants (Orlowska et al 2012). Inoculation of AMF enhanced grain yield of upland rice without increasing grain As concentrations in Asspiked soils .…”

The intimate association between the arbuscular mycorrhizal fungi and host plants helps the latter in phosphate acquisition in exchange of carbohydrates and in enhanced stress tolerance. Similarly, the ubiquitous 14-3-3 protein family is known to be a major regulator of plant metabolism and stress responses. However, the involvement of mycorrhiza and plant 14-3-3 proteins interaction in plant response to environmental stimuli, such as arsenic (As) stress, is yet unknown. In this study, we analysed the impact of the As stress on the expression profile of 14-3-3 genes in the shoot of mycorrhiza colonized rice (Oryza sativa) plants. Ten day old rice seedlings were kept for 45 days for mycorrhizal colonisation (10 g inoculum per 120 g soilrite) and were then subjected to 12.5 lM arsenate [As(V)] exposure for 1 and 3 days, in hydroponics. Arsenate stress resulted in significant change in expression of 14-3-3 protein genes in non-colonized and mycorrhiza colonized rice plants which indicated As mediated effects on 14-3-3 proteins as well as interactive impact of mycorrhiza colonization. Indeed, mycorrhiza colonization itself induced up-regulation of all 14-3-3 genes in the absence of As stress. The results thus indicate that 14-3-3 proteins might be involved in As stress signalling and the mycorrhiza induced As stress response of the rice plants.

“…Smith et al (2010), Christophersen et al (2012), and He and Lilleskov (2014) compared the root and mycorrhizal Pi/arsenate (As(V)) uptake pathways and confirmed the important role of AMF in plant resistance to As contamination. Moreover, As-tolerant fungi may provide additional benefits to host plants over non-tolerant fungi (Orlowska et al 2012). As-tolerant mycorrhizal fungi have also been reported to enhance arsenite (As(III)) exudation and reduce As(V) uptake in an As-contaminated environment and thus confer enhanced As tolerance on host plants (Gonzalez-Chavez et al 2002).…”

A pot experiment was carried out to investigate the effects of water management and mycorrhizal inoculation on arsenic (As) uptake by two rice varieties, the As-resistant BRRI dhan 47 (B47) and As-sensitive BRRI dhan 29 (B29). Grain As concentration of B47 plants was significantly lower than that of B29, and grain As concentration of B47 was higher under flooding conditions than that under aerobic conditions. In general, mycorrhizal inoculation (Rhizophagus irregularis) had no significant effect on grain As concentrations, but decreased the proportion of inorganic arsenic (iAs) in grains of B47. The proportion of dimethylarsinic acid (DMA) in the total grain As was dramatically higher under flooding conditions. Results demonstrate that rice variety selection and appropriate water management along with mycorrhizal inoculation could be practical countermeasures to As accumulation and toxicity in rice grains, thus reducing health risks of As exposure in rice diets.
