“…This implies that the enhancement of SOD and POD scavenge reactive oxygen species (ROS) to protect S. physophora from cellular oxidative damage, which is an important protective mechanism against cellular oxidative damage under salt stress (Ahmad et al, 2012). The inoculation of the AMF significantly improved the POD activity of S. physophora, which is consistent with previous studies on Ephedra aphylla (Alqarawi et al, 2014), tomatoes (He et al, 2007), wheat (Talaat and Shawky, 2014) and cowpeas (Abeer et al, 2015). Moreover, the AMF also increased the activity of SOD in the leaves of S. physophora, which corresponds with previous studies (Wu, 2011;Li et al, 2012).…”

“…The possible reasons are that AMF can help plants uptake water (Porcel et al, 2003) and nutrients (Kaya et al, 2009) from the soil and can decrease the concentration of toxic ions caused by high salt in the soil (Al-Karaki et al, 2001;Mohammad et al, 2003). Moreover, AMF have been shown to increase the activities of antioxidative enzymes (He et al, 2007) and produce plant growth hormones (Iqbal and Ashraf, 2013) that have beneficial effects on plant growth under salt stress.…”

Arbuscular mycorrhizal fungi (AMF) play a key role in plant growth and survival; however, the influence of AMF on the growth and production of Suaedoideae species is still not well understood. The object of this study was to understand the mechanism of AMF that affects the growth of Suaedoideae species under different saline conditions. The result showed that the Suaedoideae species Suaeda physophora was colonized by the AMF species Glomus etunicatum (Ge) and Glomus mosseae (Gm). AMF significantly increased the activities of superoxide dismutase (SOD) and peroxidase (POD) in S. physophora and reduced the concentrations of malondialdehyde (MDA) and H 2 O 2 in the leaves of S. physophora under salt stress. AMF also improved the aboveground biomass of S. physophora and significantly increased its seed numbers. Moreover, AMF increased the aboveground phosphorus (P) content of S. physophora. No significant difference between the effect of AMF species Ge and Gm on S. physophora growth was observed. These results suggest that AMF can increase the salt resistance of the Suaedoideae species S. physophora by increasing SOD and POD activities, reducing MDA and H 2 O 2 concentrations and increasing P uptake. The results highlight that AMF might play an important role in S. physophora growth and population survival under harsh salt conditions.

“…Less electrolyte leakage in mycorrhizae treated test plants may be correlated with higher electrolyte concentration in AM plants and this helps to maintain membrane stability (Garg and Manchanda, 2008). Mycorrhization in host plants is responsible for lowering electrolyte leakage at 2.10 to 8.26 dS/m soil salinity stress and this finding is in agreement with the other report (He et al, 2007).…”

Symbiotic association between arbuscular mycorrhizal (AM) species and host plant roots improves plant growth and protects them from several abiotic stress factors. In the present study, the effect of Glomus mosseae and Glomus fasciculatum as an individual inoculation and in combination was studied on two legumes (Glycine max and Cyamopsis tetragonoloba) under soil salinity stress gradient [1.04 (control) to 8.26 dS/m]. Individual and co-inoculation of both the AM fungi alleviated adverse salt effect, with improvement in plant dry weight matter and biochemical parameters. However, these two isolates worked better in combination with respect to higher accumulation of soluble carbohydrate, reducing sugar, protein, proline concentration etc. C. tetragonoloba showed better response as compared to G. max in relation to improvement in nutritional profile under salt stress after AM treatment. As compared to non-mycorrhizal counterparts, co-inoculation with G. mosseae and G. fasciculatum in C. tetragonoloba enhanced total chlorophyll (14.83% at soil salinity of 3.78 dS/m), soluble carbohydrate (17.26% at soil salinity of 5.94 dS/m), proline (8.79% at soil salinity of 3.78 dS/m) while exposed to different soil salinity levels. Also, co-colonization with both the isolates showed more root colonization (%) and may be responsible for the better effect in salt stress alleviation. Electrolyte leakage of mycorrhizal plants was lowered at soil salinity gradient of 2.10 to 8.26 dS/m and hence, maintained membrane stability. These two isolates can be utilized as bio-inoculant in alleviation of adverse salt effect in soil in association with the two test legume plants.

“…The ANOVA revealed that the percentage of colonization was significantly lower in the salt treatment (pϽ0.001) (Table 1), which indicates that the influence on colonization was stronger in the environment (saline or nonsaline) than in the transformation with the mangrin gene. Some researchers reported that high salt concentration significantly lowered the levels of root colonization by AM fungi (Aliasgharzadeh et al 2001;He et al 2007;Juniper and Abbott 1993). Results from this study corroborate those of other reports, which found no influence on mycorrhizal colonization in transgenic plants (Knox et al 2008;Powell et al 2007).…”
