“…We found that approximately 60% of the total 20 chenopod plant species were colonized by AM fungi, being consistent with previous observations of AM structures in the root systems of other chenopod species (Hirrel et al, 1978;Allen, 1983;Allen and Allen, 1990;Sigüenza et al, 1996;Asghari et al, 2005;Plenchette and Duponnois, 2005;Püschel et al, 2007;Aleman and Tiver, 2010;Zhang et al, 2012). In previous studies, arbuscule formed within root cortical cells was often considered as one of the most important characteristics of mycorrhizal plants (Smith and Read, 2008) and the arbuscule structure was observed in the root of chenopod species in South Australia (Asghari et al, 2005;Aleman and Tiver, 2010). Moreover, arbuscule is often considered as a primary functional interface of the symbiosis and is important to carbon (C) and phosphorus (P) exchanges in the root (Smith and Read, 2008;Selosse and Rousset, 2011).…”

“…Some species in the family Chenopodiaceae are rather tolerant to high salinity and/or to drought stress and/or to soil-nutrient deficiencies and many of them are of great economic and ecological values (Glenn et al, 1991). An increasing number of studies have found that many chenopods can be colonized by AM fungi (Allen, 1983;Allen and Allen, 1990;Sigüenza et al, 1996;Aguilera et al, 1998;Shi et al, 2006;Wilde et al, 2009;Aleman and Tiver, 2010;Zhang et al, 2012). Several studies have further shown that AM fungi can improve the growth of the chenopod species Atriplex canescens (Williams et al, 1974), Arthrocnemum indicum and Suaeda maritime (Sengupta and Chaudhuri, 1990), Atriplex nummularia (Asghari et al, 2005;Plenchette and Duponnois, 2005) and Ceratocarpus arenarius (Zhang et al, 2012).…”

Chenopodiaceae is one of the most important families in arid and saline environments. Several studies have observed the mycorrhizal structure in Chenopodiaceae plants (i.e., chenopods), but the mycorrhizal colonization status of chenopods in saline habitats and the influencing factors are still not well understood. The mycorrhizal colonization of twenty chenopod species in three different saline habitats (a saline alkaline meadow in the Songnen Plain of northeastern China, a saline desert in the Junggar Basin of northwestern China, and a saline alpine meadow in the Tibetan Plateau of western China) and the chenopod-associated environmental factors (including soil moisture, soil available phosphorous (P) concentration, pH, and salt content) were analyzed. Our results showed that approximately 60% of the studied chenopods were colonized by arbuscular mycorrhizal (AM) fungi with a colonization percentage ranging from 5% to 33%. Structural analysis of mycorrhizal association indicated that vesicles were quite common, while arbuscules and hyphal coils were relatively rare. In addition, a positive correlation between mycorrhizal colonization rate and soil electrical conductivity (r=0.920, P<0.01) and two negative correlations of mycorrhizal colonization rates with soil moisture (r=-0.818, P<0.01) and the soil available P concentration (r=-0.876, P<0.01) confirmed that mycorrhizal colonization rate in the roots of chenopods was environment-dependent.

“…arbuscules or vesicles (Hirrel et al, 1978;Brundrett, 2002;Smith and Read, 2008). However, a growing number of studies have now found that many Amaranthaceae species can be colonized by AMF in Port Wakefield, South Australia (Aleman and Tiver, 2010), in Simpson Desert, Australia (O'Connor et al, 2001), and in Junggar Basin, China (Shi et al, 2006;Zhang et al, 2012), meanwhile, AMF can improve their growth. For instance, Williams et al (1974) first observed that the growth of Atriplex canescens inoculated with Glomus mosseae increased in sterilized soil.…”

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.

“…Smith and Read (2008) reported that plant species belonging to the Chenopodiaceae are non-mycorrhizal plants and arbuscules very rarely to observe in their roots. However, many recent investigations including microscopic characterization, demonstrates that many chenopods can be well colonized by AMF natively and artificially in pot experiments (Wilde et al, 2009, Aleman and Tiver, 2010, Zhang et al, 2012). The aim of this study was to evaluate cadmium stress-induced effects on the growth, lipid peroxidation and antioxidant activity in B. indica and the ameliorative role of arbuscular mycorrhizal fungi (AMF) and calcium applications.…”

The aim of this study was to evaluate cadmium stress induced changes in the growth, lipid peroxidation and antioxidant activity of Bassia indica associated with arbuscular mycorrhizal fungi (AMF) and their amelioration by calcium application. Cadmium stress can cause alterations in the physiological and biochemical processes in plants. A calcium application combined with an AMF treatment resulted in the reduction of lipid peroxidation and the production of hydrogen peroxide, thereby mediating the mitigation of cadmium induced oxidative stress. The activity of antioxidant enzymes increased with cadmium application, whereas AMF inoculation combined with a calcium application further enhanced their activity. An increase in the content of non-enzymatic antioxidants such as ascorbate, reduced glutathione (GSH), oxidized glutathione (GSSG) and S-nitrosoglutathione (GSNO) in AMF-inoculated and calcium-treated plants further suggests their role in strengthening the antioxidant defense system that results in maintained growth. The application of calcium combined with the AMF treatment caused a significant reduction in lipid peroxidation and in the production of hydrogen peroxide, thereby mediating the mitigation of the cadmium induced oxidative stress. Increased proline accumulation was clearly evident in stressed plants, and the calcium application as well as the AMF inoculation further induced proline synthesis, thereby providing efficient protection against cadmium stress by increasing the maintenance of the systemic resistance criteria.
