“…Most of the plants form symbiotic associations with the arbuscular mycorrhizal fungi (AMF). AMF improves host plant growth by enhancing the rhizospheric soil characteristics (Asghari et al 2005;Ahanger et al 2014a;Hodge & Storer 2015) and enhances mobilization and uptake of several essential elements by modifying root architecture (Wu et al 2010;Ahanger et al 2014a;Hameed et al 2014;Hodge & Storer 2015). AMF has been reported to alleviate the salt stress in plants through various mechanisms.…”

Present experiments were conducted to assess the response of Panicum turgidum to salinity and possible role of arbuscular mycorrhizal fungi (AMF) in enhancing the salt tolerance. The activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), glutathione reductase (GR) and compatible solutes were increased by salt stress and were further enhanced by AMF inoculation. Hydrogen peroxide and malonaldehyde content increased in salt-stressed plants while a reduction was observed due to AMF inoculation. Salt-stressed plants showed higher activities of pyruvate orthophosphate dikinase (PPDK), phosphoenolpyruvate carboxylase (PEPC) and malate dehydrogenase as compared to control and AMF-inoculated plants. Salt stress caused significant decrease in phosphorous, potassium and calcium uptake but an increase in sodium uptake was observed. AMF alleviate salinityinduced negative impact on the plant growth and nutrient uptake by reducing the oxidative damage through strengthening of the antioxidant system.

“…Plant associated with microorganisms are of two general types, those forming a symbiotic relationship with the plant and those that are free-living in the soil and root (Hameed et al, 2014;Ahanger et al, 2014). Arbuscular mycorrhizal fungi (AMF) are ubiquitous and have proved to posses the potential to improve soil structure and plant growth under normal as well as stressful environments (Tang et al, 2009;Navarro et al, 2013).…”

“…AMF colonization has been reported to enhance plant growth and vigour (Ahanger et al, 2014;Alqarawi et al, 2014a;Hashem et al, 2014b). AMF colonization brings morphological, nutritional and physiological changes and has also been reported to enhance resistance of plants to abiotic stresses (Hameed et al, 2014). AMF modifies root architecture so that roots explore much water and nutrients (Aroca et al, 2013;Ahanger et al, 2014;Wu et al, 2014).…”

The aim of present study was to examine the effect of arbuscular mycorrhizal fungi (AMF) on the growth, lipid peroxidation, antioxidant enzyme activity and some key physio-biochemical attributes in cowpea (Vigna unguiculata [L.] Walp.) subjected to salt stress. Salt stress (200 mM NaCl) reduced growth, biomass, relative water content and chlorophyll pigment content in cowpea leaves. AMF ameliorated the negative impact of salinity on the growth parameters studied. The activity of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), peroxidase (POD) and glutathione reductase (GR) enhanced under salt stress and AMF inoculation further enhanced their activity, thus strengthening the plant's defense system. Proline content increased in salt stressed plants as well as AMF-inoculated plants providing efficient protection against salt stress. Besides this AMF also increased uptake of mineral elements which have direct impact on the osmoregulation of the plants. The present study shows that AMF possesses the potential to enhance salt tolerance of cowpea.

“…Arbuscular mycorrhizas (AM) are pervasive and they are found in 80% of vascular plant families in existence today and fungi belonging to the order glomeromycota. AM have been shown to promote plant growth (Hameed et al, 2014), enhance nutrient uptake such as nitrogen, phosphorus, magnesium, and micronutrients from the soil (Evelin et al, 2012), improve soil structure, and also able to enhance plant tolerance under different stresses such as drought and salinity (Wu et al, 2014). Plants treated with AM fungi have shown to have enhanced the growth and yield, and maintains the osmotic and ionic balance to a normal level so that plants will thrive well under these stress conditions (Hameed et al, 2014).…”

A pot experiment was carried out in the nethouse of Soil Science Division, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during 2014-2015 through 2015-2016. The design of the experiment was factorial randomized completely block design with 4 replications. The objectives of the study were to evaluate the potential of Arbuscular mycorrhization (AM) on the germination, yield and yield attributes of lentil treated with different concentration of sodium chloride (NaCl). Five NaCl treatments (0, 1, 2, 3 and 4%) possessed NaCl level as the first factor that were treated with soils before sowing of lentil seeds overriding or pivotal pulse crop in Bangladesh. The second factor consists of mycorrhizal and non-mycorrhizal treatments. Mycorrhizal plants showed better performance in terms of germination %, yield and yield contributing characters than non-mycorrhizal plants. With increasing NaCl concentration germination %, yield and yield contributing characters in the rhizosphere soil, decreased significantly (p<0.01). Interaction effects of mycorrhizal inoculation and NaCl on germination %, growth and yield of lentil were appeared to be statistically nonsignificant. The highest germination (96.25% in 2014-2015 and 92.50% in 2015-2016), seed yield (6.45 g pot -1 in 2014-2015 and 5.89 g pot -1 in 2015-2016), and stover yield (9.55 g pot -1 in 2014-2015 and 8.58 g pot -1 in 2015-2016) was found in NaCl 0% + AM treatment. The lowest germination %, seed yield and stover yield was found in NaCl 4% treatment. Mycorrhizal inoculation increased seed yield on an average by 31.85% during 2014-2015 and 63.71% during 2015-2016, and increased stover yield on an average by 48.56% during 2014-2015 and 63.55% during 2015-2016 over non-mycorrhizal inoculation. Therefore, it can be concluded that mycorrhizal inoculation increases germination %, growth and yield of lentil over non-mycorrhizal inoculation.
