“…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 nutrition for N has also been improved by the application of some fungal inoculants. Arbuscular mycorrhizal fungi that form associations with more than 80 % of plants including most crops have also been identified as a probable N mobilizer for plants (Hodge and Storer 2015;Veresoglou et al 2012). However, the contribution of arbuscular mycorrhizal fungi to plant N uptake varies widely and the reasons for the variability are still unclear and may likely be resolved by the application of genomics and metabolomics technology (Hodge and Storer 2015).…”

The role of arbuscular mycorrhizal fungi in plant P nutrition and soil structure improvement is well established, and the prospect of involving it in the N nutrition of crops will be a giant stride in tackling soil degradation problems through the use of microbial inoculants.…”

“…Their review discusses the potential of various techniques, including the use of transparent soil, to provide better understanding of root-soil interactions. Other reviews in this field deal with modelling of rhizosphere and plant-soil interactions (Hinsinger et al 2011;Dunbabin et al 2013), mycorrhizae (Treseder 2013), mycorrhizal nitrogen uptake (Hodge and Storer 2015), and transport processes in porous media (Wildenschild and Sheppard 2013). Finally, there is a collection of articles published in edited books (Anderson and Hopmans 2013;Bengough 2012;Timlin and Ahuja 2013) covering issues related to this review, such as neutron and X-ray imaging.…”

Background Plant-soil interaction is central to human food production and ecosystem function. Thus, it is essential to not only understand, but also to develop predictive mathematical models which can be used to assess how climate and soil management practices will affect these interactions. Scope In this paper we review the current developments in structural and chemical imaging of rhizosphere processes within the context of multiscale mathematical image based modeling. We outline areas that need more research and areas which would benefit from more detailed understanding. Conclusions We conclude that the combination of structural and chemical imaging with modeling is an incredibly powerful tool which is fundamental for understanding how plant roots interact with soil. We emphasize the need for more researchers to be attracted to this area that is so fertile for future discoveries. Finally, model building must go hand in hand with experiments. In particular, there is a real need to integrate rhizosphere structural and chemical imaging with modeling for better understanding of the rhizosphere processes leading to models which explicitly account for pore scale processes.
