“…Sugars and proline as osmoprotectants, play key roles in accelerating water absorption and keeping the macromolecular structure and the sub cellular membrane under DS (Gomes et al, 2010). Studies showed that mycorrhizal plants exhibited higher sugar concentrations (Wu et al, 2007;Talaat and Shawky, 2014) due to mycorrhizal carbon cools for the fungal development in terms of sucrose cleavages (Franken, 2010) and AMinduced hydrolysis of starch to sugars in metabolic processes (Boldt et al, 2011). Moreover, accumulation of sugars in (2015).…”

Sucrose and proline metabolisms are often associated with drought tolerance of plants. This study was conducted to investigate the effects of two arbuscular mycorrhizal fungi (AMF) species (Funneliformis mosseae and Paraglomus occultum) on root biomass, lateral root number, root sucrose and proline metabolisms in trifoliate orange (Poncirus trifoliata) seedlings under well-watered (WW) or drought stress (DS). All the AMF treatments significantly increased root dry weight, taproot length, and the number of lateral roots in 1 st , 2 nd , and 3 rd class under WW and DS. Mycorrhizal seedlings conferred considerably higher fructose and glucose concentrations but lower sucrose accumulation, regardless of soil water status. Under DS, F. mosseae treatment significantly increased root sucrose synthase (SS, degradative direction) and sucrose phosphate synthase (SPS) activity but deceased root acid invertase (AI) and neutral invertase (NI) activity, and P. occultum inoculation markedly increased root AI, NI, SS, and SPS activities. AMF treatments led to a lower proline accumulation in roots, in company with lower activities of Δ 1 -pyrroline-5-carboxylate synthetase (P5CS), δ-ornithine aminotransferase (OAT), Δ 1 -pyrroline-5-carboxylate reductase (P5CR), and proline dehydrogenase (ProDH) in roots. It appears that the AM symbiosis induced greater root development and sucrose and proline metabolisms to adapt DS.

“…Previous studies have reported that more than 85% of the documented plant species are putative hosts of arbuscular mycorrhizal fungi (AMF) and that those species benefit from the symbiosis in various ways, including increased absorption of water and mineral nutrients (especially phosphorus, the crucial mineral for plant growth and development) and improved biotic and abiotic stress tolerance through multiple complex mechanisms (Daei et al, 2009;Harley and Smith, 1997;Marschner and Dell, 1994;Pozo et al, 2010;Wang and Qiu, 2006). An increase in salinity tolerance was observed in numerous mycorrhizal colonized plants, including crops such as barley and wheat (Rad et al, 2009;Talaat and Shawky, 2014). Nevertheless, such benefits vary depending on the AMF strains selected and the host plant species involved (Gong et al, 2013;Zou and Wu, 2011).…”

Wheat is an important crop, playing inevitable roles in human life, ranging from major food resource to raw material for biofuel. However, due to the dramatically reduced available arable areas and increasingly severe abiotic and biotic stresses, wheat production nowadays faces extreme challenges.. Many approaches have been explored to increase wheat yield including development of new cultivars. One of the most promising approaches is the application of the naturally existent arbuscular mycorrhiza (AM), a mutualistic symbiosis originated over 400 million years ago. AM have long been known to form mutualistic symbiosis with various plants to enhance yield production and to improve stress tolerance, especially drought and salinity. But the benefits vary among AM strains and plant species. Therefore, the objective of the study was to investigate the influence of four AM strains colonized on four selected spring wheat varieties under three salt concentrations (0, 50, 100 mmol/L). The results demonstrated that wheat inoculated with arbuscular mycorrhizal strains Funneliformis mosseae and Rhizoglomusirregulare mitigated yield losses caused by increased salinity stresses as well as strengthened root growth in comparison with non-inoculated plant controls. Salinity stress, however, had non-significant negative effects on most variables, except for grain yield, root surface area and root dry weight, in which a significant decrease was observed in root surface area and root dry weight with the increasing of saline concentration.
