“…This may owing to the ability of mycorrhiza to increase root surface area to uptake mineral contents and make phosphorus absorpable by plant roots. This result was in agreement with the finding of Pagano et al (2010) who reported that VAM colonization was significantly higher with the inoculated seedlings versus non-inoculated ones (control) and Tazisong et al (2015) who said that Phosphatases are responsible for the hydrolysis of a range of organic P compounds and provide mineral phosphate to the plant. Furthermore, Matias et al (2009) reported that the intensity of VAM colonization was also stimulated by plant growth.…”

Salinity is a devastating environmental stress factor that severely affects plant growth and development. Soil salinity often hinders plant productivity in both natural and agricultural settings. Vesicular Arbuscular mycorrhizal fungal (VAM) symbionts can mediate plant stress responses by enhancing salinity tolerance. Experiments were conducted in a greenhouse at the nursery of the Experimental Station of Forestry and Wood Technology Dept., Faculty of Agriculture, University of Alexandria, Abies region, Alexandria, from June, 2017 to May, 2018 and repeated at the same time in the second season. The obtained results showed that the inoculation with VAM and addition of RP led to enhance the growth significantly, in terms of survival, shoot height, shoot root ratio, root dry weight, shoot dry weight and total dry weight and minerals of the leaves of M. oleifera (N, P and K%) compared with the uninoculated ones. Chlorophyll a of M. oleifera was affected by salinity. Na Cl treatments caused a decrease in chlorophyll a and chlorophyll b content in both seasons. The largest increases in plants nutrient uptake (N, P and K) and decreasing in Na were observed with the VAM+RP treatment. The inoculated seedlings with VAM induced the highest value in Proline content in the first and second seasons compared with the uninoculated ones.The present study concluded that (M. oleifera Lam.) could tolerate salt concentration up to 171.1 mM in the presence of mycorrhiza. It is recommended; however, to inoculate the seedlings with VAM and (1g/kg soil) rock-phosphate application to enhance its growth and mitigate salinity stress.

“…Mycorrhizas also play an important role in biodiversity of plants and ecosystem functions ( Zhao et al, 2017 ; He et al, 2010 ), by influencing plant community diversity and composition ( van der Heijden et al, 1998 ; van der Heijden, 2004 ; Pagano, Cabello & Scotti, 2010 ). Therefore, AMF play a fundamental role in the origin, evolution, distribution, survival, growth, and development of plants and larger ecosystem scale processes ( Liu & Wang, 2003 ; Wang & Qiu, 2006 ; Mcguire et al, 2008 ; Hiiesalu et al, 2014 ).…”

Background Global warming can alter plant productivity, and community composition which has consequences for soil-plant associated microorganisms. Arbuscular mycorrhizal fungi (AMF) are distributed widely and form symbiotic relationships with more than 80% of vascular plants and play a key role in nutrient cycling processes at the ecosystem scale. Methods A simulated warming experiment at multiple elevations (3,000, 3,500, 3,800, and 4,170 m) was conducted utilizing an in-situ open-top chamber (OTC) for exploring the effect of global warming on AMF community structure in the Qinghai-Tibet Plateau (QTP). This region has been identified as one of the most sensitive areas to climatic changes. Soil DNA was extracted and sequenced using next the Mi-Seq platform for diversity profiling. Results AMF richness was higher under the simulated warming chamber, however this only occurred in the elevation of 3,500 m. Warming did not alter other AMF alpha diversity indices (e.g. Shannon, Ace, and Simpson evenness index). Glomus and Acaulospora were the dominate AMF genera as assessed through their relative abundance and occurrence in control and warming treatments at the different elevations. Conclusion Warming changed significantly AMF community. The effects of warming on AMF community structure varied depend on elevations. Moreover, the occurrences of AMF in different genera were also presented the different responses to warming in four elevations.

“…The last authors suggested that the occurrence of mycorrhiza and the density of AMF spores decreased along the succession, and it could be probably due to morphological root traits in fast-growing species that favored the contact with AMF propagules in the soil. Additionally, studies by Pagano et al (2008Pagano et al ( , 2010) also in semiarid fields of Minas Gerais State, showed higher mycorrhizal sporulation in disturbed sites.…”

Glomus was, in general, the most abundant genus followed by Acaulospora, Gigaspora and Scutellospora (always present in intermediates rates). The contribution of Archaeospora was the lowest; however, in some cases it was absent. AMC was higher in plant roots growing in soils from pasture but the lowest AMC was in plant roots from the intermediate area. This could be associated with the soil acidity, Al and H contents of this area which could be toxic to AMF. Mycorrhiza formation and SN appeared to be more related to the physicochemical characteristics of the soil and the host plant development to the soil successional stage. Further studies are needed in order to identify appropriate management strategies for restoration of altered lands in order to contribute to the biodiversity conservation and microbial activity of ecosystems.
