The role of soil microbiota in plant stress management, though speculated a lot, is still far from being completely understood. We conducted a greenhouse experiment to examine synergistic impact of plant growth promoting rhizobacterium,Bacillus subtilis(BERA 71), and arbuscular mycorrhizal fungi (AMF) (Claroideoglomus etunicatum;Rhizophagus intraradices; andFunneliformis mosseae) to induce acquired systemic resistance in Talh tree (Acacia gerrardiiBenth.) against adverse impact of salt stress. Compared to the control, the BERA 71 treatment significantly enhanced root colonization intensity by AMF, in both presence and absence of salt. We also found positive synergistic interaction betweenB.subtilisand AMFvis-a-visimprovement in the nutritional value in terms of increase in total lipids, phenols, and fiber content. The AMF and BERA 71 inoculated plants showed increased content of osmoprotectants such as glycine, betaine, and proline, though lipid peroxidation was reduced probably as a mechanism of salt tolerance. Furthermore, the application of bioinoculants to Talh tree turned out to be potentially beneficial in ameliorating the deleterious impact of salinity on plant metabolism, probably by modulating the osmoregulatory system (glycine betaine, proline, and phenols) and antioxidant enzymes system (SOD, CAT, POD, GR, APX, DHAR, MDAHR, and GSNOR).

Positive Effect

The influence of the mycorrhizal infection by G. mosseae (Nicol. et Gerd.) Gerd et Trappe on the growth of Medicago sativa L. plants under different level of soil pollution with heavy metals (Zn, Pb, Cd, Cu) and arsenicum was studied. It was established the strongly increase of the growth and shoot biomass of mycorrhizal plants. The positive effect of mycorrhization on the growth of alfalfa plants was greater in the soils with the higher level of soil pollution with heavy metals and arsenicum.
