cortex (Bücking et al., 2012). Our studysuggests that in ultramafic soils, ECM helped the plant in findingdeficient elements such as K and Ca and regulated the excess supplyof Mg.
Role of ECM in metal toleranceIn this study, we demonstrated that an ultramafic ecotype of P.albus isolates could improve plant metal tolerance on ultramaficsubstrate when metals were present at high concentration in thesoil. The mechanisms that are involved in metal homeostasis and
