Uptake and transfer of heavy metals by plants are often dependent on the soil pH, organic matter, CEC etc. Do you think root mycorrhiza of plants have roles to play too?
no, i think that the micorrhiza play a significant role in the heavy metal removal ,because they increase the surface area and simlutaneously increase the heavy metal uptake capacity.....
