Pb Transfer Preference of Arbuscular Mycorrhizal Fungus Rhizophagus irregularis in Morus alba under Different Light Intensities.

ABSTRACT: Arbuscular mycorrhizal (AM) fungi can improve the lead (Pb) tolerance of host plants and accumulate intensive Pb in mycorrhizal roots. However, the detailed contribution of AM fungal extraradical hyphae to the plants' Pb uptake remains unknown. In this study, mulberry (Morus alba) colonized by the AM fungus (Rhizophagus irregularis) with light treatments were linked by fungal extraradical hyphae using a three-compartment system (pot test), and their differences in responding to Pb application were compared. Shading inhibited mulberry photosynthesis and the growth of mulberry. In this study, Pb application did not affect the colonization of R. irregularis when symbiosis had already formed as the root was not exposed to Pb during the colonization and formation of the AM
