Diversity of Native Arbuscular Mycorrhiza Extraradical Mycelium Influences Antioxidant Enzyme Activity in Wheat Grown Under Mn Toxicity

Sustainable agricultural practices based on the development of native arbuscular mycorrhizal fungi (AMF) can improve crop growth and stress tolerance in acidic soils with manganese toxicity. The beneficial effects are stronger when crops are colonized early in development by an intact extraradical m...

Description
Summary:Sustainable agricultural practices based on the development of native arbuscular mycorrhizal fungi (AMF) can improve crop growth and stress tolerance in acidic soils with manganese toxicity. The beneficial effects are stronger when crops are colonized early in development by an intact extraradical mycelium (ERM), but are dependent on AMF assemblage. In wheat colonized by AMF associated to Lolium rigidum L. (LOL) or Ornithopus compressus (ORN), growth and stress tolerance are differently influenced. In the present study, this functional diversity was studied by evaluating the activity of ascorbate peroxidase (APX), catalase (CAT), glutathione reductase (GR), guaiacol peroxidase (GPX), superoxide dismutase (SOD) and Mn-SOD. ORN treatment promoted higher wheat shoot and root dry weights, a higher root protein content, decreased root APX, GR and SOD activities but a higher proportion of MnSOD activity. ORN associated microbiota differently manage antioxidant enzyme activity of succeeding wheat to improve growth.
