Comparison of protein profiles and enzymes in non-mycorrhizal and mycorrhizal roots of Pennisetum pedicellatum.

ABSTRACT

Pennisetum pedicellatum plants were inoculated with Glomus mosseae, G. aggregatum and Gigaspora margarita. There were both quantitative and qualitative changes in the protein pattern of inoculated plants. Gi. margarita induced increase in protein in the plants. Acid phosphatase, alkaline phosphatase, superoxide dismutase and chitinase activities were high at the beginning of infection, but declined as the infection advanced. Gi. margarita was an efficient fungus in enhancing enzyme activity and proteins in roots compared with G. mosseae and G. aggregatum. Protein profile revealed the presence of 12 peaks in mycorrhizal plants compared with 8 in nonmycorrhizal plants.
