Comparison of protein profiles and enzymes in non-mycorrhizal and mycorrhizal roots of <i>Pennisetum pedicellatum</i>

Abstract

<i>Pennisetum pedicellatum</i> plants were inoculated with <i>Glomus mosseae</i>,<i> G</i>. <i>aggregatum </i>and <i>Gigaspora margarita. </i>There were both quantitative and qualitative changes in the protein pattern of inoculated plants. <i>Gi</i>. <i>margarita </i>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. <i>Gi</i>. <i>margarita </i>was an efficient fungus in enhancing enzyme activity and proteins in roots compared with <i>G.mosseae </i>and <i>G.aggregatum. </i>Protein profile revealed the presence of 12 peaks in mycorrhizal plants compared with 8 in nonmycorrhizal plants.
