Comparison of protein patterns in non‐mycorrhizal and vesicular–arbuscular mycorrhizal roots of red clover

Abstract

A comparison of the protein content and patterns in root extracts from non‐mycorrhizal and vesicular‐arbuscular mycorrhizal [Glomus mosseae (Nicol. et Gerd.) Gerd. et Trappe] red clover (Trifolium pratense L.) has been made. Soluble protein content was higher in mycorrhizal than in non‐mycorrhizal roots. After separation by DEAE‐cellulose chromatography and electrophoretic analysis, several additional polypeptides appeared in mycorrhizal extracts. In addition, it seems that one of the additional proteins was a plant‐induced superoxide dismutase isozyme. Copyright © 1993, Wiley Blackwell. All rights reserved
