Chemical Composition fo the Glue From Appressoria of Magnaporthe grisea

Abstract

  The chemical composition of the glue substance that attaches the appressoria of Magnaporthe grisea bar artificial leaf wax was investigated. As a percentage of fresh weights, the glue was crude lipids 29.0%, proteins 12.2%, sugars 7.6%, water 26.5% and other substances 24.7%. The major fatty acid components of the crude lipids were hexadecanoic and octadecanoic acids. Unsaturated fatty acids and branched fatty acids were also detected as minor components. The protein was abundant in glycine, glutamic acid, and serine. Glucose, xylose, and mannose were the major monosaccharides.
