Polygalacturonase and xylanase forms produced by Fusarium avenaceum in infected lupin roots and their sensitivity to a cell wall glycoprotein

Abstract

Using CM-Sepharose column chromatography it was shown that Fusarium avenaceum produced two forms of endo-polygalacturonase, one exo-polygalacturonase and two forms of endo-xylanase in infected Iupin roots. A glycoprotein obtained from lupin seedlings inhibited endo-polygalacturonases, exo-polygalacturonases and xylanases but more the first ones. Two forms of endo-polygalacturonase did not differ in their sensitivity to the glycoprotein.
