Abstract

In culture, Rosellinia desmazieresii, the agent of a ring-dying disease in Salix repens, which can penetrate intact periderm surfaces in its host, produced a range of cell-wall-degrading enzymes. These included esterases that may be important in the depolymerization of suberin. Slow breakdown of suberin by this fungus was demonstrated.
