Resolution of Endopolygalacturonase and a Macerating Factor in a Fungal Culture Filtrate
Abstract
THE brown rot fungi, Sclerotinia fructigena Aderh. and Ruhl., and S. laxa Aderh. and Ruhl., are known to penetrate infected fruits by dissolution of the middle lamella1, and the macerating effect of culture filtrates of these fungi on disks of plant tissue has been ascribed to pectolytic enzymes2. The separate identity of `protopectinases' (using the nomenclature of Demain and Phaff3) has been questioned in recent reviews3,4; but the presence of distinct fungal macerating enzymes, without characterized substrates, has been reported in a commercial poetic enzyme5 and in culture filtrates of two plant-pathogenic fungi5,6.
