Some Pathogenesis-Related Proteins Are Chitosanases with Lytic Activity Against Fungal Spores

Abstract

Chitosanases represent another type of hydrolase in IF extracts of stressed plant tissue with activity toward a specific fungal cell wall polysaccharide. This is the first report of extracellular stress-related plant chitosanases distinct from chitinases that can be lytic to fungal spores of some plant pathogens
