In most pathosystems, virulence is dependent on hydrolases - and the wider class of cell wall degrading proteins - that degrade the cell wall. The vast majority of CWDPs are pathogen-produced and pectin-targeted (for example, pectinesterase, pectate lyase, and pectinases). For microbes the cell wall polysaccharides are themselves a food source, but mostly just a barrier to be overcome.
