Phytoparasitic nematodes can infect a wide range of crop plants, and cause billions of dollars of agricultural losses each year. These parasites represent the largest source of biotic stress experienced by plants. The order Tylenchida comprises the most important parasitic nematodes, particularly the root-knot and cyst nematodes. These parasitic organisms obtain nutrients to support their development through complex interactions with their hosts. Plant-parasitic nematodes secrete a mixture of

Pectate lyases are important parasitism factors in plant-parasitic nematodes. These enzymes degrade polygalacturonic acid, which is a fundamental constituent of pectin of host cell walls. Thus, pectate lyases permit the
