AB  - Potato cyst nematodes (PCNs), such as Globodera pallida and Globodera 
      rostochiensis, are some of the most agriculturally and economically important 
      pests of potato. Upon nematode infection, a principal component of plant defense 
      is the generation of the reactive oxygen species (ROSs). ROSs are highly toxic 
      molecules that cause damage to pathogens and host alike. To infect the plant, 
      nematodes protect themselves from ROSs by activating their own antioxidant 
      processes and ROS scavenging enzymes. One of these enzymes is a superoxide 
      dismutase (SOD; EC 1.15.1.1), which prevents cellular damage by catalyzing 
      conversion of the superoxide radical (O(2)(-.)) to hydrogen peroxide (H(2)O(2)) 
      and molecular oxygen (O(2)). We have isolated a putatively secreted isoform of a 
      Cu-Zn SOD (SOD-3) from G. pallida and localized the expression of this gene in 
      the posterior region of the nematode. Furthermore, we studied the expression of 
      the SOD-3 gene during early parasitic stages of infection (24 to 72 h) in the 
      susceptible potato cultivar Desiree, the resistant potato cultivar Innovator, and 
      an immune host, Solanum sisymbriifolium. The SOD-3 gene was significantly 
      upregulated, regardless of the host type; however, the expression pattern 
      differed between the susceptible and the resistant or immune hosts. This finding 
      suggests that SOD-3 gene is responding to infection in plant roots differently 
      depending on whether the nematode is experiencing a compatible or an incompatible 
      interaction.
