Identification of Heterodera cysts
A biochemical method for the identification of Hederodera species using cysts has been studied. By examining the isoforms of an enzyme (superoxide dismutase) in polyacrylamide gel electrophoresis, different profiles could be obtained for six species H. avenae, H. cruciferae, H. glycines (EPPO A1 quarantine pest), H. goettingiana, H. schachtii, and H. trifolii. Authors felt that studies should be extended to other Heterodera species and to intraspecific variation. As this method is rapid, it may have the potential for routine testing in diagnostic laboratories.
