  • Nine populations of Globodera rostochiensis were collected from Trujillo, Merida and Lara States in Venezuela. About one hundred cysts of each population were used to extract proteins. Proteins were separated according to their charge by isoelectrofocusing (IEF) on mini-gels inserted into the automated Phast-System® equipment. Gels were stained for superoxide dismutase (SOD) activity. SOD IEF patterns of Venezuelan populations were compared with 3 G. rostochiensis populations from Italy and 3 G. pallida populations, 2 from Italy and 1 from Chile. A high SOD polymorphism was found among the populations tested with the presence of up to 17 enzyme activity bands at different isoelectric point (pI range 8.7-4.1). Therefore, a cluster analysis was carried out and the 2 different Globodera spp. were clearly separated except for 2 populations from Venezuela which were clustered together with the G. pallida population from Chile. In the large G. rostochiensis group, populations from Venezuela clustered separated by the Italian populations. (literal)
