• populations
  • The aim of this research was to determine if the observed differences in the levels of infection in C. arvense populations within New Zealand was due to genetic differences between P. punctiformis isolates. (lincoln.ac.nz)
  • We examined genetic diversity among more than 2000 individuals representing nearly 100 North American populations of C. arvense using 7 different microsatellite markers. (usda.gov)
  • genetic
  • The study has indicated there is genetic diversity in P. punctiformis in New Zealand which could explain the observed differences in infection of C. arvense in the field. (lincoln.ac.nz)
  • Biological
  • P. punctiformis has the potential to be a successful biological control agent as it is already present in New Zealand and can systemically and locally infect C. arvense. (lincoln.ac.nz)
