Pathology techniques

Scientist:
Dr. Dan Opegnorth

 

Current projects

  • Diagnostic Pathology using highly sensitive bio-technology techniques such as ELISA, PCR and Real Time PCR.

Mycology


Fungal pathogens and diseases

Scientists:
Dr. Cheryl Blomquist
Dr. Suzanne Latham-Rooney

 

Current projects

  • Identification of new plant diseases caused by fungi and oomycetes in California. Identification methods include using microscopic morphological characters, genetic sequence, ELISA and pathogenicity tests.
  • Develop new and refine established methods for molecular detection of fungal plant pathogens that cause both new and existing disease problems in California.
  • Dr. Latham-Rooney:
    • Biology and etiology of fungal pathogens and diseases of grapevine.
