Molecular Plant Pathogen Detection Lab

The Molecular Plant Pathogen Detection Lab utilizes molecular techniques to identify plant pathogens.  Pathogens will be identified by colony morphology, polymerase chain reaction (PCR), and by real-time PCR.  DNA is extracted from symptomatic tissue and prepared for PCR.  The PCR process allows us to amplify a trace amount of pathogen DNA into a larger and detectable amount of DNA.  This technique identifies pathogens much faster than traditional techniques, and identifies pathogens that are difficult to isolate and culture.  The purpose of the lab is to support South Carolina growers in the early detection of plant diseases.  The lab also identifies plant diseases of USDA-APHIS regulatory concern.
