Development of a quantitative PCR assay for enumerating geosmin-producing Anabaena in Cheney Reservoir. (A) Standard curve used for the qPCR assay. (B) Relationship between geosmin concentrations measured by GC-MS and qPCR estimates of Anabaena geosmin synthase genes (geoA) for all sites in 2013 and 2014 transects. (C) Relationship between geosmin concentrations and Anabaena cell concentrations counted microscopically for the routine monitoring site in 2013 and 2014.
