Electropherogram of an endophyte microsatellite fingerprint. Genomic DNA from Tf28 was amplified in the presence of fluorescent primers, and the products were separated by PAGE. GeneScan 2.1 software was used to generate the electropherogram, and the sizes of the products were determined by reference to GS-500 TAMRA internal size standards. Peaks in red, blue, green, and black correspond to the size standards: 6-FAM (B4 and B6), TET (B9 and B10), and HEX (B11)-labeled products, respectively.
