FIG. 5.
PCR-SSCP electropherograms from independent soil samples (A through O) collected at different locations within an agricultural field at the Hancock Agricultural Research Station. The y axis was adjusted for each electropherogram and represents relative fluorescence intensity, and the x axis represents relative migration distance. Soil samples A to I, J to L, and M to O were collected in replicated plots 12-4, 12-3, and 12-2, respectively. Profiles sharing marker 1 are along a 0.3-m transect. Profiles sharing marker 2 or 3 are within 30 or 350 m2 of each other, respectively.
