Growth curves of the strains de3-01-CG and of two Ade + revertants on YEPD and SDNA+ade plates The number of cells/colony (fitness) on SDNA+ade (dotted lines) and on YEPD (continuous lines) is plotted against days in culture. We compared the strain de3-01-CG (triangles ▲) with two Ade+ revertants (strain 10, open circles ○; strain 15, closed circles ●).
