Table 2. Long-term evolution experiment.

The table lists culture collection identities and the number of passages they were evolved (in the presence of a bacterial selection pressure). All controls were passaged for 120 times except C. glabrata, which was passaged for 130 passages). Strains that underwent large-scale genomic rearrangements were derived from species in bold.

^aNumber of passages in which yeasts were evolved in the absence of bacteria, i.e. controls

^bNumber of passages in which yeasts were evolved in the presence of bacteria. For example, C. glabrata was passaged for 120 times

^cLines which underwent rearrangements out of 3 evolution lines grown in the presence of bacteria.

^dGenomic rearrangements reported elsewhere [16].
