  • a Abbreviations: C.a.,C. albicans; S.c., S. cerevisiae; CoA, coenzyme A; ARS, autonomously replicating sequence.

  • b Responses are expressed as the fold change relative to the value for the nontreated control strain from one representative experiment. Only those genes whose expression changed 2.5-fold or more are shown. Genes induced by treatment have a positive numerical value, while those that were repressed have a negative value. The responses shown are averages for two or more datum points.
