Dal81 regulates expression of arginine biosynthesis genes in Candida parapsilosis

Transcriptional profiling of Candida parapsilosis in media with a preferred nitrogen source (ammonium sulfate) and a non-preferred source (isoleucine) to identify genes that are subject to Nitrogen Catabolite Expression. Gene expression of wild type and dal81 deletion strains were compared during growth in complex nitrogen sources (YPD), in minimal media with a preferred nitrogen source (YNB+ammonium sulfate) and minimal medium with a non-preferred source (GABA). 8 independent samples with three replicates of each, generating 24 samples.
