The Saccharomyces cerevisiae BDF1 gene, which encodes a bromodomain-containing transcription factor, was previously isolated by transposon mutugenesis in a screen for salt-sensitive mutants. However, the salt stress response mechanism regulated by bromodomain transcription factor 1 protein (Bdf1p) remains poorly understood. In this report, genetic analysis indicated that the salt sensitivity of the BDF1 deletion mutant was suppressed by increased gene dosage of its homologous gene BDF2. Furthermore, comparative transcriptome analysis revealed that the differences in transcriptional response between the wild type and the bdf1Delta mutant in the presence of salt stress (0.6 mol/L NaCl, 45 min) were mainly related to cell-wall biosynthesis, the mitochondria, and several unknown genes. Our results provided further information about the regulatory mechanism involved in the salt stress response and adds new insight for understanding the biological functional of bromdomain-containing proteins in cellular processes.
