Fig. 1From: Improvement of yeast tolerance to acetic acid through Haa1 transcription factor engineering: towards the underlying mechanismsHaa1-induced activation of the four selected target genes within the Haa1-regulon that are relevant in the current study and involved in the adaptation to acetic acid stress. Upon exposure of cells to acetic acid, Haa1 binds to the promoter region of its target genes and thereby regulates their expression. We refer to the background section for more detailed information regarding the function of the depicted target genesBack to article page
