abstract：:The stress-responsive DDR2 gene (previously called DDRA2) of Saccharomyces cerevisiae is transcribed at elevated levels following stress caused by heat shock or DNA damage. Previously, we identified a 51-bp promoter fragment, oligo31/32, which conferred heat shock inducibility on the heterologous CYC1-lacZ reporter ge...
