Figure S3. Quantitative RT-PCR analysis of gene araR, gene araD and gene ptk to assess the impact of L-arabinose on transcription of the gene cluster araR-araD-araA1-ptk. The fold difference in gene expression is calculated as the gene expression level in the cultures (grown in D-glucose-L-arabinose mixture) divided by that of the wild-type strain grown in L-arabinose.
