Transcript analysis in Trichoderma reesei strains bearing Rut-C30-related mutations. Rut-C30 (yellow bars), QM6a-CREI96 (red bars), the Δcre1-strain (blue bars), and the Δscaff15-strain (purple bars) were pre-grown on glycerol and then transferred to medium supplemented with sophorose and incubated for 3 hours. The transcript level analysis of the cbh1 (a), cbh2 (b), and xyr1 (c) genes was performed by qPCR using sar1 and act genes for data normalization. Levels refer to the wild-type strain QM6a incubated without carbon source. The values are means from measurements and biological experiments (cultivations) performed in triplicate. Error bars indicate standard deviations.
