Transcriptional analysis of xlnA, xlnB, xlnC, and xlnR. Each strain was cultured under d-xylose-induced conditions (xyl) and under d-xylose plus d-glucose conditions (xyl + glc). Transcription levels of the genes before the addition of the monosaccharides are also included (0 h). The qPCR data were normalized with actA encoding γ-actin and are shown on a logarithmic scale of 2 to base (log₂ (gene/actA × 10⁴)). White bars, the reference strain; light gray bars, ΔcreA; dark gray bars, ΔpkaA; filled bars, ΔcreAΔpkaA; dashed bars, ΔganB; striped bars, ΔcreAΔganB. Error bars indicate the standard deviations of three independent experiments. Different letters indicate significant differences at P < 0.05 by one-way ANOVA with Tukey’s post hoc test
