Fig. 4From: Identification and characterization of putative xylose and cellobiose transporters in Aspergillus nidulans The expression of the A. nidulans hexose transporter-encoding genes hxtB-E is upregulated in the presence of low concentrations of xylose. Transcript levels of hxtB-E (a–d) were determined by RT-qPCR in the wild-type strain when grown for 0, 6, 12, 18, and 24 h in the presence of 0.2 and 2 % xylose. Error bars indicate the standard deviation for three replicatesBack to article page
