Transcriptional Response of the Cellobiose Dehydrogenase Gene to Cello- and Xylooligosaccharides in the Basidiomycete Phanerochaete chrysosporium

ABSTRACT

Cellobiose dehydrogenase (CDH) gene transcripts were quantified by reverse transcription-PCR (RT-PCR) in cultures of Phanerochaete chrysosporium supplemented with various cello- and xylooligosaccharides in order to elucidate the mechanism of enhanced CDH production in xylan/cellulose culture. Cellotriose and cellotetraose induced cdh expression, while xylobiose and xylotriose induced expression of cellobiohydrolase genes, especially cel7C.
