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.
