Comparison of different fungal expression profiles induced by polysaccharides. Expression profiles induced by polysaccharides were compared between strain Z5 and other two filamentous fungi, N. crassa and A. niger, by the method of detrended correspondence analysis. The percentages of the first two principal components explaining the expressional variations were given in axis tags. a Expression profiles of 5557 homologous genes were compared between strain Z5 and N. crassa. AF.X.16h, AF.A.16h and AF.R.16h: induction by xylan, avicel and rice straw respectively for 16 h in A. fumigatus Z5. NC.X.4h, NC.A.4h, NC.P.4h, NC.OPP.4h and NC.noC.4h: induction by xylan, avicel, pectin, orange peel power and no carbon respectively for 4 h in N. crassa. b Expression profiles of 7246 homologous genes were compared between strain Z5 and A. niger. AN.W.6h and AN.noC.6h: induction by wheat straw and no carbon respectively for 6 h in A. niger. AN.noC.24h: induction by no carbon for 24 h in A. niger. c 392 homologous CAZyme genes were compared between strain Z5 and A. niger, which were induced by polysaccharides and no carbon (shown up). d 241 homologous CAZyme genes were compared between strain Z5 and N. crassa
