Fig. 7

Illustration of physiological stages of the A. niger response to (pretreated) substrates including both conserved and substrate-specific responses. After transfer to lignocellulose, A. niger reacted with a general carbon starvation response, followed by pretreatment and feedstock specific elements such as mannan degradation on straw but not Miscanthus, followed by a general carbon-limitation induced response with sporulation and induction of secondary metabolite clusters. Stand-out features of the response are indicated for each condition. Green and red arrows represent processes that were increased or decreased, respectively. CAZy transcript levels and pentose concentration are represented as average (for all or stated conditions) percentage of the maximum with identical y-axes in all instances. The width of blue and grey panels represent the covered time-period, marked on the time-scale as h after transfer to lignocellulose
