The expression of nucleus-targeted GFP under the control of the agsA promoter in A. niger in response to cell wall interfering substances. Differential interfering contrast images and corresponding fluorescence images of A. niger RD6.47 indicate the expression of a nucleus-targeted GFP under the control of the A. niger agsA promoter. Five h old germlings were (A) left untreated (negative control), (B) treated with 50 μg/ml AFPNN5353 and (C) with 10 μg/ml caspofungin (positive control) as described in Materials and Methods. Scale bar, 20 μm.
