FIG. 1.

Expression of faeA in the presence of aromatic compounds. A. niger N402 mycelium was incubated for 4 h in complete medium (blank), in complete medium containing 0.03% (mass/vol) fructose, and in complete medium containing different aromatic compounds at a concentration of 0.03% (mass/vol). The blots are Northern blots prepared as described in the text. 18S rRNA was used as an RNA loading control. Abbreviations: hydr., hydroxy; meth., methoxy; dimeth., dimethoxy; ppa, phenylpropionic acid.
