Abstract
The Aspergillus nidulans xylanase genes xlnA and xlnB are subject to r egulation by ambient pH via the zinc finger transcription factor PacC. In the presence of D-xylose, xlnA is expressed under conditions of al kaline ambient pH while xlnB is expressed at acidic ambient pH. These data have been confirmed for acidity-and alkalinity-mimicking A. nidul ans mutants.
