Regulatory genes in Aspergillus nidulans.


A major area for the study of gene regulation in lower eukaryotes has been the coordinated control of catabolic enzyme synthesis. Studies of catabolic gene regulation aim to define how interactions between input signals and regulatory proteins are transmitted to the transcription machinery to bring about changes in gene expression. In the past, mutants altered in the utilization of a wide variety of substrates have been characterized in Aspergillus nidulans. Recently, the development of a transformation system for A. nidulans has meant that molecular techniques can now be combined with the traditional genetic approach.
