In the original article, there was an error. A reference paper evidencing the effect of autoregulation of transcription factor AlcR in Aspergillus nidulans (Lockington et al., 1987) was missed during data collection. Thus, the description that “the consequent regulatory effects have not been clarified through low-throughput experiments” is incorrect for AlcR. The citation has been added and a correction has made to Results and Discussion, Structural Features of Transcriptional Regulatory Networks, Autoregulation:
Twelve and eight TFs were identified as autoregulating TFs in A. nidulans and N. crassa, respectively (Table S2). Specifically, in A. nidulans, AlcR (Lockington et al., 1987), AbaA, BrlA, QutA, PacC, StuA, and AreA activate, while QutR, CreA, and HapB repress, their own expression. Also, WC-1, CPC-1, ACR-2, QA-1F, and FL activate their own expression in N. crassa. These autoregulations might enhance or attenuate the regulatory outputs of TFs in response to environmental changes. In addition, VosA and CpcA in A. nidulans and PACC, CYS-3, SRE in N. crassa can bind to their own promoters, while the consequent regulatory effects have not been clarified through low-throughput experiments to our knowledge.
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
