Zn(Ⅱ)2Cys6-type transcription factors play pivotal regulatory roles in various biological processes in fungi, including primary and secondary metabolism, stress responses, and cell division. In this study, a hidden Markov model (HMM) was employed to screen the whole genome of Pleurotus giganteus, and 67 genes belonging to the Zn(Ⅱ)2Cys6-type transcription factor family were identified. Motif analysis revealed distinct sequence features among the family members. Phylogenetic analysis further classified these 67 genes into four major clades. Based on transcriptomic data, 53 family genes with differential expression were identified under 10 μmol/L Cd2+ stress for 3 h, 6 h, and 12 h, as well as under 100 μmol/L Cd2+stress for 3 h, 6 h, 12 h, and 24 h. By using weighted gene co-expression network analysis (WGCNA), gene co-expression network topological analysis, and GO/KEGG enrichment analysis of co-expressed genes, the regulatory functions of some differentially expressed family genes were predicted. This study provides a scientific basis for further understanding of the role of Zn(Ⅱ)2Cys6-type transcription factor family in the response mechanisms of P. giganteus to cadmium stress.
