Genome-wide identification of the GATA transcription factor family and their expression patterns under temperature and salt stress in Aspergillus oryzae

Abstract GATA transcription factors (TFs) are involved in the regulation of growth processes and various environmental stresses. Although TFs abiotic stress plants some fungi have been analyzed, information regarding Aspergillus oryzae is extremely poor. In this study, we identified functionally characterized seven proteins from A. 3.042 genome, including a novel AoSnf5 TF with 20-residue between Cys-X 2 -Cys motifs which was found for first time. Phylogenetic analysis indicated that these A . could be classified into six subgroups. Analysis conserved demonstrated similar motif compositions clustered one subgroup, suggesting they might possess genetic functions, further confirming accuracy phylogenetic relationship. Furthermore, expression patterns under temperature salt stresses were mainly responsive to high stress. The protein–protein interaction network revealed certain potentially interacting proteins. comprehensive will beneficial understanding their biological function evolutionary features provide an important starting point understand role distinct conditions
