Identification of the C2H2 Type Zinc Finger Transcription Factor Family in Aspergillus Flavus and Aspergillus Oryzae and Their Expression Profiles in Aspergillus Oryzae

C2H2 zinc protein transcription family members play an important biological role in the mitotic bacteria. The study identified 25 and 26 families of C2H2 zinc dead, respectively, in Aspergillus flavus and Aspergillus oryzae genome databases. According to phytogenetics and fantasy analysis, the families of C2H2 zinc can be divided into four subfamilies. Genes in this family are distributed across eight chromosomes. In addition, the relationship of structure and function of C2H2 zinc transfer factors was comprehensively analyzed to intuitively understand the features of protective drawings. It also analyzed the expression profiles of the transcription factors of C2H2 under salt stress treatment and different growth phase. As a result, under salt stress treatment, C2H2 zinc has a relatively low algebraic and downward regulation of transcription factors. This work has a deeper understanding of the evolution and function of C2H2 zinc transcription factors in Aspergillus flavus and Aspergillus oryzae, and helps improve gene improvement of strains to adapt to complex surroundings.
