(C) A Venn diagram showing the overlaps of the DETs of the three genotypes after WDV infection (Adopted from Sharaf et al., 2023) 3.3 Role of transcription factors in regulating resistance responses Transcription factors (TFs) are key regulators of gene expression in response to pathogen attacks. In wheat, the MYB transcription factor family has been implicated in resistance to the Wheat Dwarf Virus (WDV). Studies have shown that MYB TFs are differentially expressed in resistant and susceptible wheat genotypes, indicating their role in modulating resistance responses (Sharaf et al., 2023). Furthermore, the involvement of N6-methyladenosine (m6A) methylation in the regulation of TFs has been highlighted in the context of wheat resistance to wheat yellow mosaic virus (WYMV). This epigenetic modification affects the expression of genes involved in plant defense, underscoring the complex regulatory networks that govern disease resistance in wheat (Zhang et al., 2021).
