Similarly, in the mutant strain, bE1, bW1, Hdp1, Rbf1, and Prf1 exhibited significant upregulation after 3 days of infection; however, at the early stages (3 days) of infection, the expression levels of all genes in the UeMsb2 deletion strains were significantly lower than in the wild-type and complementation strains. Here, PRF1 is linked to infection.
