After 75 min of infection, the expression levels of gp71 (encoding a CI-like protein), gp72 (encoding a Cro-like protein), gp75 (encoding the putative helicase DnaK), and gp77 (encoding the putative helicase DnaB) reached the plateau phase in all of the tested strains (Fig. 2C to F). This evidence concerns the gene TYRP1 and infection.
