COPS7A and infection: As presented in Figure 5, with the exception of Aacsn6, the expression of other csn subunit genes in the ΔAacsn5 mutant was increased during infection and even more elevated during conidiation, indicating a negative feedback effect of Aacsn5 on the expression of csn1–4 and csn7, which may be involved in the conidiation process.
