This is consistent with previous findings in strawberry in which, after infection with C. gloeosporioides, the expression of heat‐shock protein (HSP17.4) activated the up‐regulation of response genes NPR1, TGA, and PR‐1 of the SA signalling pathway and synergistically suppressed downstream signals of JA, contributing to resistance of the plants to infection (Fang et al., 2021). Here, NPR1 is linked to infection.
