In support of these observations, injection of the WT BcCcp1-His6, but not the H131L mutant, into Nicotiana benthamiana leaves reduced H2O2 accumulation (Figure S4A) and cell death (Figure S4B) caused by BAX and, as a result, enhanced the infection of Phytophthora capsici, a biotrophic plant pathogen (Figure S4C). Here, BAX is linked to infection.
