SUMMARY BAX Inhibitor‐1 (BI‐1) is a protein that controls heterologous BAX‐induced cell death, the hypersensitive reaction and abiotic stress‐induced cell death in plants. When over‐expressed in epidermal cells of barley, barley BI‐1 induces susceptibility to the biotrophic fungal pathogen Blumeria graminis . When we expressed barley BI‐1 in carrot susceptible to the necrotrophic fungus Botrytis cinerea , we obtained BI‐1‐mediated resistance to fungus‐induced leaf cell death and less fungal spreading on the leaves. Barley BI‐1 also mediated resistance to Chalara elegans in carrot roots. The results support the idea that cell death inhibition is an applicable approach to control cell‐death‐inducing pathogens in crop plants.
