Chloroplasts are important for photosynthesis and for plant immunity against microbial pathogens. Here we identify a haustorium-specific protein (Pst_12806) from the wheat stripe rust fungus,Puccinia striiformisf. sp.tritici(Pst), that is translocated into chloroplasts and affects chloroplast function. Transient expression ofPst_12806inhibits BAX-induced cell death in tobacco plants and reducesPseudomonas-induced hypersensitive response in wheat. It suppresses plant basal immunity by reducing callose deposition and the expression of defense-related genes.Pst_12806is upregulated during infection, and its knockdown (by host-induced gene silencing) reducesPstgrowth and development, likely due to increased ROS accumulation. Pst_12806 interacts with the C-terminal Rieske domain of the wheat TaISP protein (a putative component of the cytochrome b6-f complex). Expression ofPst_12806in plants reduces electron transport rate, photosynthesis, and production of chloroplast-derived ROS. SilencingTaISPby virus-induced gene silencing in a susceptible wheat cultivar reduces fungal growth and uredinium development, suggesting an increase in resistance againstPstinfection.
