An effector protein of the wheat stripe rust fungus targets chloroplasts and suppresses chloroplast function

Abstract

Chloroplasts are important for plant immunity against microbial pathogens. Here Xu et al. identify, in the wheat stripe rust fungus, a haustorium-specific protein that is translocated into chloroplasts and affects chloroplast function by interacting with a putative component of the plant cytochrome b6-f complex.
