Abstract

As sessile organisms, plants have developed well-orchestrated molecular mechanisms in response to microbial pathogens. Multiple immune signaling pathways coordinated by several subcellular compartments and interactions between organelles play an important role in the activation of a successful immune response against invading pathogens. Interestingly, pathogens target various organelles to manipulate plant immune system directly or indirectly. Chloroplasts are a primary production site of pro-defense molecules. In addition, it is a favorite target of effector proteins, which are delivered from pathogens to inhibit plant immune responses. Recently stromules, dynamic tubular extensions from chloroplasts, have been proposed to transport pro-defense signals generated from chloroplasts into the nucleus during immunity. Interestingly, microtubules regulate stromule extension and retraction while actin filaments anchor stromule surrounding nuclei, facilitating the clustering of chloroplasts to nuclei during plant immune responses. In addition, induction of stromule is correlated to the hypersensitive responsive programmed cell death (HR-PCD) triggered by the recognition of effector proteins secreted from pathogens into plant cells.
