The article offers information on the study conducted by the authors related to localization of DIR1 at the tissue, cellular and subcellular levels during Systemic Acquired Resistance (SAR) in arabidopsis using DIR1. It states that SAR is an induced resistance response to pathogens, characterized by the translocation of a long-distance signal from induced leaves to distant tissues to prime them for increased resistance to future infection.
