Systemic Acquired Resistance in Moss: Further Evidence for Conserved Defense Mechanisms in Plants

Abstract: Vascular plants possess multiple mechanisms for defending themselves against pathogens. One well-characterized defense mechanism is systemic acquired resistance (SAR). In SAR, a plant detects the presence of a pathogen and transmits a signal throughout the plant, inducing changes in the expression of various pathogenesis-related (PR) genes. Once SAR is established, the plant is capable of mounting rapid responses to subsequent pathogen attacks. SAR has been characterized in numerous angiosperm and gymnosperm s… Show more

“…Systemic acquired resistance (SAR) is an inducible defence mechanism that provides protection in distant, pathogen-free parts of plants against a broad range of pathogens. In practice, SAR has been recognised as a strategy to control plant pathogens because of its stability [ 1 ], long-lasting effectiveness [ 2 ], and transgenerational effect [ 3 ]. In the latter case, defence mechanisms are induced faster in the progeny after pathogen infection.…”

“…In bryophytes, several changes in host subcellular organization are observed during interactions with symbiotic or pathogenic microbes. In moss, filamentous necrotrophic pathogens induce cytoplasmic shrinkage as well as chloroplast repositioning and degradation, which ultimately leads to cell death ( Davey et al 2009 , Oliver et al 2009 , Ponce de Leon 2011 , Lehtonen et al 2012 , Winter et al 2014 , Yan et al 2017 ). In comparison, interactions between P. patens and the hemi-biotrophic pathogen P. capsici are associated with the accumulation of cytoplasm and the repositioning of actin filaments and nuclei towards sites of hyphal invasion ( Overdijk et al 2016 ).…”

“…The use of an inducible defense system, named acquired resistance (AR) has been well demonstrated in plants ( Heath, 2000 ; Conrath, 2006 ; Winter et al , 2014 ). AR or systemic acquired resistance (SAR) is a form of inducible resistance that is triggered systemically in plants.…”
