The Arabidopsis NPR1 Gene That Controls Systemic Acquired Resistance Encodes a Novel Protein Containing Ankyrin Repeats
The Arabidopsis NPR1 gene controls the onset of systemic acquired resistance (SAR), a plant immunity, to a broad spectrum of pathogens that is normally established after a primary exposure to avirulent pathogens. Mutants with defects in NPR1 fail to respond to various SAR-inducing treatments, displaying little expression of pathogenesis-related (PR) genes and exhibiting increased susceptibility...
متن کاملSystemic Acquired Resistance.
One reaction of plants to pathogen infection is the induction of a long-lasting, broad-spectrum, systemic resistance to subsequent infections. This induced disease-resistance response has been known for many years under different names such as physiological acquired immunity or induced resistance; for the purpose of this update we will refer to it as SAR. Our perspective is that SAR is one comp...
متن کاملUltrastructures of Colletotrichum orbiculare in Cucumber Leaves Expressing Systemic Acquired Resistance Mediated by Chlorella fusca
Chlorella, one single-cell green algae organism that lives autotrophically by photosynthesis, can directly suppress some plant diseases. The objective of this study was to determine whether pre-spraying with Chlorella fusca suspension could induce systemic acquired resistance (SAR) in cucumber plants against anthracnose caused by Colletotrichum orbiculare. In order to illustrate SAR induced by ...
متن کاملBenzothiadiazole, a novel class of inducers of systemic acquired resistance, activates gene expression and disease resistance in wheat.
Systemic acquired resistance is an important component of the disease resistance repertoire of plants. In this study, a novel synthetic chemical, benzo(1,2,3)thiadiazole-7-carbothioic acid S-methyl ester (BTH), was shown to induce acquired resistance in wheat. BTH protected wheat systemically against powdery mildew infection by affecting multiple steps in the life cycle of the pathogen. The ons...
متن کاملSystemic Acquired Resistance in Potato
Systemic acquired resistance (SAR) is a defense mechanism that is increasingly being exploited for crop protection. However, successful utilization of SAR will likely require optimization of defense induction for each crop followed by a determination of the pathogens against which SAR is effective. We are examining the capacity of different potato tissues to mount an SAR response. Both free and...
