Fitness costs of mutations affecting the systemic acquired resistance pathway in Arabidopsis thaliana.
This study investigated the fitness effects of four mutations (npr1, cpr1, cpr5, and cpr6) and two transgenic genotypes (NPR1-L and NPR1-H) affecting different points of the systemic acquired resistance (SAR) signaling pathway associated with pathogen defense in Arabidopsis thaliana. The npr1 mutation, which resulted in a failure to express SAR, had no effect on fitness under growth chamber con...
متن کاملFitness benefits of systemic acquired resistance during Hyaloperonospora parasitica infection in Arabidopsis thaliana.
We investigated the fitness benefits of systemic acquired resistance (SAR) in Arabidopsis thaliana using a mutational and transformational genetic approach. Genetic lines were designed to differ in the genes determining resistance signaling in a common genetic background. Two mutant lines (cpr1 and cpr5) constitutively activate SAR at different points in SAR signaling, and one mutant line (npr1...
متن کاملCaterpillar saliva interferes with induced Arabidopsis thaliana defence responses via the systemic acquired resistance pathway
Arabidopsis thaliana (L.) Heynh. genotypes limited in their ability to mount either octadecanoid-dependent induced resistance (IR(-)) or systemic acquired resistance (SAR(-)) were used to characterize the roles of these pathways in plant-herbivore interactions. Molecular and biochemical markers of IR were analysed in plants subject to herbivory by caterpillars of the beet armyworm, Spodoptera e...
متن کاملThe fitness costs of antibiotic resistance mutations
Antibiotic resistance is increasing in pathogenic microbial populations and is thus a major threat to public health. The fate of a resistance mutation in pathogen populations is determined in part by its fitness. Mutations that suffer little or no fitness cost are more likely to persist in the absence of antibiotic treatment. In this review, we performed a meta-analysis to investigate the fitne...
متن کاملDiscovery of Functional Genes for Systemic Acquired Resistance in arabidopsis Thaliana through Integrated Data Mining
Various data mining techniques combined with sequence motif information in the promoter region of genes were applied to discover functional genes that are involved in the defense mechanism of systemic acquired resistance (SAR) in Arabidopsis thaliana. A series of K-Means clustering with difference-in-shape as distance measure was initially applied. A stability measure was used to validate this ...
