A ménage à trois: salicylic acid, growth inhibition, and immunity
2022年5月1日 · Is SA-triggered growth inhibition a specific, regulated reaction or is it a side-effect of the SA pathway drawing resources to implement antimicrobial responses? More importantly, can SA-dependent growth inhibition be uncoupled from immunity? To conciliate pathogen defense and good growth it is necessary to understand this aspect of plant ...
Simple Bioassay for PAMP-Triggered Immunity in Rice
2022年1月1日 · Pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) is an essential layer of plant disease resistance. Robust bioassays for PTI are pre-required to dissect its molecular mechanism. In this study, we established that lateral root growth inhibition as a simple and robust measurement of PTI in rice seedlings.
Long-Term Consequences of PTI Activation and Its Manipulation …
2024年3月29日 · Recent studies have demonstrated that root-associated commensal microbes can activate or suppress immune responses to variable extents, clearly pointing to the role of PTI in root–microbiota interactions.
Regulation of pattern-triggered immunity and growth by …
2022年8月1日 · PEP sensing by PEPR1/2 induces immune responses and inhibition of primary root growth via auxin signalling and differential modulation of PIN2/3. This is in contrast to FLS2-mediated root growth inhibition, which is independent of auxin.
The pathogen-induced peptide CEP14 is perceived by the …
2024年10月16日 · Here, we report that a group II CEP peptide, CEP14, functions as a pathogen-induced elicitor of Arabidopsis immunity. In response to infection by the bacterial pathogen Pseudomonas syringae, CEP14 expression was highly induced via the salicylic acid pathway in Arabidopsis leaves and roots.
Ligilactobacillus-Derived Extracellular Vesicles Inhibit Growth and ...
2 天之前 · Bacterial intra-kingdom communication involves the secretion of outer membrane vesicles as signaling carriers to the target cells. However, limited research exists on extracellular vesicles (EVs) from Gram-positive gut bacteria, their interactions with enteric pathogens, and potential inhibitory effects. In this study, we characterized the structure, protein content, and inhibitory effects of ...
Disease Resistance Gene-Induced Growth Inhibition Is Enhanced …
2013年1月30日 · Here, we utilize the autoimmune response mutant suppressor of npr1, constitutive1 (snc1) resulting from an activated form of the Disease Resistance (R) gene to dissect the genetic component mediating growth inhibition in Arabidopsis (Arabidopsis thaliana).
Perception of the pathogen‐induced peptide RGF7 by the …
2021年1月17日 · We report here that the Arabidopsis thaliana secreted peptide, ROOT MERISTEM GROWTH FACTOR 7 (RGF7), functions as an endogenous elicitor to trigger plant immunity. Expression of the RGF7 precursor-encoding gene (preRGF7) is highly induced in Arabidopsis leaves upon infection by the bacterial pathogen Pseudomonas syringae.
The Arabidopsis P450 protein CYP82C2 modulates jasmonate-induced …
2010年3月30日 · We demonstrate that CYP82C2 affects JA-induced accumulation of the IG biosynthetic precursor tryptophan (Trp), but not the JA-induced IAA or pathogen-induced camalexin. Together, our...
Pattern-Triggered Oxidative Burst and Seedling Growth Inhibition …
2019年5月21日 · Presented first is a method for capturing the rapidly-induced and dynamic oxidative burst, which can be monitored using a luminol-based assay. Presented second is a method describing how to measure immune-induced inhibition of seedling growth.
