Two modes of plant immunity against biotrophic pathogens, Effector Triggered Immunity (ETI) and Pattern-Triggered (PTI), are triggered by recognition pathogen effectors Microbe-Associated Molecular Patterns (MAMPs), respectively. Although the jasmonic acid (JA)/ethylene (ET) salicylic (SA) signaling sectors generally antagonistic important for necrotrophic respectively, their precise roles interactions in ETI PTI have not been clear. We constructed an Arabidopsis...
Recognition of microbial patterns by host pattern recognition receptors is a key step in immune activation multicellular eukaryotes. Peptidoglycans (PGNs) are major components bacterial cell walls that possess immunity-stimulating activities metazoans and plants. Here we show PGN sensing immunity to infection Arabidopsis thaliana requires three lysin-motif (LysM) domain proteins. LYM1 LYM3 plasma membrane proteins physically interact with PGNs mediate sensitivity structurally different from...
Summary Plants respond to pathogen infection using an innate immune system with at least two distinct recognition mechanisms. One mechanism recognizes microbe‐associated molecular patterns (MAMPs). The other is based on resistance (R) genes and specifically certain virulence factors, including those delivered through the type III secretion (TTSS) of bacteria. Salicylic acid (SA)‐mediated responses are important part R gene‐mediated defense. Substantial overlaps between MAMP‐triggered...
Salicylic acid (SA)-induced defense responses are important factors during effector triggered immunity and microbe-associated molecular pattern (MAMP)-induced in plants. This article presents evidence that a member of the Arabidopsis CBP60 gene family, CBP60g, contributes to MAMP-triggered SA accumulation. CBP60g is inducible by both pathogen MAMP treatments. Pseudomonas syringae growth enhanced cbp60g mutants. Expression profiles mutant after treatment similar those sid2 pad4, suggesting...
Arabidopsis thaliana calmodulin binding protein 60g (CBP60g) contributes to production of salicylic acid (SA) in response recognition microbe-associated molecular patterns (MAMPs) such as flg22, a fragment bacterial flagellin. Calmodulin is required for the function CBP60g limiting growth pathogen Pseudomonas syringae pv. maculicola (Pma) ES4326 and activation SA synthesis. Here, we describe closely related protein, SARD1. Unlike CBP60g, SARD1 does not bind calmodulin. Growth Pma enhanced...
In nature, plants must respond to multiple stresses simultaneously, which likely demands cross-talk between stress-response pathways minimize fitness costs. Here we provide genetic evidence that biotic and abiotic stress responses are differentially prioritized in Arabidopsis thaliana leaves of different ages maintain growth reproduction under combined stresses. Abiotic stresses, such as high salinity drought, blunted immune older rosette through the phytohormone abscisic acid signaling,...
The phytohormone salicylic acid (SA) is a small phenolic compound that regulates diverse physiological processes, in particular plant resistance against pathogens. Understanding SA-mediated signaling has been major focus of research. Pathogen-induced SA mainly synthesized via the isochorismate pathway chloroplasts, with ICS1 (ISOCHORISMATE SYNTHASE 1) being critical enzyme. Calcium activities subset transcription factors thereby activating nuclear expression. produced triggers extensive...
Network robustness is a crucial property of the plant immune signaling network because pathogens are under strong selection pressure to perturb components dampen responses. Nevertheless, modulation an area biology that has rarely been explored. While two modes immunity, Effector-Triggered Immunity (ETI) and Pattern-Triggered (PTI), extensively share machinery, output much more robust against perturbations during ETI than PTI, suggesting robustness. Here, we report molecular mechanism...
Perception of microbe-associated molecular patterns by host cell surface pattern recognition receptors (PRRs) triggers the intracellular activation mitogen-activated protein kinase (MAPK) cascades. However, it is not known how PRRs transmit immune signals to MAPK cascades in plants. Here, we identify a complete phospho-signaling transduction pathway from PRR-mediated pathogen We found that receptor-like cytoplasmic PBL27 connects chitin receptor complex CERK1-LYK5 and cascade. interacts with...
Abstract Environmental conditions profoundly affect plant disease development; however, the underlying molecular bases are not well understood. Here we show that elevated temperature significantly increases susceptibility of Arabidopsis to Pseudomonas syringae pv. tomato ( Pst ) DC3000 independently phyB/PIF thermosensing pathway. Instead, promotes translocation bacterial effector proteins into cells and causes a loss ICS1-mediated salicylic acid (SA) biosynthesis. Global transcriptome...
Plant pathogens can cause serious diseases that impact global agriculture. The plant innate immunity, when fully activated, halt pathogen growth in plants. Despite extensive studies into the molecular and genetic bases of immunity against pathogens, influence metabolism to restrict is poorly understood. Here, we developed RNA sequencing pipelines for analyzing bacterial transcriptomes planta determined high-resolution transcriptome patterns foliar Pseudomonas syringae Arabidopsis thaliana...
The phytohormone network consisting of jasmonate, ethylene, PHYTOALEXIN-DEFICIENT4, and salicylic acid signaling is required for the two modes plant immunity, pattern-triggered immunity (PTI), effector-triggered (ETI). A previous study showed that during PTI, transcriptional responses over 5000 genes qualitatively depend on complex interactions between components. However, role in reprogramming ETI whether it differs PTI remain elusive. Here, we generated time-series RNA-sequencing data...
Pattern-triggered immunity (PTI) and effector-triggered (ETI) are required for host defense against pathogens. Although PTI ETI intimately connected, the underlying molecular mechanisms remain elusive. In this study, we demonstrate that flg22 priming attenuates Pseudomonas syringae pv. tomato DC3000 (Pst) AvrRpt2-induced hypersensitive cell death, resistance, biomass reduction in Arabidopsis. Mitogen-activated protein kinases (MAPKs) key signaling regulators of ETI. The absence MPK3 MPK6...
Despite the plant health-promoting effects of microbiota, these assemblages also comprise potentially detrimental microbes. How immunity controls its microbiota to promote health under conditions remains largely unknown. We find that commensal bacteria isolated from healthy Arabidopsis plants trigger diverse patterns reactive oxygen species (ROS) production dependent on immune receptors and completely NADPH oxidase RBOHD selectively inhibited specific commensals, notably Xanthomonas L148....
Recognition of molecular patterns characteristic microbes or altered-self leads to immune activation in multicellular eukaryotes. In Arabidopsis thaliana , the leucine-rich-repeat receptor kinases FLAGELLIN-SENSING2 ( FLS2 ) and EF-TU RECEPTOR EFR recognize bacterial flagellin elongation factor EF-Tu (and their elicitor-active epitopes flg22 elf18), respectively. Likewise, PEP1 RECEPTOR1 PEPR1 PEPR2 Pep conserved ELICITOR PEPTIDE PRECURSOR s PROPEP s). Here we reveal that loss...
The initiation of flowering is an important developmental transition as it marks the beginning reproductive phase in plants. MADS-box transcription factors (TFs) FLOWERING LOCUS C (FLC) and SHORT VEGETATIVE PHASE (SVP) form a complex to repress expression genes that initiate Arabidopsis. Both TFs play central role regulatory network by conferring seasonal patterns flowering. However, their interdependence biological relevance when acting have not been extensively studied.We characterized...
Pattern-triggered immunity (PTI) is triggered by recognition of elicitors called microbe-associated molecular patterns (MAMPs). Although immune responses may provide good protection plants from pathogen attack, excessive have negative impacts on plant growth and development. Thus, a balance between positive effects the signaling network important for fitness. However, little information known about mechanisms that are involved in attenuation PTI. Here, we describe growth-promoting peptide...
